Here’s what you’ll learn when you read this story:Discovered in an Indonesian cave, hand stencils with fingertips that taper to points are now though to be the oldest rock art in the world. The stencils and other rock art in this region suggest that it was first populated during the last Ice Age by people who crossed the sea on their way to Australia. What Aubert and his team found in that cave is some of the oldest rock art in the region—and, possibly, the world. Other prints like this found in the area were over 16,000 years more recent than theses Muna cave prints, which are a thousand years older than even the oldest known cave art made by Neanderthals (in what is now Spain). To find out the approximate age of the hand stencils and surrounding cave art, the archaeological team relied on calcite deposits.
