World's oldest cave art discovered in Indonesia

A red stencil of a hand pressed against the wall of an Indonesian cave is the oldest rock art ever discovered, scientists said on Wednesday, and sheds light on how humans first migrated to Australia.

The cave art dates back at least 67,800 years, according to research published in the journal Nature by a team of Indonesian and Australian archaeologists.

"We have been working in Indonesia for a long time," study coauthor Maxime Aubert of Australia’s Griffith University told AFP.

This time they ventured to caves on the island of Muna in the Sulawesi province on the advice of Indonesian archaeologist Adhi Agus Oktaviana, the study’s lead author. There they found "handprints in negative, stencilled, probably using red ochre," Aubert said.
