Red bull drawn in Indonesian cave dated to 40,000 years ago

WASHINGTON (AP) — Scientists have found the oldest known example of an animal drawing: a red silhouette of a bull-like beast on the wall of an Indonesian cave.

The sketch is at least 40,000 years old, slightly older than similar animal paintings found in famous caves in France and Spain. Until a few years ago, experts believed Europe was where our ancestors started drawing animals and other figures.

But the age of the drawing reported Wednesday in the journal Nature, along with previous discoveries in Southeast Asia, suggest that figurative drawing appeared in both continents about the same time.

The new findings fuel discussions about whether historical or evolutionary events prompted this nearsimultaneous “burst of human creativity,” said lead author Maxime Aubert, an archaeologist and geochemist at Griffith University in Australia.

The remote limestones caves on Borneo have been known to contain prehistoric drawings since the 1990s. To reach them, Aubert and his team used machetes to hack through thick jungle in a verdant corner of the island.

Strapping on miners’ helmets to illuminate the darkness, they walked and crawled through miles of caves decorated with hundreds of ancient designs, looking for artwork that could be dated. They needed to find specific mineral deposits on the drawings to determine their age with technology that measures decay of the element uranium.

“Most of the paintings we actually can’t sample,” said Aubert.

Aubert and his fellow researchers reported in 2014 on cave art from the neighboring Indonesian island of Sulawesi. They dated hand stencils, created by blowing red dye through a tube to capture the outline of a hand pressed against rock, to almost 40,000 years ago.

Now, with the Borneo cave art, the scientists are able to construct a rough timeline of how art developed in the area. In addition to the bull, which is about 5 feet (1.5 meters) wide, they dated red- and purple-colored hand stencils and cave paintings of human scenes.
