Parrot-like Dinosaur Found in Mongolia

The creature, Psittacosaurus gobiensis whose name means “parrot lizard”, is thought to have lived about 110 million years ago.

Psittacosaurs are note for being the most species-rich dinosaur genus with at least nine different species, including the latest found in the Gobi Desert, a famous dinosaur graveyard.

Features of the dinosaur included a near perfect skull, strong jaw muscles and a powerful biting and crushing bill - showing that it evolved structures like those in today’s parrots.

The three feet long psittacosaurs may also have had a diet dominated by nuts and seeds, owing to the presence of many large stomach stones, according to the findings published in Proceedings of the Royal Society B: Biological Sciences.

Prof Paul Sereno, a Biologist from the University of Chicago, said analysis of its skull showed it chewed its food in a similar way to modern parrots.

“These and other features, along with the presence of numerous large stomach stones, suggest that psittacosaurs may have had a high-fiber, nut eating diet,” he said.

Its short snout just a third of the skull length was different to most dinosaurs, giving the skull its parrot-esque profile.

They ate nothing but plants and walked normally on two legs but could reach the ground with their three-fingered hands.

They were good runners and were extremely successful in Asia about 100 million years ago, during the Cretaceous Period.

“Psittacosaurs are all relatively small in body size, ranging from one to two meters in body length. Their geographic range is limited to central Asia, and their temporal range may be as narrow as 10-20 million years in the mid Cretaceous,” said Prof Sereno.

It is a member of the Ceratopsia group of herbivorous, beaked dinosaurs, which also include the more famous Triceratops.
