About

Australian scientists have discovered the country's oldest known rock art - a 17,year-old painting of a kangaroo. The artwork measuring 2m 6.

Description

A collaboration led by the University of Melbourne in cooperation with Traditional Owners in the Kimberley has used fossilised mud wasp nests to find dates for the oldest Aboriginal rock art. Traditional owner, Ian Waina, contemplating a painting of a kangaroo that we now know must be more than 12, years old based on radiocarbon dating of wasp nests overlying it.

Continuing work using fossilised mud wasp nest to find minimum and maximum ages for Australian Aboriginal rock art, a collaboration led by Dr Damien Finch and Prof Andy Gleadow of the University of Melbourneincluding Centre radiocarbon expert Dr Vladimir Levchenko, has published these latest in Nature Human Behaviour. The work was undertaken with the permission and participation of the Balanggarra Aboriginal Corporation, Rangers and Traditional Owners in the Kimberley.

It commonly depicts naturalistic animals but includes handprints and stencils, stencils of objects, depictions of plants, often yams, and a few anthropomorphs. Pigment from these older paintings contains no carbon materials that can be dated directly. It is only by dating mud wasp nests or surface mineral accretions, found directly over or under the pigment, that scientists can determine minimum or maximum age constraints for the paintings themselves. The Pleistocene age is the oldest reported so far for a rock art painting in Australia.

For one painting of a 2-metre long kangaroo, we dated three nests overlying it and three more underlying it so we know the painting must be between 17, and 17, years old. Finch established the validity of the approach in publications during his recently concluded studies as a PhD candidate at the University of Melbourne.

And our samples are mostly sand, with some minute charcoal fragments. More than 75 fossilised mud wasp nests, which contained enough carbon in the form of microscopic charcoal particles to be measured by radiocarbon dating, were measured by Centre scientist, Dr Vladimir Levchenko.

The team ly dated rock art from the more later Gwion Gwion period also in the Kimberley in a paper published in Science Advances. Finch et al reported that the combined data from the 27 radiocarbon dates suggests that paintings in this Naturalistic style were produced over a time span from, at least 17, to 13, years ago. on The Conversation and the University of Melbourne website.

Radiocarbon dating is a well-known method for determining the age of materials up to the age of approximately 50, years. Over the last decades, neutron, photon, and ion beams have been established as an innovative and attractive investigative approach to characterise cultural-heritage materials.
