Australopithecus bahrelghazali, une nouvelle espèce d'Hominidé ancien de la région de Koro Toro (Tchad)

A mandible and first upper premolar discovered in North Chad by the Franco-Chadian Paleoanthropological Project demonstrate for the first time the presence of an australopithecine west of the Rift Valley. The Chad hominid presents a combination of primitive and derived characters which distinguishes it from all other early hominid taxa and which suggests that this new species represents a clade independent since 4 Ma or more.
