The Bradshaw Paintings
I totally recommend this site to anyone interested in human evolution.
This art form was first recorded by Joseph Bradshaw in 1891, when he was lost on an Kimberley expedition in the north west of Australia. Dr. Andreas Lommel stated on his expedition to the Kimberleys in 1955 that the rock art he referred to as the Bradshaw Paintings may well predate the present Australian Aborigines. It has been dated to at least 17,000 years old, but so far no firm date for them has been set.
