An archaeologist says he has found the oldest piece of rock art in Australia and one of the oldest in the world: an Aboriginal work created 28,000 years ago in an outback cave.
The dating of one of the thousands of images in the Northern Territory rock shelter, known as Nawarla Gabarnmang, will be published in the next edition of the Journal of Archaeological Science.
The archaeologist Bryce Barker, from the University of Southern Queensland, said he found the rock in June last year but had only recently had it dated at the radiocarbon laboratory of New Zealand's University of Waikato.
