University of Southern Queensland archeologist Bryce Barker said Monday that found the rock in June last year but only recently had it dated at New Zealand’s University of Waikato radiocarbon laboratory.
He said 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.
“It’s the oldest unequivocally dated rock art in Australia” and among the oldest in the world, Barker said.
