Field notes

About Erlikosaurus

What it was like

Erlikosaurus was a therizinosaur about 3.4 meters (11 feet) long, small for its family. It had a long neck, a small head with a toothless beak at the front, and small, leaf-shaped teeth behind, suited to cropping plants.

It is known from the most complete therizinosaur skull ever found, which has shown scientists much about how these odd dinosaurs fed.

Its world

It lived in the Late Cretaceous in what is now Mongolia. Its fossil comes from the Baynshire Formation, where it shared the land with the larger therizinosaur Segnosaurus, the raptor Achillobator and the armored Talarurus.

How it was found

Barsbold and Perle named Erlikosaurus in 1980, from a single find. The name comes from a god of death in Mongolian myth.
