Field notes

About Saurornithoides

What it was like

Saurornithoides was a slender, feathered theropod from the troodontid family. It had large eyes, a long narrow snout full of small teeth, and long legs for running. Like its relatives, it probably hunted small animals and may have eaten some plants too.

Its world

It lived in the Late Cretaceous in what is now Mongolia. Its first bones come from the Djadokhta Formation, a dry land of dunes where Protoceratops, Velociraptor and the armored Pinacosaurus also lived.

How it was found

Osborn named Saurornithoides in 1924. The name refers to its bird-like skull. A second species once placed here is now often treated as a separate genus.
