Field notes

About Agilisaurus

What it was like

Agilisaurus was a small, two-legged plant eater about 1.5 meters (5 feet) long. It had long legs, a long tail for balance and leaf-shaped teeth. It was probably quick on its feet, which was its best defense.

Its world

It lived in the Jurassic in what is now China. Its bones come from the Shaximiao Formation, where it shared the land with the long-necked Shunosaurus and the early stegosaur Huayangosaurus.

How it was found

Peng named Agilisaurus in 1990 from one nearly complete skeleton.
