(CNN) Paleontologists in Argentina have identified a previously unknown species of dinosaur that would have used its huge claws, powerful bite and keen sense of hearing to hunt prey in Patagonia 80 million years ago. The fossilized remains of Llukalkan aliocranianus include a superbly preserved and uncrushed braincase and were unearthed in the Bajo de la Carpa Formation in Argentina. Llukalkan means "the one who causes fear" in the language of the indigenous Mapuche, and aliocranianus is Latin for "unusual skull." An artist impression of what Llukalkan aliocranianus may have looked like by Jorge Blanco. It means that Llukalkan likely heard differently, and probably better, than other abelisaurids -- more similar to the hearing of a modern-day crocodile.
