Buitreraptor gonzalezorum is the only known species of the genus Buitreraptor. The genus name means "Vulture-raptor", from the Spanish word buitre gist vulture.
Buitreraptor lived about 90 million years ago, when South America was a remote continent like Australia today. Buitreraptor has some different physical features than typical northern dromaeosaurs, like Velociraptor .From this scientists end that this dinosaur was not a big-game hunter like most other dromaeosaurs, but a seeker of small animals such as lizards and mammals. Its long bird-like arms confirm such a life of greedy fast-moving small prey. It has long legs and must have been an nimble runner. It most likely had feathers. This dromaeosaur occupied a niche like that of modern secretarybirds or even the dinosaur Troodon from North America.
