New light on megaraptorids

A new megaraptorid dinosaur species discovered in Patagonia Desert may help scientists find out evolutionary origins of the megaraptorids represented by Megaraptor, Orkoraptor and Aerosteon. The Patagonian region of Argentina has previously proven to be rich in fossils from the late Cretaceous epoch, including a number of megaraptorids whose carnivorous diet gave rise to their name meaning ‘giant thieves’.  The new species discovered in Sierra Barrosa of Patagonia represents one of the most complete megaraptorids found, with an unusually intact braincase. Researchers found that the new species shared many features with the other species.
