The researchers found in Algeria, stone tools and animal bones with traces of cutting and dated them to the period of 1.9–2.4 million years ago. Found them in East Africa — in Kenya, Tanzania and Ethiopia. However, the new discovery allowed to talk about that ancient hominini (the Australopithecines) appeared in North Africa much earlier than expected by anthropologists. It is reported by Science.

Researchers have dated the artifacts and sediment, where they found several methods. Using paleomagnetic Dating, it is possible to measure the remanence of rocks — the intensity and the direction of magnetic field at a particular point in time.
Electron paramagnetic resonance allows the measurement of radioactive decay in quartz and carbonate rocks. As a result, they estimated the age of the top layer of 1.92, and the lower layer — 2.44 million years. In addition, the authors estimated the time of disappearance of animals, whose bones they had found in the Ayn Beherit, and look how it coincides with the received date.
Scientists from five countries under the leadership of Muhammad Sahnoun (Mohamed Sahnouni) from the National research center on human evolution continued excavations at ain El-Haneh and in 2006-2008 found in Boucherit ain (Ain Boucherit) two stratigraphic layers, which preserved the stone artifacts and animal bones with traces of cutting.
Guns, among which were single – and double-axes and flakes were made of Sandstone and flint. Among the remains, the researchers found the bones of Kolpochoerus heseloni, ancient pigs, presumably extinct about 1.7 million years ago; the extinct horse Equus numidicus and representative of the family elephant Anancus, which went extinct about 2.5 million years ago.
