In Western Australia’s northeast Kimberley region, on Balanggarra Country, a two-metre-long painting of a kangaroo spans the sloping ceiling of a rock shelter above the Drysdale River.
In a paper published today in Nature Human Behaviour, we date the artwork as being between 17,500 and 17,100 years old making it Australia’s oldest known in-situ rock painting.
We used a pioneering radiocarbon dating technique on 27 mud wasp nests underlying and overlying 16 different paintings from 8 rock shelters. We found paintings of this style were produced between 17,000 and 13,000 years ago.
