Kow Swamp archaeological site
At first the skulls from Kow Swamp were thought to be from Homo erectus, not modern Homo sapiens. Thorne believed that it showed "the survival of Homo erectus features in Australia until as recently as 10,000 years ago". However, Donald Brothwell disagreed and said size and shape of the skulls at Kow Swamp had been caused by artificial cranial deformation.
