Australopithecus
Artist's rendering of Australopithecus afarensis, which lived from 3.8 to 2.9 million years ago.
Australopithecus fossils have been discovered at numerous sites across eastern, north-central, and southern Africa. Because geological conditions favorable for the preservation and excavation of these fossils are uncommon, findings are largely restricted to specific regions:12
- Eastern Africa: Significant discoveries have been made in the Great Rift Valley, particularly in Ethiopia (such as the Hadar site) and Kenya (including sites around Lake Turkana like Koobi Fora, Kanapoi, and Allia Bay), as well as Tanzania (notably Laetoli).2345
- Southern Africa: Fossils have been recovered from limestone caves, with major sites including Sterkfontein, Makapansgat, and Taung.267
- North-Central Africa: Specimens have been found in the sedimentary deposits of the Chad Basin and the Djurab Desert in Chad.2
While these sites provide a window into the past, the actual geographic range of Australopithecus was likely much wider, though evidence is limited by environmental factors like acidic soils in tropical rainforests that hinder fossil preservation.2
