Field notes

About Byronosaurus

What it was like

Byronosaurus was a small feathered troodontid, known from skulls. Its long, narrow snout had many small, needle-like teeth without serrations, unlike those of most of its relatives.

Tiny skulls of babies found with oviraptor eggs may belong to Byronosaurus.

Its world

It lived in the Late Cretaceous in what is now Mongolia. Its bones come from the Djadokhta Formation, where it shared the land with Velociraptor, Protoceratops, Oviraptor and Citipati.

How it was found

Norell and colleagues named Byronosaurus in 2000. Three finds are known.
