About Coloradisaurus

What it was like

Coloradisaurus was a plant eater about 4 meters (13 feet) long, from the long-necked line that later produced the giant sauropods. It had a small head with large eyes, a long neck and strong hands with big thumb claws.

It was a relative of Massospondylus and Lufengosaurus.

Its world

It lived in the Late Triassic in what is now northwestern Argentina. Its bones come from the Los Colorados Formation, where it shared the land with the plant eaters Riojasaurus and Lessemsaurus and the crested hunter Zupaysaurus.

How it was found

Lambert named Coloradisaurus in 1983. Two finds are known, one with a well-preserved skull.
