Buitreraptor gonzalezorum is an extinct genus of dromaeosaurid theropod dinosaur that lived in Argentina during the Late Cretaceous period. Discovered in 2004 but not described until 2005, this early late cretaceous dromaeosaurid weighed just 3 kilograms and was 1.5 metres long according to estimates by Gregory S. Paul in 2010. This small dinosaur was different to many typical dromaeosaurids due to its slender elongated snout full of of many small serated teeth. It has been concluded that this dinosaur hunted small lizards and mammals rather than larger prey like some other dromaeosaurs. No feathers have been found but it is highly likely that it did have them as some of its close relatives like Sinornithosaurus and Microraptor have been found with feathers.
