Impressive drawings. But when it comes to petroglyphs I sometimes have my doubts if they are really old or fake. We saw some in Norway and Sweden and were wondering how they survived since ice age when everything else has vanished due to wind and weather…
you are right, petroglyphs are notoriously difficult to date, it’s all about circumstantial evidence, i.e. weathering patterns. that said that part of australia has not been affected by ice so that can be ruled out as a factor. still scientists are not sure about the precise age, sources say anything between 10.000 and more than 30.000 years, which in geological terms is a blink of an eye. 🙂
a way of better dating is – again circumstantially – through what is actually depicted. since it is known when megafauna animals or the thylacine died out we know that carvings depicting these animals must have been made before they disappeared.
