Two new species of dinosaur discovered by accident

After 75 years during a museum remain in Ottawa, in Canada, two dinosaur fossils have now been identified as being new. Or rather, as never having been identified previously.

"We have already discovered most species, but apparently there are many undiscovered," explained Nick Longrich, a paleontologist at the University of Bath in the United Kingdom. "We're still just digging the surface", metaforizou.

The two new species â€" the pentaceratops aquilonius, small cousin, triceratops and other of the genus kosmoceratops-lived in North America until the end of the Cretaceous, there are 75 million years ago.

Second Longrich, these dinosaurs will have migrated from a part of North America to another, diverging species. And only the competition among them has avoided that dinosaurs moved between the northern and southern regions of the continent.

"With the dinosaurs of the Cretaceous we see many large species in one habitat. They also tend to be very regional: as we pass from one to another habitat we have a completely different view of species "continued. The discovery was published in the September issue of the journal Creataceous Research.
