==History of discovery== thumb|left|Skeletal composite of specimens MPCA 245 and MPCA 238 Four specimens of Buitreraptor were found in 2004 in sandstone in Patagonia, Argentina during an excavation led by Sebastián Apesteguia, researcher of CONICET at the Fundacion Felix de Azara - Maimonides University, and Peter Makovicky, curator of dinosaurs at the Field Museum in Chicago. Buitreraptor is from the early Late Cretaceous Candeleros Formation, dating to the Cenomanian-Turonian ages approximately 98 to 97 million years ago, when South America was an isolated continent like Australia today. It was uncovered in a famous fossil site named La Buitrera, the "vulture roost". Although dinosaurs are rare in this site, another nearby site had earlier yielded the giant Giganotosaurus, one of the largest known carnivorous dinosaurs.
