Field notes

About Jeholosaurus

What it was like

Jeholosaurus was a small, two-legged plant eater. It had large eyes, a short snout, and teeth of two kinds: pointed teeth at the front of its jaws and leaf-shaped teeth at the back. It may have eaten a mix of plants and small animals.

Its world

It lived about 126 to 120 million years ago, in the Early Cretaceous, in what is now China. Its bones come from the Yixian Formation, a land of forests and lakes shared with the small horned Psittacosaurus, the feathered Sinosauropteryx and the big feathered tyrannosaur Yutyrannus.

How it was found

Xu and colleagues named Jeholosaurus in 2000. Several skeletons of young animals have since been found.
