Description
Considered large for a dromaeosaur, Austroraptor cabazai measured around 5 metres (16 ft) in length from head to tail. It is the largest dromaeosaur to be discovered in the Southern Hemisphere. Particularly notable about the taxon were its relatively short forearms, much shorter in proportion compared to those of other members of its family. The relative length of its arms has caused Austroraptor to be compared to another, more famous short-armed dinosaur, Tyrannosaurus.
The type specimen, labeled MML-195, consisted of a fragmentary skeleton including parts of the dinosaur's skull, a few neck and torso vertebrae, some ribs, a humerus, and assorted bones from both legs. The remains were found among deposits of the Allen Formation of Argentina, dating from the Campanian to the Maastrichtian stages of the Late Cretaceous period 70 million years ago. However little of the entire skeleton was found, what bones were available for analysis expressed some distinct characteristics that differentiate Austroraptor from other dromaeosaurs. A. cabazai's 80 centimeter-long skull was low and elongated, much more so than that of other dromaeosaurs.
