Psittacosaurus, an herbivore that lived some 120 million years ago, walked on two legs and would have reached about half a meter in height.
To figure out where Psittacosaurus may have lived, Vinther's team crafted two life-size models of the dinosaur.
The Psittacosaurus genus existed around 120 million years ago, in the early Cretaceous period, in present-day China, coinciding with the time when several large predators also roamed the region.
Our Psittacosaurus was reconstructed from the inside-out.

The colour pattern suggested Psittacosaurus (pronounced sit-TAK-ah-sawr-us) lived in a forest environment with diffuse light from a dense canopy of trees, the researchers said.
The investigation focused on dinosaurs in the genus Psittacosaurus
, a word that comes from the Greek for "parrot lizard.
, the "parrot dinosaur" is known from more than 1000 specimens from the Cretaceous, 100 million years ago, of China and other parts of east Asia.
Some of the bones from the baby Psittacosaurus
were only a few millimeters across, so I had to handle them extremely carefully to make useful bone sections," Zhao said.
Visitors will meet Mamenchisaurus, a huge plant-eater with the longest neck of any animal in history; the unicorn-like duck-billed Tsintaosaurus; and a miniature ceratopsian called Psittacosaurus
, or parrot lizard; Sinosauropteryx and Caudipteryx, two of the feathered dinosaurs that have electrified the world of paleontology--and who can resist the sight of a Monolophosaurus locked in mortal combat with a Tuojiangosaurus?
Not to put too fine a point on it, but there is also a problem with the Psittacosaurus
in the background of the illustration.
According to a report in the Telegraph, the new dino, named Psittacosaurus
gobiensis, meaning 'parrot lizzard', is thought to have lived about 110 million years ago.
Comparisons with known fossils suggest that those fragments belong to a hand-length hatchling of a Psittacosaurus
, a common plant-eating dinosaur that grew to a length of around 2 meters.
This find indicates that Triceratops juveniles congregated in small herds, a social behavior increasingly identified in other dinosaur groups, such as Psittacosaurus
, a small cousin of Triceratops that lived in Asia.
