The discovery of what is possibly the oldest rock artwork cataloged to date could point the way to even older art made by the ancient people who traveled through the Indonesian archipelago thousands of years ago.
"Petroglyphs made in limestone caves can sometimes be dated using uranium series analysis of calcium carbonate deposits (or 'cave popcorn') that naturally form on the cave wall surface used as 'canvas' for art will ", said Professor Aubert.
Professor Brumm said that as they dated progressively older cave art in and around the Indonesian archipelago, they would reinforce the evidence that rock art is a piece of cultural heritage that has been passed on for thousands of years when people made their first epic journey into the unknown.
