Austroraptor

Austroraptor ( ) is a genus of paraviandinosaur in the clade Unenlagiinae known from the Late Cretaceous (Campanian–Maastrichtian ages) Allen Formation of Argentina.

Austroraptor was a large, moderately-built, ground-dwelling, bipedal carnivore, measuring around 5–6 m (16–20 ft) long and weighing up to 300–520 kilograms (660–1,150 lb). It is one of the largest paravians known, with only large dromaeosaurids such as Achillobator and Utahraptor approaching a similar size.
