Oldest rock art discovered in Australia

Canberra, Australia: An archaeologist says tests show Aboriginal rock art in an Outback cave was made 28,000 years ago, making it the oldest in Australia and among the oldest in the world.[caption id="attachment_347674" align="alignleft" width="380" caption="AP"][/caption]The dating of one of the thousands of images in the rock shelter known as Nawarla Gabarnmang will be published in the next edition of the Journal of Archaeological Science.University of Southern Queensland archaeologist Bryce Barker said on Monday that the rock art was made with charcoal, so radiocarbon dating could be used to determine its age. Most rock art is made with mineral paint, so its age cannot be accurately measured.Australian National University archaeologist Sally May, who is not involved with Barker's research, described his find as "incredibly significant."AP
