Thousands of dino fossils discovered in Spain

Sunday, December 12, 2010

The recent spectacular discovery of 70-million-years-old dinosaur-fossils supports that Europe, toward the end of the dinos’ reign on Earth, was much richer in dinosaurs than previously thought.

8000 fossils of eight different dinosaur species have been discovered. The bone yard was found during the construction of a high speed rail track near Cuenca of eastern Spain. The excavating team believes that this grave yard might be the largest and most diverse dinosaur site of whole Europe. Limb bones, skull remains and partially intact skeletons including fragile ribs were among the well-preserved fossils found.

At least three types of titanosaur have been identified so far which suggests that these dominant plant-eaters of the period were massive, long-necked sauropods and they were among the largest animals ever to have walked the Earth. Fossils of 6foot long carnivorous dinosaurs, called dromaeosaur, were also uncovered from the site. According to the excavating team, fossil creatures were found grouped together in clay and silt sediments and it seems a river created that grave yard. Jose Luis Sanz, in charge of the team, said:

Flooding maybe was responsible for the accumulation of carcasses.

Further investigation suggests that the fossils date to some four million years before the dinosaurs went extinct is refocusing these dinosaur ecosystems. Sanz also added,

This site seems to indicate, as some [other] scientists have suggested, that dinosaurs were at their maximum level of diversity during the K-T biotic crisis (or Cretaceous-Tertiary event).

Many smaller fossils still await examination in the lab. The total excavation was named as Lo Hueco and it will be continued in next spring over the rest of the site.
