Field notes

About Buitreraptor

What it was like

Buitreraptor was a small feathered hunter about 1.3 meters (4 feet) long, from the southern branch of the raptor family. It had a very long, narrow snout filled with many small teeth without serrations.

Its slim jaws suggest it caught small animals, and some scientists think it may have hunted fish or lizards.

Its world

It lived about 113 to 110 million years ago, in the Cretaceous, in what is now Argentina. Its bones come from the Candeleros Formation, home also to the giant hunter Giganotosaurus and the long-necked Andesaurus and Limaysaurus.

How it was found

Makovicky and colleagues named Buitreraptor gonzalezorum in 2005. Its finds showed that raptors had spread to the southern continents and developed their own forms there.
