Australopithecus bahrelghazali

Australopithecus bahrelghazali is an extinct australopithecine found in 1995 at Koro Toro in the Bahr el Gazel region of Chad, living around 3.5 million years ago in the Pliocene. It is the first and only australopithecine known from Central Africa, showing that the group ranged more widely than the East and southern Africa where it was first known. Many researchers doubt that it is a valid species and would assign the three partial jawbones and a premolar to Australopithecus afarensis. The site was a lakeside grassland with sparse trees, and isotope evidence points mainly to savanna foods such as grasses and sedges, though its teeth seem poorly suited to them.
