Dinosaur Footprints

Monday, January 31, 2011


Dinosaur Valley State Park in the small town of Glen Rose. Sited about a 100 miles from Dallas this is a really small town, with even smaller population (2,400). But this small population doesn’t have anything to complain, there are fancy shopping centers, fuel stations, super markets, a police station and even a court house. I don’t know whether to call it well administered or whether there are too many crimes and litigations. Anyway that is not the reason why I liked Glen Rose.



I liked it because of its proximity to the lush green and calm Dinosaur Valley State Park, through which the river Paluxy flows. Unlike most of Texas this place is hilly and has lot of small and large wooded and rocky cliffs and vast acres of forests. Wading across the river which has fossilized footprints of Dinosaurs is a great experience. One has to be careful though, the moss and algae on river beds could be quite slippery. Now I am going to stop talking and let the pictures tell you the story of Glen Rose.

Archaeopteryx

]
Archaeopteryx is considered to be one of the most important fossils ever discovered in the world of paleontology. The skeleton is essentially that of a theropod dinosaur, and possesses teeth, a long bony tail, abdominal ribs and three digits on each hand - characters absent in birds.



However, the specimens also show certain bird characteristics such as a furcula (wishbone) and a retroverted pubis (characteristics also shared with some dinosaurs) and an opposable hallux (big toe) for perching. The most spectacular feature is the distinct impression of feathers around the forelimbs and tail. These feathers are almost exactly like those of modern birds.

New Early Dinosaur Fossils Shift Family Tree

Sunday, January 30, 2011


Scientists have discovered a four-foot-long, meat-eating dinosaur, with serrated teeth and long finger bones, that roamed the earth some 230 million years ago. The fossils are among the earliest dinosaur bones ever found, and the finding, which was published Thursday in the journal Science, has shaken up the creature's family tree.

The bones of the tiny dinosaur, which scientists have named Dawn Runner, or Eodromaeus murphi , were found encased in rock chunks in an arid Argentinian valley, known as "Valley of the Moon."

"It's significant for dinosaur origins because it's a relatively complete skeleton, and there's more than one of them," said Sterling Nesbitt, a paleontologist from the University of Washington, who specializes in early dinosaurs. "There are many questions, and the only way they can be answered is through new material."

Dawn Runner roamed the earth during the late Triassic era, before dinosaurs rose to dominance, when continents with vast desert belts were shoved together and primitive mammals and early crocodiles were abundant. It had grasping hands, walked on two feet and had air sacks in its neck vertebrae like a bird. It was svelte and scrappy, "not a big chunky bruiser animal by any means," said Mark Norell, chairman of paleontology at the American Museum of Natural History in New York City. "It was sort of the Kate Moss of the dinosaur world."

Paul Sereno from the University of Chicago was one of the two lead authors, along with Ricardo Martinez of the National University of San Juan in Argentina.

"It was a scrappy meat-eater that would come at you, and you'd be twisted around before you knew which way it went," Sereno said. "A 10 to 15-pound ball of energy. And it's got canines that are definitely for slicing and dicing meat."

Using bones from different dinosaurs, the paleontologists were able to piece together almost an entire skeleton and with it, more evidence of the beginnings of the dinosaur lineage. Scientists have identified the animal as a theropod, which means it may be a distant ancestor to both Tyrannosaurus Rex and modern birds.

The discovery has also led to the reclassification of the dinosaur, Eoraptor, which was discovered in the early 1990s by the same team. Eoraptor was originally thought to be a theropod, but this study redefines it as sauropod, an herbivore.

The finding may be controversial, Nesbitt, says, "because everyone has previously found Eoraptor to be a carnivorous dinosaur. It solves a couple questions, but creates a lot more to be answered." But, he adds, the paper puts forward convincing evidence.

"For me, the take home message is to realize that this is a good approximation of a primitive dinosaur," Sereno says. "Great things come from small beginnings like this. And...if you went back 230 million years ago, you'd likely be eaten by a crocodile. Dinosaurs would come and pick your bones."

Single-fingered dinosaur surprises scientists



Would your parents ever let you keep a dinosaur as a pet, especially one related to the fierce Tyrannosaurus rex?

What if you told your folks that it could keep pests such as ants and termites out of the house?

Scientists in China have discovered the bones of a dinosaur that kids who promised to clean their room and make honor roll might have been able to bring home. The species was as small as eight inches tall and weighed less than a pound.

The most fascinating discovery concerning Linhenykus monodactylus is that unlike the T. rex, it had one finger instead of three.

Scientists expected that as dinosaurs used their middle finger for digging, it would have gotten bigger, leading to the eventual disappearance of the two side digits. However, this dinosaur's single finger was smaller than the middle digit of three-fingered species. "We don't see this very often in dinosaur evolution," said researcher Xu Xing.

The big problem with the dinosaur-as-a-pet notion? Linhenykus monodactylus died out about 80 million years ago.

'Tiny T-rex' fossil unearthed in China

Wednesday, January 26, 2011


Fossil hunters have unearthed the remains of a man-sized forerunner to the colossal Tyrannosaurus rex from an ancient lake bed in northeastern China.

The remarkable discovery has allowed dinosaur experts to piece together a picture of a diminutive but formidable predator that was so finely tuned to killing they describe it as "Jaws on legs".

The beast, named Raptorex kriegsteini, roamed the Earth 130m years ago, tens of millions of years before the giant T-rex became the most fearsome predator in history.

The finding has stunned palaeontologists because the skeleton resembles the larger tyrannosaurs in every respect except its size. Measurements of bones recovered from the site reveal that the new species was one hundredth the size of T-rex.

Analyses of the remains by researchers at the University of Chicago and the American Museum of Natural History in New York revealed the dinosaur to be a juvenile of five or six years old, measuring nearly 3m from nose to tail and weighing only 60kg (nine stone). A similar aged T-rex could weigh several tonnes.

Though smaller than its more celebrated descendant, Raptorex was the largest meat-eater of its time. It would have enjoyed a varied diet of parrot-beaked psittacosaurs, turtles, primitive birds and a host of small, scampering dinosaurs that would have watered at the ancient lakes it lived near.

The exquisite and almost complete remains only came to light when an American eye surgeon, Henry Kriegstein, telephoned the researchers to say he had bought the fossil from a trader. Paul Sereno at the University of Chicago agreed to document the fossil – and name it after the surgeon's father – on condition that the remains were returned to China afterwards.

The Chicago team has spent the past three years preparing and studying the fossil, which was lodged in a block of sediment removed from the Lujiatun lake beds in northeast China.

Writing in the US journal Science, the researchers describe the delicate operation to clean and prepare the skeleton. The skull was sent through an X-ray scanner at a Chicago hospital before moulds and casts of the bones were made. The X-rays revealed enlarged brain regions that suggest the creature had a highly evolved sense of smell.

The discovery overturns scientists' thinking about how Tyrannosaurus rex evolved. Many of the most striking features of the beast, such as its puny forearms, were thought to be a trade-off during the evolution of its enormous size, but Raptorex shows these features had already evolved more than 60m years earlier.

"So much of what we thought we knew about Tyrannosaur evolution turns out to be simplistic or out-and-out wrong," said Stephen Brusatte, a member of the team.

"The thinking has been that as tyrannosaurs developed to a truly giant size, they needed to modify their entire skeleton so they could function as predators.

"Raptorex, the new species, really throws a wrench into this observed pattern. Here we have an animal that's one 90th or one 100th the size of T. Rex, but with all the signature features, the big head, the strong muscles and the tiny little arms.

"We can now say these features didn't evolve as a consequence of body size, but rather they just evolved as a set of efficient predatory weapons," Brusatte added.

Raptorex had powerful legs to run down its prey and a huge muscular jaw with which to dispatch them. "This is a blueprint for a predator: Jaws on legs," Sereno said.

Researchers now believe that tyrannosaurs spent almost all of their time on Earth as small, flighty predators like Raptorex. As other large dinosaurs became extinct, this left the path clear for Raptorex to expand in body size and ultimately become the giant Tyrannosaurus rex. "When it did, there was no turning back until the asteroid hit," said Brusatte.

Sereno said Kriegstein agreed to donate the fossil remains to science if the species was named in honour of his father, Roman.

"The specimen was found perhaps in the dark of night and spirited out of China and ultimately sold. [Mr Kriegman] contacted me and wondered if I would describe it. I said I would if it could be returned 100%, lock, stock and barrel to science and ultimately back to China.

Snake Caught Attacking Dinosaur—First Fossil Proof





First Fossil Evidence of Snakes Eating Dinosaurs

The snake's interrupted meal offers a rare glimpse into the feeding behavior of ancient snakes and the dangers that newborn dinosaurs faced, said study team member Jeffrey Wilson, a University of Michigan paleontologist.

"It's actually one of the very few examples that we have of anything other than a dinosaur eating a dinosaur," said Wilson, whose work was funded in part by a grant from the National Geographic Society's Committee for Research and Exploration. (The National Geographic Society owns National Geographic News.)

Scientists have long known that some dinosaurs were egg snatchers, and recent fossil evidence suggests mammals also dined on young dinosaurs. (See "Five 'Oddball' Crocs Discovered, Including Dinosaur-Eater.")

It's been suspected that snakes too ate dinosaurs, but until now there had been no proof.

"It's a rough life if you're a juicy little dinosaur," Wilson said.

Dinosaur Devourer Was Lizard-like Snake

Modern large-mouthed snakes, such as boas and anacondas, can eat large prey because their jaw joints are positioned well behind their skulls, allowing the snakes to open their mouths very wide.

But the new species of prehistoric snake has a smaller mouth opening, like a lizard's. The snake's jaw joints were no farther aft than the back of the skull itself—earning it the name Sanejeh indicus, or "ancient-gaped one from India."

Even without giant jaws, though, Sanejeh "could swallow big things"—such as baby dinosaurs— simply because the snake itself was big, Wilson said.

"If the snake had evolved the machinery that modern snakes have, it would have been able to take even bigger things," he said.

Sanejeh did have a key adaptation also found in modern snakes: an upper jaw that can move independently of the lower jaw.

This jaw structure would have allowed Sanejeh to wriggle, mouth first, over struggling prey in an alternating side-to-side motion familiar to anyone who has ever tried to squeeze into a tight pair of jeans. (See a picture of a python that's eaten a pregnant sheep.)

The snake may also have been capable of squeezing dinosaur eggs open to get to the hatchlings inside.

But because modern snakes tend not to attack inanimate objects, the researchers believe ancient snakes behaved similarly, so it's likely that the young dinosaur had already hatched before the snake arrived.

Young Dinosaurs Outgrew Snake Predators?

Due to the apparent victim's young age, the team couldn't determine the dinosaur's species. But they do know it was a sauropod—a giant long-necked plant-eater (sauropod picture). But what kind?

Previously discovered fossils suggest that titanosaurs—sauropods that grew to lengths of 65 feet (20 meters) or longer—roamed the region around the nest, leading the researchers to suggest the hatchling too was a titanosaur. (See "Eggs Hold Skulls of Titanosaur Embryos.")

The fossils of Sanejeh and its apparent prey were discovered in western India's Gujarat Province in 1984. After being mislabeled as containing only a hatchling sauropod, the fossil trove was separated before finally being reunited in 2004 and sent to the University of Michigan for study.

To avoid being eaten by snakes and other predators, sauropods, in general, probably underwent growth spurts in their early years, the study says. (Related: "Dinosaur-Size Spurt: T. Rex Teens Gained Five Pounds a Day.")

"By the time this sauropod was about a year old, we think it would have been out of the range of Sanejeh," Wilson said.

Dinosaur-Eating Snakes Not Surprising?

"The discovery is very interesting, and I think the study's conclusions are reasonable about the snake possibly feeding on hatchling dinosaurs," said Brad Moon, a herpetologist at the University of Louisiana at Lafayette, who was not involved in the new research.

Moon does think, though, that Sanejeh may have been attracted to the dinosaur nest for other reasons. For example, the snake might have simply been seeking shelter or pursuing some other animal, he said.

And while certainly spectacular, the revelation of a snake attack in progress is less than surprising, scientifically speaking, according to George Zug, curator emeritus of amphibians and reptiles at the National Museum of Natural History in Washington, D.C.

Though Zug agrees the new fossils are the first proof of snakes eating dinosaurs, he said the behavior wouldn't shock anyone familiar with the ways of modern snakes.

Snakes eat not only mammals and birds but also other reptiles, such as frogs and even other snakes, said Zug, who was not involved in the new study.

"So it's not out of the question that they would be preying on little dinosaurs."

Oldest T. rex relative identified

Sunday, January 23, 2011


The new addition to T. rex's clan is known from a 30cm-long skull uncovered during excavations in Gloucestershire in the 1900s.

The well-preserved fossil is held in London's Natural History Museum.

A British-German team has now uncovered evidence linking it to what may be the most famous dinosaur family of all.

The dinosaur, named Proceratosaurus, lived about 165m years ago, during the middle Jurassic Period.

The two-legged meat-eater would have measured about 3m long and weighed up to 60kg.

The palaeontologists used computed tomography (CT) techniques to generate a 3D image of the delicate skull to investigate its internal structure in meticulous detail.

Dr Angela Milner, associate keeper of palaeontology at the Natural History Museum, told BBC News: "This is a unique specimen. It is the only one of its kind known in the world."

She added: "It was quite a surprise when our analysis showed we had the oldest known relative of T. rex.

"Fossils collected a century ago can now be studied again with the benefit of much greater knowledge of dinosaurs from around the world."

Originally described in 1910 as a new species of Megalosaurus, the fossil was presented to the museum in 1942.

The skull had been unearthed during excavations for a reservoir close to Minchinhampton in Gloucestershire.

Dr Milner said that despite obvious differences between the skulls of Proceratosaurus and T. rex - such as their divergent sizes - the two shared many similarities.

"If you look at the animal (Proceratosaurus) in detail, it has the same kinds of windows in the side of the skull for increasing the jaw muscles," she told BBC News.

"It has the same kinds of teeth - particularly at the front of the jaws. They're small teeth and almost banana-shaped, which are just the kind of teeth T. rex has."

"Inside the skull, which we were able to look at using CT scanning, there are lots of internal air spaces. Tyrannosaurus had those as well."

Although the skull has attracted much interest because of its exquisite preservation, it has not been closely studied until now, thus, its link to the tyrannosaurs remained undiscovered.

"This is still one of the best-preserved dinosaur skulls found in Europe," said co-author Dr Oliver Rauhut from the Bavarian State Collection for Palaeontology and Geology in Munich.

A Lifeline for the Iberian Lynx

Friday, January 21, 2011




1.Only about 225 Iberian lynx remain in Spain and Portugal—an improvement over recent years but still too few for the species' survival.



2. Spring-footed Elanio, a year-old male in Spain’s Sierra de Andújar Natural Park, clears a "predator-proof" fence—just as wildlife managers intended. Designed to thwart other rabbit-eaters like fox and boar while letting cats up and over, the fence surrounds a feeding area seeded with prey.


3.Offering extra food is extreme but, right now, crucial: Lynx simply won’t breed if rabbits are scarce. And while one rabbit a day feeds a single lynx, a mother with cubs needs two or three.


4.His mother, Rappas, is still in charge for now, but Elanio will soon strike out and seek his own territory in the region’s forest, thicket, and scrub. A radio collar will enable staff of Lynx Life, a Spanish conservation group, to monitor him.


5.Lynx tend to be solitary after their first year and have been reported to stick to narrow ranges of about ten square miles—and to shun farmed or developed landscapes. But last year Lynx Life staff tracked a female on a nearly 200-mile foray. She successfully hunted on agricultural land—a hopeful sign of adaptability for this most critically endangered of cats.

Top 5 Most Rare Animals in the World

Tuesday, January 18, 2011


The Pinta Island Tortoise
The Pinta Island Tortoise is found in the Galapagos Islands. This particular tortoise was thought to be extinct nearly 30 years ago. A ranger happened to find one, and it is the last one known to exist alive.


The Baiji

The Baiji is also known as the river dolphin, and found outside of China. This dolphin is so rare, it is possibly extinct now. The dolphins numbers dwindled due to competing for it’s food with humans. Humans hunt fish, and that was the main source of their survival.



The Vancouver Island Marmot
This Marmot is found largely in British Columbia. Back in the year 2000, researchers discovered their numbers had fallen to approximately 75. Some have been taken to rehab facilities to try and mate them. If they can increase their numbers to 400 to 500, this will prevent their extinction.



Seychelles Sheath-tailed Bat
This particular bat is found just north of Madagascar. It is said there are fewer then 100 left on earth. If their numbers could increase to 500 or more, we may not lose them to extinction.



The Javan Rhino
The Javan Rhino is found only in Indonnesia and Vietnam. There is said to be only about 50 still alive in existance today. Again, humans are to blame for their low numbers and possible extinction. They were poached for their horns and supposedly used for medical reasons.

American Experience - "Dinosaur Wars"

Monday, January 17, 2011


The story of Edward Cope and O.C. Marsh, two men who began as friends, then became enemies over something as seemingly inconsequential as the discovery of dinosaur bones, is one of those quintessentially American tales that, nonetheless, isn’t widely known. The terrific book The Bonehunters’ Revenge, by David Rains Wallace, gets at some of what makes the story so fascinating, but this is a Paul Thomas Anderson movie just waiting to happen, a story of outsized personalities in outsized conflict over things that have been dead for millions upon millions of years. There’s treachery and backstabbing and people blowing things up and men smashing fossils with hammers, all the better for no one else to find them and get credit for the discovery. As renowned paleontologist Bob Bakker points out in the new documentary “Dinosaur Wars,” debuting tonight as a part of PBS’ American Experience series, there were enough bones for Cope and Marsh and a dozen others to have discoveries for years. Instead, the two men drove each other into ruin, over a hatred that took on a life of its own.

The greatest flaw of “Dinosaur Wars” is that it’s told in the now staid, traditional PBS documentary format (a format that’s used particularly often for histories). Photos and paintings of the past are accompanied by sonorous voiceover and sound effects meant to approximate the time. Occasionally, we’ll hear from a letter or period-appropriate document, usually read by the narrator. Talking heads will pop in from time to time to offer perspective and opinion. It’s a format that’s easily watchable, but it’s also a format that’s not horribly challenging to the audience, and it’s part of the reason PBS seems to give so many casual television viewers the hives. It wants to tell you a story (in many cases, like this one, a very interesting one), but it’s doing so in a way that constantly reinforces that you’re learning something. Instead of making the story come alive, it’s content to sit back and just tell you what happened.

But it’s not as though there’s anything wrong with that if the material is strong enough, as it is here. Cope and Marsh are fascinating characters, each just different enough from the other to drive each other a little nuts by mere proximity. The era, too, is fascinating, as the discoveries of long-dead prehistoric beasts ignite a kind of scientific fervor in the American mind. Now, finally, there’s a field where Americans can not only compete with Europe, but best Europe, which simply doesn’t have the same caliber of fossils. Combined with the way Darwin’s theory of evolution was taking root at the time, it created an exciting opportunity for the United States to be at the forefront of scientific discovery. (Darwin himself wrote to Marsh to praise the man for his work in laying out the evolution of the horse, using the fossil record.) And on top of it all, there’s still something exciting about the notion of dinosaurs, about giant reptiles that roamed the Earth millions of years ago and then all disappeared, leaving behind only their bones. It’s hard science, but it’s also something that can set the mind of a 5-year-old child racing with wonder.

Marsh, a Yale professor who used the discovery of prehistoric bones as a way to wrangle himself into a position of political power, mostly so he could keep Cope down, begins life as a part of a world of “gentleman naturalists,” a place where everyone is very conscientious of each other’s feelings and makes sure to not tread on each other’s toes when making discoveries. It’s doubtful this world actually ever existed, but Marsh certainly seemed to believe in it as a sort of Platonic ideal of how the natural sciences should be carried out. When he discovers a dinosaur in a quarry in New Jersey, a skeleton that kicks off the country’s fascination with the beasts, he’s only too happy to show the place of discovery to his friend, Cope. But Cope has ulterior motives and makes a deal with the quarry owner to send all future discoveries to him and him alone, a business deal that violates Marsh’s sense of science as a gentleman’s game and kicks off the bitter rivalry between the two.

Marsh is a loner, living in a rambling manse in New Haven, Conn., and using his ties to the university to finance ever-more elaborate expeditions into the dangerous American West to find grander and grander specimens. He’ll return to New Haven to show off his discoveries and entertain, but his truest love is the pursuit of new discoveries, leaving him without a family for all of his life. Cope, meanwhile, is capable of great tenderness toward his own family and a pacifist Quaker who refuses to carry a gun when he ventures into hostile territory alone in the immediate wake of Custer’s loss at Little Bighorn. But he’s also an irascible man, prone to fits of anger, particularly when directed at Marsh. The two’s competition drives most other paleontologists, including mutual friends, out of the field, and they take to finding any means necessary to lock each other out of new finds, right down to smashing up bones they can’t immediately cart away from the dig.

There’s enough material in the feud between Marsh and Cope to fuel several documentaries, so it’s a natural consequence of American Experience’s one-hour running time that what’s here feels slight. There’s little time devoted to the friendship between Marsh and Cope, but the documentary also skirts over some of the nastier things the two did to each other, such as when Marsh used his position within the U.S. Geological Survey to effectively end Cope’s career, ruining him and even tearing his family apart. The narrative is so diffuse and spread out over so many years and so much geographical territory that there’s simply no way to get all of it into a single hour-long episode satisfactorily. Furthermore, the film tries to incorporate so many characters that it can only glancingly define most of them. (Cope’s family, in particular, gets short shrift, though they were interesting people in their own right.)

But all of that is one of those things that’s a natural problem with the one-hour TV documentary format. And if the story is strong enough, those concerns can usually be washed away. The story here is definitely strong enough to keep viewers watching, propulsive in a way this kind of TV documentary-making rarely is. By the time Cope and Marsh are driving each other to early graves, both of their careers and fortunes ruined, the story has taken on a kind of tragic heft, and virtually none of it is due to the filmmaking, which stays in the traditional, safe realm it always exists in. What happened here was sad enough on its own to give this story the power it needs to transcend the problems that come from trying to fit it into an hour and into this format. But do please bring on that movie and very soon.

New Early Dinosaur Fossils Shift Family Tree


Scientists have discovered a four-foot-long, meat-eating dinosaur, with serrated teeth and long finger bones, that roamed the earth some 230 million years ago. The fossils are among the earliest dinosaur bones ever found, and the finding, which was published Thursday in the journal Science, has shaken up the creature's family tree.

The bones of the tiny dinosaur, which scientists have named Dawn Runner, or Eodromaeus murphi , were found encased in rock chunks in an arid Argentinian valley, known as "Valley of the Moon."

"It's significant for dinosaur origins because it's a relatively complete skeleton, and there's more than one of them," said Sterling Nesbitt, a paleontologist from the University of Washington, who specializes in early dinosaurs. "There are many questions, and the only way they can be answered is through new material."

Dawn Runner roamed the earth during the late Triassic era, before dinosaurs rose to dominance, when continents with vast desert belts were shoved together and primitive mammals and early crocodiles were abundant. It had grasping hands, walked on two feet and had air sacks in its neck vertebrae like a bird. It was svelte and scrappy, "not a big chunky bruiser animal by any means," said Mark Norell, chairman of paleontology at the American Museum of Natural History in New York City. "It was sort of the Kate Moss of the dinosaur world."

Paul Sereno from the University of Chicago was one of the two lead authors, along with Ricardo Martinez of the National University of San Juan in Argentina.

"It was a scrappy meat-eater that would come at you, and you'd be twisted around before you knew which way it went," Sereno said. "A 10 to 15-pound ball of energy. And it's got canines that are definitely for slicing and dicing meat."

Using bones from different dinosaurs, the paleontologists were able to piece together almost an entire skeleton and with it, more evidence of the beginnings of the dinosaur lineage. Scientists have identified the animal as a theropod, which means it may be a distant ancestor to both Tyrannosaurus Rex and modern birds.

The discovery has also led to the reclassification of the dinosaur, Eoraptor, which was discovered in the early 1990s by the same team. Eoraptor was originally thought to be a theropod, but this study redefines it as sauropod, an herbivore.

The finding may be controversial, Nesbitt, says, "because everyone has previously found Eoraptor to be a carnivorous dinosaur. It solves a couple questions, but creates a lot more to be answered." But, he adds, the paper puts forward convincing evidence.

"For me, the take home message is to realize that this is a good approximation of a primitive dinosaur," Sereno says. "Great things come from small beginnings like this. And...if you went back 230 million years ago, you'd likely be eaten by a crocodile. Dinosaurs would come and pick your bones."

Fresh dinosaur bones found

Wednesday, January 12, 2011


The lady was highly skeptical. This guide, who moments before had been discussing animal ecology and evolution, found when confronted with news of the new discovery—that she simply could not believe it. She could not accept that fresh (not permineralized, meaning unfossilized) dinosaur bones had been found in Alaska. Such bones could never have lasted 70 million years, she said.

Unlikely or not, it is a fact that such bones have been found. However, whether they could have lasted in that condition more than a few thousand years is a matter which demands attention.

In 1987, while working with scientists from Memorial University (Newfoundland, Canada) on Bylot Island, just east of the northern tip of Baffin Island, a young Inuit (Canadian Eskimo) picked up a bone fragment. It was identified within days as part of the lower jaw of a duckbill dinosaur and proclaimed to the world as such.1

The story was different however in north-western Alaska. In 1961 a petroleum geologist discovered a large, half-metre-thick bone bed. As the bones were fresh, not permineralized, he assumed that these were recent bison bones. It took 20 years for scientists to recognize duckbill dinosaur bones in this deposit as well as the bones of horned dinosaurs, and large and small carnivorous dinosaurs. Presently William A. Clemens and other scientists from the University of California at Berkeley and the University of Alaska are quarrying the bone bed.2

How these bones could have remained in fresh condition for 70 million years is a perplexing question. One thing is certain: they were not preserved by cold. Everyone recognizes that the climate in these regions was much warmer during the time when the dinosaurs lived. In central Alberta abundant plant remains indicate that the climate here was semi-tropical. It is standard geological interpretation that even after the dinosaurs died out, the entire planet was much warmer, perhaps as the result of high levels of carbon dioxide in the atmosphere. Why then did these bones not decay long ago?

Similar perplexing questions can be asked about the ‘frozen forest’ found even further north on Axel Heiberg Island in the Canadian Arctic, less than 1,200 kilometres from the North Pole.

Geologists claim that these forest remains are about 45 million years old. Nevertheless, the wood and leaf debris are astonishingly well preserved. The plant material is not petrified. The logs are still wood which can be sawn and burnt. The leaf debris and cones include some specimens recognizable as dawn redwood.3 This tree does not presently grow even as far south as Alberta, except in conservatories like the Muttart Conservatory in Edmonton and the Palaeoconservatory at the Royal Tyrrell Museum in Druinheller.

The temperate forest, preserved in the Arctic, seems to have been particularly lush, with 50-metre trees with trunk diameters of two metres, crowded only about six metres apart.

These recent developments are certainly food for thought. It is undeniable that fresh dinosaur bones have been found. Items have appeared in the secular literature saying exactly that. It is also evident that preservation in the fresh state for even one million years is highly unlikely.

The obvious conclusion is that these bones were deposited in relatively recent times. This bone bed is stunning evidence that the time of the dinosaurs was not millions of years ago, but perhaps only thousands. It is time geologists recognized the implications of their own data.

New dinosaur bones found in Russia's southeastern region


New dinosaur bones have been found at an excavation site in Russia's southeastern region of Primorsky Krai, the Vostok-Media news agency reported Friday.

"While removing bones of an olorotitan from Kundursky excavation site, we spotted a tooth of a carnivorous dinosaur stuck between the caudal vertebrae of the olorotitan," said Ivan Bolotsky, a junior research assistant at the Russian Academy of Sciences' Institute of Geology and Natural Resource Use.

Paleontologists believe the dinosaurs were killed by a mudslide because the bone fragments were buried in solidified mud and stone, according to the report.

The paleontologists have been digging up bones of dinosaurs at the excavation site for two years, inch by inch removing soil from the finds.

Yuri Bolotsky, chief of Paleontology Laboratory at the Far Eastern regional branch of the Russian Academy of Sciences, said: "The dinosaurs have been preserved to such an extent that the orifices, outlets of cranial nerves and blood-vessels remained intact. That means we can analyze the brain structure of these animals."

Scientific evidence to date shows the bones of the last dinosaurs in Asia are buried there. But scientists cannot say how many as the bone bed stretches for about 30 km.

Fossils Excavated At Colorado National Monument

Monday, January 10, 2011


Dinosaurs Fossils are not exceptional for paleontologists to dig up on the Colorado National Monument, as this place is showing some big finds in fossils. Paleontologists have discovered two different fossilized tracks that are not bigger than a quarter but they are printing a rare scene for researchers and creating quite a stir.



Dr. John Foster (paleontologist) says that "Tracks are evidence of a living animal going about its business and these prints of a lizard and some turtles are 150 million years old. They are generations that were lived in the shade of the bigger dinosaurs like Stegosaurs and Brachiosaurus.



Dr. George Callison says - Some shows more than one turtle heading in the same direction that gives raise to speculation that maybe we are looking at a herd of turtles. Often, small animal tracks are swept away long before they're preserved and they are rare to find in the Morrison Formation.



However, these findings play an important role in finding how an animal like the turtle lived and fossils will be display at the Colorado National Monument's visitor center until October 22nd.

New Research on Tyrannosaurus Rex


The status of the Tyrannosaurus rex, previously the badass of the dinosaur world — just got a modest seedier; new research shows it took part in cannibalistic behavior.

The Canadian and U.S. paleontologists reveals facts that showing the Tyrannosaurus rex ate members of its own species, a report published Friday on the online science journal.

A few years ago, Yale University researcher Nick Longrich gave additional reflection to some large teeth marks he had found on a dinosaur bone exposed in Montana.

He said it dawned on him the bite marks had to come from a Tyrannosaurus rex, since it was the only large carnivore in North America 65 million years ago, the era the fossil was known to have come from. It also became apparent the bone itself was from a Tyrannosaurus rex.

Succeeding examinations of dinosaur bones from numerous museum collections exposed additional bites, signifying Tyrannosaurus rex-on-Tyrannosaurus rex eating action was quite common.

"If you think about the way these big carnivores are, they're designed to eat other big animals, and they are also big animals," Longrich said.He noted that many animals alive today, such as alligators and bears, are known to eat each other. "Modern animals are cannibalistic quite often."

Tyrannosaurus Rex AteTyrannosaurus Rex At Jurassic Period


Tyrannosaurus Rex was the undisputed king of the "dinosaurs">dinosaurs. They eat each other. The Yale researcher Nick Longrich found vast gouges in the bone of a Tyrannosaurus rex.

He said, “They’re the kind of marks that any big carnivore could have made,” said Longrich, “but Tyrannosaurus rex was the only big carnivore in western North America 65 million years ago.”

Longrich unremitting to investigate for other signs of Tyrannosaurus rex cannibalization and excavated a total of three foot bones and one arm bone that showed signs of being chobbled on by another Tyrannosaurus rex, which, allowing for the amount of fossils we have represents a important proportion.
“It’s surprising how frequent it appears to have been,” Longrich said. “We’re not exactly sure what that means.”

The symbols on the bones are convincingly the result of feeding, but whether the cannibalization was a result of the behemoth’s skirmishing each other to the death, or simply that of scavenging for food, is unidentified.

“Modern big carnivores do this all the time,” he said. “It’s a convenient way to take out the competition and get a bit of food at the same time.”

These conclusions are an unlooked-for clue into the lives of one of the more hidden dinosaurs. “They were some of the largest terrestrial carnivores of all time, and the way they approached eating was basically unusual from modern species,” Longrich said. “There’s a big mystery around what and how they ate, and this research helps to uncover one piece of the puzzle.”

India Asteroid Killed Dinosaurs, Made Largest Crater?

Sunday, January 9, 2011


For decades one of the more popular theories for what killed the dinosaurs has focused on a single asteroid impact 65 million years ago.

A six-mile-wide (ten-kilometer-wide) asteroid is thought to have carved out the Chicxulub crater off Mexico's Yucatán Peninsula, triggering worldwide climate changes that led to the mass extinction.

But the controversial new theory says the dinosaurs were actually finished off by another 25-mile-wide (40-kilometer-wide) asteroid. That space rock slammed into the planet off the western coast of India about 300,000 years after Chicxulub, experts say.

"The dinosaurs were really unlucky," said study co-author Sankar Chatterjee, a paleontologist at Texas Tech University in Lubbock.

Chatterjee thinks this second asteroid impact created a 300-mile-wide (500-kilometer-wide) depression on the Indian Ocean seafloor, which his team began exploring in 1996.

His team has dubbed this depression the Shiva crater, after the Hindu god of destruction and renewal.

"If we are correct," Chatterjee said, "this is the largest crater known on Earth."

Dinosaur-Killer Asteroid Boosted Volcanoes?

The Shiva asteroid impact was powerful enough to vaporize Earth's crust where it struck, allowing the much hotter mantle to well up and create the crater's tall, jagged rim, Chatterjee estimates.

What's more, his team thinks the impact caused a piece of the Indian subcontinent to break off and drift toward Africa, creating what are now the Seychelles islands (see map).

The Shiva impact may also have enhanced volcanic eruptions that were already occurring in what is now western India, Chatterjee added.

Some scientists have speculated that the noxious gases released by the Indian volcanoes, called the Deccan Traps, were crucial factors in the dinosaurs' extinction.

Jurassic Park


With Jurassic Park, Steven Spielberg recalled from extinction the greatest creatures our planet has ever known. "My interest is in making a good movie that honors the existence of dinosaurs," Spielberg said during filming of the 1993 biogenetics adventure, which would become the highest grossing motion picture of all time and win three Academy Awards® for its ground-breaking visual and sound effects.

To resurrect these ancient and powerful species who ruled the world for 165 million years, the director and his team of special effects wizards embarked on a three-year journey of discovery, creating new technologies, transforming old ones and ushering filmmaking into the 21st Century.

In May of 1990, Universal Pictures obtained the galleys of best-selling author Michael Crichton's upcoming book Jurassic Park, and within a matter of hours, the studio was intently negotiating to purchase the book on behalf of Steven Spielberg.

"It was one of those projects that was so obviously a Spielberg film," recalls producer Kathleen Kennedy, who has closely collaborated with the filmmaker for 18 years. "If you look at the body of Stevens work, he is very often interested in the theme of extraordinary things happening to ordinary people."

As Crichton began adapting his book about a theme park for genetically engineered dinosaurs into a feature-length screenplay, Kennedy and Spielberg began to recruit the behind the scenes team that would lay the creative foundation for Jurassic Park. First on board was production designer Rick Carter, who started work with a group of illustrators and storyboard artists to translate Crichtons words into cinematic images.

The next challenge was to find an all-star effects team that would bring the dinosaurs to life. Stan Winston was contacted to create the live action dinosaurs, with Phil Tippet serving as dinosaur supervisor, Michael Lantieri handling special dinosaur effects and Industrial Light & Magics Dennis Muren in charge of full motion dinosaurs. Their achievements, individually and collectively, had included box-office successes from Star Wars to Teminator 2: Judgment Day, and they would eventually receive an Oscar for best visual effects for Jurassic Park.

Meanwhile, work continued on the screenplay, beginning with Michael Crichtons first draft. Later, screenwriter David Koepp was brought in on the project and shared screen credit with Crichton.

Casting was a relatively short process, capped by the signing of Richard Attenborough (whose acclaimed work as a film director had distracted him from acting since 1979) for the pivotal role as Jurassic Park developer John Hammond. Rounding out the talented ensemble cast were Sam Neill as Dr. Alan Grant, a renowned paleontologist who is asked to inspect the park; Laura Dern as his colleague, Dr. Ellie Sattler; Jeff Goldblum as a brilliant but eccentric mathematician whose chaos theory explains the dangers inherent in the project; and Ariana Richards and Joseph Mazzello as Hammond's young grandchildren.

In order to tackle the scope and breadth of the project ahead, Winston designated a group of teams that included both artists and engineers. To give you an idea of each team's complex responsibilities, meet "Team rex," which consisted of 12 operators performing widely varying functions. Constructed from a frame of fiberglass and 3000 pounds of clay, the 20 foot tall T-rex was covered with a durable yet delicate latex skin and then painted by a team of artists who blended a rich palette of colors to bring his body to life. The T-rex was then mounted on a "dino-simulator," an imaginative mechanism inspired by hydraulic technology and based on a traditional six-axis flight simulator used by the military. On this motion-based foundation, both the platform and the T-rex could be actuated through a computer control board.

When "Jurassic Park" began principal photography on the island of Kauai on August 24, 1992, it had been exactly two years and one month since the start of pre-production. The lush green resort-land near Lihue was an ideal setting for the Jurassic Park exteriors, but after three weeks of filming under the tropical sun, a real-life drama overshadowed the movie.

Hurricane Iniki was fast approaching Kauai, and the crew was asked by the hotel to pack their suitcases and fill their bathtubs with water in case of future power and water shortages. Next, they were instructed to pack a day bag and meet in the ballroom of the hotel on the basement level.

By 9:00 a.m. the storm was headed straight for the island. Kathy Kennedy recalls, "We started pulling all our supplies into the ballroom, and the camera crew was quickly packing their things in the trucks. But if you're going to be stranded with anyone, be stranded with a movie crew," says Kennedy. "We had generators for lights, and plenty of food and water. We were self-sustaining because we moved around on location all the time."

Camped out in rows of chaise lounges on the ballroom floor, the cast and crew heard the winds pick up at about 4:00 p.m. and rumble by at almost 120 mph. "It sounded like a freight train roaring past the building," recalls the producer.

When water seeped into one end of the ballroom, the crew huddled on the other side of the room. But at 7:30 p.m., Kennedy and Gary Hymes, the stunt coordinator, stepped outside into silence. "It was the eeriest thing I had ever seen," recalls Kennedy. "Here we were that morning on a beautiful tree-lined street adjacent to a golf course, and now virtually every single tree had been flattened."

Although the company had scheduled one more day of filming, the sheer force of Iniki literally struck all the sets. There was no power or working phones on the island, so at dawn the next morning, Kennedy jogged two miles to the airport to explore their options.

"The destruction in the airport was unbelievable," she recalls. "All the windows were blown out in the terminals, and the buildings were full of palms, trees, sand and water. Every single helicopter had been tipped on its side."

Thanks to her relentless efforts among airport and military personnel in Lihue, Kennedy was able to hitch a ride to Honolulu on a Salvation Army plane and began organizing from a pay phone. Over the next 24 hours, she not only coordinated the safe return of the company, but also arranged for more than 20,000 pounds of relief supplies to be transported from Honolulu and Los Angeles into Kauai.

Upon its return to Los Angeles, "Jurassic Park" resumed production at Universal Studios. Stage 24 had become the industrial-size kitchen for Jurassic Park's Visitors Center and it was being visited by two predatory Velociraptors. While Winston's team manipulated every moving part of the full size Raptor from head to tail, actors Ariana Richards and Joseph Mazzello cowered in the corner, deep into their characters of two young children who are trapped in their worst nightmare.

From there, the company packed up and moved to Red Rock Canyon State Park, at the west end of the Mojave Desert. Chosen for its similarities to a Montana dinosaur dig site, Red Rock played host to actors Laura Dern and Sam Neill, both of whom were coached by one of the country's premier paleontologists, Jack Horner. As a professor at the University of Montana and curator of paleontology at the Museum of the Rockies in Bozeman, Horner was a valued member of the crew and the official paleontology consultant.

Returning to Stage 27, the Company began a complicated sequence following a confrontation with the mighty T-rex, who had effortlessly picked up a Ford Explorer and hung it on the branches of a gigantic gnarled tree. Rigged by Michael Lantieri's team and suspended on steel cables, the car slowly slips from branch to branch until it falls to the ground with a reverberating crash. By the end of the shoot, the tropical jungle on Stage 27 had been re-dressed for three additional scenes: an early morning visit from a Brachiosaurus, a surprise attack on Muldoon (Bob Peck) and Dennis Nedry's (Wayne Knight) encounter with a Spitter.

Stage 28 housed the heart of Jurassic Park; a computer control room and dinosaur hatchery. Headed up by Michael Backes, computer effects designer, the Control Room was headquarters for almost a million dollars in high-end equipment, on loan from such industry leaders as Silicon Graphics, SuperMac, Apple and Thinking Machines.

When Nedry's sabotage results in Control Room chaos, the audience will simply watch the display screens in order to understand the problems that face the park visitors who are on the royal tour.

By size and scope, the most memorable "Jurassic Park" set was perhaps the Visitor's Center constructed on Stage 12, but it was closely rivaled by the T-rex Paddock, located on one of the largest sound stages at Warner Brothers Studios. Lantieri and his crew built the riggings that mobilized the 3000 lb. dinosaur, who along with his fellow actors, worked long, hard hours in the wind, rain and mud.

The film's climactic finale was filmed on Stage 12, in Jurassic Park's enormous Rotunda, which, according to the script, is still under construction. As John Hammond escorts his visitors into the main lobby, the first thing they see are two gigantic dinosaur skeletons displayed in the middle of the Rotunda.

Constructed by Toronto-based Research Casting International, the museum-quality pieces are full-size re-creations of a T-rex, which is approximately 40 feet long, and an Alamosaurus, which measures 45 feet long.

As the cast and crew lifted their glasses in a champagne toast on the final night of filming, a weary but enthusiastic Spielberg announced that "Jurassic Park," an ambitious project which had been two years in the planning and four months before the cameras, had finished on budget and 12 days ahead of schedule.

Dinosaur Extinction - Compelling New Theory

Thursday, January 6, 2011


Dinosaur Extinction: Another Theory
Dinosaur Extinction is a hot topic for debate. New theories for the catastrophe that killed the dinosaurs are presented every couple of years. We have viewed the evidence and have decided to present our own theory.

Dinosaur Extinction: The Premise
Dinosaur extinction -- Most scientists believe that dinosaurs went extinct about 50 to 65 million years ago. Most scientists agree that man’s conception of dinosaurs has been limited to the past 180 years or so (the word itself wasn’t even coined until 1841). Therefore, if we discovered evidence of man’s knowledge of (or coexistence with) dinosaurs during the last couple of centuries, “science” (as we know it) would be turned upside down.

Dinosaur Extinction: The Evidence
# Human & Dinosaur Fossils. Human bones and tools coexist in the same fossil layers as dinosaur bones in Texas and the Dakotas.
# Human & Dinosaur Footprints. Footprints of dinosaurs, humans and other mammals coexist in the same fossil layers in Texas and New Mexico.
# Native American Petroglyphs. Cave and cliff drawings in Utah and Colorado crudely depict certain dinosaur species (dated from 400 A.D. to 1300 A.D.).
# Ica Stones. Ceremonial burial stones discovered in Ica, Peru depict numerous species of dinosaurs, some in activities with man (dated from 500 A.D. to 1500 A.D.).
# Acambaro Figurines. Ceramic and stone figurines discovered in Acambaro, Mexico represent many species of dinosaurs (dated from 800 B.C. to 200 A.D.).
# Dragon Accounts. China, Europe and the Middle East share similar accounts of “dragons” and other beasts. Some cultures revered these creatures. For instance, records of Marco Polo in China show that the royal house kept dragons for ceremonies. In other cultures, it was a great honor to kill these beasts. There are numerous records of warriors killing great beasts in order to establish credibility in a village.
# Behemoth, Leviathan and the Dragons of the Bible. Job writes of great creatures, Behemoth and Leviathan, nearly 4000 years ago. Although more recent Bible translations use elephant, hippo or crocodile instead, the original Hebrew does not allow for these interpretations. The word “dragon” (Hebrew: tannin) is used numerous times in the Old Testament, and most directly translates as “sea or land monsters.”
# Gilgamesh, Fafnir, Beowulf and other Legends. Many famous legends, including the mythology of Egypt, Greece and Rome, include specific descriptions of dragons and other dinosaur-like creatures.
# Dragons in Ancient Art. Dinosaur-like creatures are featured on Babylonian landmarks, Roman mosaics, Egyptian burial shrouds, and many other pieces of art throughout the ancient world.
# Current Legends & Discoveries. There is a huge and credible legacy of sea, lake and swamp “monsters,” even to this day.

Dinosaur Extinction: The Theory
Dinosaur Extinction is a recent phenomenon. Many of the great sea and land monsters went extinct in a global flood about 4400 years ago. Some of these creatures survived and inhabited earth with man, until they too went extinct as man killed them for sport, safety, and expansion (like bison in the Western U.S.). We know this theory is revolutionary to many! However, we must admit -- it’s not original. In fact, it's really not a theory at all. It’s based on the established truth of the Biblical record -- a record that’s not dependant on mankind’s ever-changing view of science and reason. We absolutely encourage you to carefully examine the evidence for yourself!

The extinction of the dinosaurs


Dinosaur extinction is still a major enigma of earth history. In this review article, extinctions in the geological record will be briefly mentioned. Many of the imaginative theories for the extinction of the dinosaurs will also be presented.




Within the uniformitarian paradigm, the meteorite impact theory, once considered ‘outrageous’, now is the dominant theory. However, the volcanic theory is still believed by a majority of palaeontologists. Both theories have their strengths and weaknesses.



The unscientific behaviour of those involved in the meteorite paradigm change will be briefly explored. Evidence that the dinosaurs died in a cataclysm of global proportions will be presented, such as the huge water-laid dinosaur graveyards found over the earth.



Occasional monospecific bone-beds and the rarity of fossils of very young dinosaurs suggest a catastrophic death and burial. The billions of dinosaur tracks recently discovered provide testimony to unusual, stressful conditions. Nests, eggs, and babies are a challenge to a Flood model, but there are enough unknowns associated with the data that solid conclusions are difficult to draw.



The part that impacts and volcanism play in a Flood paradigm will be briefly discussed. The question of whether the K/T boundary and the extinction of the dinosaurs should be considered a synchronous event within the Flood will be considered.
