Field notes

About Gasosaurus

What it was like

Gasosaurus was a mid-sized theropod about 4 meters (13 feet) long, a two-legged meat eater. Only part of its skeleton is known, and no skull, so its looks and exact place on the family tree are uncertain.

Its world

It lived in the Jurassic, in what is now China. It comes from the Shaximiao Formation, home to the long-necked Mamenchisaurus and Shunosaurus, the stegosaurs Huayangosaurus and Tuojiangosaurus, and the larger predator Yangchuanosaurus.

How it was found

Dong and Tang named Gasosaurus in 1985. Its unusual name honors the gas company whose work uncovered the fossils.
