Dinosaur fossils from southern Alberta have shown that some of the creatures that roamed the seas about 74 million years ago, could only eat something that classifies life flourish.
A research group improved the remaining two samples prognathodon, often described as marine reptiles of six meters in length is also directly related to lizards, 30 km south of Lethbridge in 2002 and 2007. The newly exposed fossils believed to be the world's only fossil of this species is found both skulls and skeletons in one piece.
The study was conducted by the Royal Tyrrell with Takuya Konishi and Donald Brinkman, who thought the dinosaur fossils in an attempt to loosen a puzzle really primitive. When the investigation has sealed the courage to prognathodon others, also part of the family mosasaurs, researchers unveiled a large fish of about 1.6 meters long, 60 inches of a turtle coverage, and this they describe as a potential ammonite jaw. "What was important was prognathodon was not only able to feed on fish, like most mosasaurs did, but it can also eat turtles," said Konishi. "He told us he was able to piece of meat with his teeth, and it can also chew hard-shelled animals." Thus, recent studies indicate prognathodon was "omnipotent" in its marine food chain, Konishi also added more off.
The discovery will help researchers to put together again as part of an evolutionary mystery of research has shown that, although the heads prognathodon were huge, their torsos turned out to be much smaller. "Regardless of its enormous head, the skeleton was not large, was too thin," said Konishin. The latest study showed that the mosasaurs heads' were surrounded by creatures first to develop parts of the body, and was adapted as the reptiles could expand their eating habits, especially by improving the survival rate of interest, and a significant thrive in the upper part of their ecosystem.
