Australovenator or “southern hunter” is a genus of theropod dinosaur from the Early Cretaceous Period (Albian Age) of Australia. It was recovered from the lower part of the Winton Formation and was first described in 2009 by Scott Hocknull and his colleagues. The type species, A. wintonensis, is named for the area it was found, about 37 miles northwest of the town of Winton. Only a partial skeleton was recovered including left dentary, teeth, partial forelimbs and hindlimbs, ribs, and a few other fragments.
The site where Australovenator was found has been interpreted as an oxbow lake deposit. The sauropod Diamantinasaurus was also found here, along with other specimens such as bivalves, fish, turtles, crocodilians, and plant fossils. Other dinosaurs were also found in the deposit.
Australovenator was a medium-sized dinosaur at 20 feet long. It was also about 6.6 feet tall at the hip. It has been described as a “cheetah” of its time, due to its light frame and predatory nature. Like other carnosaurs, Australovenator would have been a bipedal carnivore.
