Field notes

About Shuvuuia

What it was like

Shuvuuia was a small alvarezsaur, a bird-like theropod about 0.6 meters (2 feet) long. It had long legs, a light skull, tiny teeth and very short, strong arms with one large claw. That claw may have been used to break into insect nests.

Its world

It lived in the Late Cretaceous, in what is now Mongolia. It comes from the Djadokhta Formation, a sandy land shared with Velociraptor, Protoceratops, the oviraptorid Citipati and the armored Pinacosaurus.

Its eyes and ears suggest it could see in dim light and hear very well, so it may have hunted at night.

How it was found

Chiappe and colleagues named Shuvuuia in 1998. The name comes from the Mongolian word for bird. Well preserved skulls have made it one of the best known alvarezsaurs.
