Austroraptor was a fairly large species of raptor from the Bajo de Santa Rosa locality of the Allen Formation, in Río Negro, Argentina. It lived in the Maastrichtian age of the Late Cretaceous, about 70 million years ago. It actually is on the upper end of dromaeosaurid size, growing up to 5 meters long and 1.5 meters tall. Only Achillobator and Utahraptor approach its length. It is also the largest dromaeosaur found in the Southern Hemisphere. Its known from a partial skull fragment and partial skeletal remains. It had relatively short front limbs, similar to Tianyuraptor and Mahakala. It had conical, non-serrated teeth like spinosaurids. It had a long, narrowing skull, rather than a box like one like most dromaeosaurids. It lived alongside many early mammals, pterosaurs and the titanosaurids Saltasaurus and Rocasaurus, which it may have eaten.
