A small dromaeosaurid theropod from the Late Cretaceous of Argentina. Buitreraptor belongs to a group of southern-hemisphere dromaeosaurs called unenlagiines, which included Austroraptor, Unenlagia and potentially Rahonavis. The long, slender snout with dozens of small teeth, and elongate, slender hind limb bones suggest Buitreraptor was adept at chasing down small prey. The surprisingly short hands suggest the flightless wings of Buitreraptor may have had an unusual shape, although the purpose of that isn’t currently known.
