Australovenator (meaning "southern hunter") is a genus of allosauroid theropod dinosaur from Albian (Early Cretaceous)-age rocks (dated to 95 million years ago) of Australia. It is known from partial cranial and postcranial remains which were described in 2009 by Scott Hocknull and colleagues.
Description and history 
Australovenator is based on AODL 604 (affectionately named "Banjo" after Banjo Paterson) a partial skeleton including a left dentary, teeth, partial forelimbs and hindlimbs, a partial right ilium, ribs, and gastralia. Australovenator was described in 2009 by paleontologist Scott Hocknull of the Queensland Museum, and colleagues. The type species is A. wintonensis, in reference to nearby Winton. A phylogenetic analysis found Australovenator to be an allosauroid carnosaurian, with similarities to Fukuiraptor and carcharodontosaurids. In the initial analysis, it was shown to be the sister taxon of the Carcharodontosauridae. More detailed studies found that it formed a clade with several other carcharodontosaurid-like allosaurs, the Neovenatoridae.
The ankles of Australovenator and Fukuiraptor are similar to the Australian talus bone known as NMVP 150070 that had previously been identified as belonging to Allosaurus sp., and it is likely that this bone represents Australovenator or a close relative of it. Alternatively, this bone could belong to an abelisaur.
More arm elements of the holotype were described in 2012.
AODL 604 was found about 60 kilometres (37 mi) northwest of Winton, near Elderslie Station. It was recovered from the lower part of the Winton Formation, dated to the latest Albian. AODL 604 was found in a clay layer between sandstone layers, interpreted as an oxbow lake, or billabong, deposit. Also found at the site were the type specimen of the sauropod Diamantinasaurus, bivalves, fish, turtles, crocodilians, and plant fossils. The Winton Formation had a faunal assemblage including bivalves, gastropods, insects, the lungfish Metaceratodus, turtles, the crocodilian Isisfordia, pterosaurs, and several types of dinosaurs, such as the sauropods Diamantinasaurus and Wintonotitan, and unnamed ankylosaurians and hypsilophodonts. Plants known from the formation include ferns, ginkgoes, gymnosperms, and angiosperms.
Australovenator was a medium-sized allosauroid. According to Hocknull, it was 2 metres (6.6 ft) tall at the hip and 6 metres (20 ft) long, with a weight of about 500-1000 kg. Because it was a lightweight predator, he coined it as the "cheetah of its time". Like other carnosaurians, Australovenator would have been a bipedal carnivore.
