Australovenator (Southern hunter) is a recently-named neovenatorid, a family of the
allosaurs, from Australia. It reached about 5-7 metres in length, a 1-2 tonnes in weight. Australovenator, means, 'Southern Hunter'. Originally this Dinosaur was dubbed, 'the Polar Allosaur', because immediately it seemed to be from the Allosauridae. Even so, a Palaeontologist specialised in studying ankle bones, one of the few rare pieces of skeletal evidence we do have for this Dinosaur, highlighted the bones are suitably different from true Allosaurs as so to group them in a very closely related, but still different family - the Neovenatorids. At the same time Neovenator lived in Britain, and Afrovenator lived in Africa, this was the Australian answer, for this advanced Cretaceous line, that actually began to themselves decline as had the true Allosaurs and Megalosaurs, in the face of competition from newer predators, such as the Tyrannosaurids.
