I struggle to keep my footing on a narrow ridge of earth snaking between flooded fields of rice. The stalks, almost ready to harvest, ripple in the breeze, giving the valley the appearance of a shimmering green sea. In the distance, steep limestone hills rise from the ground, perhaps feet tall, the remains of an ancient coral reef. Rivers have eroded the landscape over millions of years, leaving behind a flat plain interrupted by these bizarre towers, called karsts, which are full of holes, channels and interconnecting caves carved by water seeping through the rock.

A nearly-life-size depiction of a kangaroo — realistic genitalia included — is the oldest known rock painting in Australia. Scientists recently pinpointed its age to 17, years ago with a technique that had never been used on Australian ancient art before: measuring radioactive carbon in wasp nests from rocks near the artwork. The kangaroo painting extends across the ceiling of a rock shelter and spans nearly 7 feet 2 meters , which is roughly the height of a modern kangaroo. This and other paintings in northwestern Australia's Kimberley region share certain stylistic features with the earliest cave art from Europe and Asia, the researchers reported.
