Big news this last week – mud wasp nests have been used to establish a date for certains types of Aboriginal rock art out in the Kimberleys. The Gwion Gwion art period has been set at around 12,000 years ago – roughly at the time of the Younger Dryas event. Some of it has a date of 16,000 years ago (which is the Oldest Dryas event) and the 12,000 year date is an average – via Bayesian methodology. See for example https://archaeologynewsnetwork.blogspot.com/2020/02/wasp-nests-used-to-d… …
… the rock art style is said to feature gracile humans with a wide range of decoration – head dresses, arm bands, necklets etc. See also https://phys.org/news/2020-02-wasp-date-ancient-kimberley-art.html … (https://doi.org/10.1126/sciadv.aay3922 ). The Kimberleys, in western Australia, contains some of the world's most visually spectacular and geographically extensive record of indigenous rock art – at tens of thousands of sites. It is important as it may help scientists better understand what was happening in the ancient environment.
… which provides an overview of the dates obtained.
