Australopithecines have been found mainly in two African regions. These areas exhibit unique geological conditions that have allowed fossils to be preserved for millions of years. Drag the appropriate site type to the location in Africa where it is found.
South Africa: Limestone Caves
Eastern Africa: Sedimentary basins and river drainage systems

Explanation:

Australopithecines are from the genus hominicus, it existed in African between 1.9 - 4.2 million years ago. It is believed that the Homo-genus which includes modern human being descended from this genus.

Some 4.2 million years ago, it was discovered through archaeological findings that Australopithecus existed in the Eastern part of Africa and they spread through the continent before they became extinct 1.9 million years ago.

A specimen of genus Australopithecus was found in 1924 in South Africa at a Lime quarry by workers, also in 1959 the first Australopithecus was found in the Eastern part of Africa in Olduvai Gorge in Tanzania by Leakey.
