Stone in South African cave boasts oldest-known human drawing

A small stone flake marked with intersecting lines of red ochre pigment some 73,000 years ago that was found in a cave on South Africa's southern coast represents what archaeologists on Wednesday called the oldest-known example of human drawing.

The abstract design, vaguely resembling a hashtag, was drawn by hunter-gatherers who periodically dwelled in Blombos Cave overlooking the Indian Ocean, roughly 190 miles (300 km) east of Cape Town, the researchers said.

It predates the previous oldest-known drawings by at least 30,000 years.
