Buitreraptor is a small dromaeosaur from the Cretaceous of Argentina. It was about four to five feet long (1.5 metres).[1]

Buitreraptor has a slender, flat, extremely elongated snout. Its jaws have many small teeth which lack meat-tearing serrations or cutting edges. They are grooved, strongly recurved and flattened.[2] This probably meant it ate quite small animals, like lizards and mammals.

Since its close relatives had feathers, it is likely that Buitreraptor also was feathered.
