The existence of an Australian allosaurid is based on an ankle bone discovered in the sea cliffs of Cape Paterson in south-eastern Australia, near the famous Dinosaur Cove site. This bone was referred to the genus Allosaurus; if it really is a species of Allosaurus then it’s not only a small species (estimated to have been around 6 metres in length), but it’s also a very late surviving species, as it came from Early Cretaceous rocks, whereas other Allosaurus species were from the Jurassic.
