I think you probably men Homo-Erectus. The Aboriginies are nothing like Cro-Magnon. Some of the Aboriginies alive today have brow-ridges that are even more severe than was Neanderthal Man.
Thanks for replying Blam, I didn't realize that this was a three year old thread when I first posted. It may well have been Homo-Erectus although I personally think Aborigines are a more modern type than that. Their morphology is fascinating though.
