This dolomite band contains some of the best-known australopithecine sites in the world.
Known as the Oldowan industry, most of the earliest tools were rough cobble cores and simple flakes.
The flakes were used for such activities as cutting meat and skinning animals.
Although serving many purposes, these Acheulian tools were probably designed to butcher large animals, such as elephants, rhino and hippo, which had died of natural causes.
Because these animals were particularly dangerous, hominids were probably not yet able to hunt them.
Museum displays on human evolution are open to the public at Maropeng, on the edge of the World Heritage Site, and at Sterkfontein.
Stone age period Some hominids began to manufacture stone tools about 2.6 million years ago, thus beginning the Earlier Stone Age (ESA).Lee Berger and his team found the extraordinarily well-preserved remains of a juvenile male and adult female of a new species, .The hominids had fallen down a deep sink hole and were then covered by calcified sediment in an underground pool.Furthermore, tool kits included prepared cores, parallel-sided blades and triangular points.These points were hafted to make spears used to hunt large grazers such as wildebeest, hartebeest and eland.The sediment dates to between 1.78 and 1.95 million years ago. Although many specimens have been found in breccias, australopithecines did not normally live in caves.
