Australopithecus bahrelghazali (KT-12/H1) is a fossil hominin  discovered in 1995 by the paleontologist Michel Brunet in the Bahr el Ghazal valley near Koro Toro, in Chad. Named after the valley where it was discovered, Australopithecus bahrelghazali was dated by beryllium-based radiometric dating as living about 3.6 million years ago. The find consists of a mandibular fragment, a lower second incisor, both lower canines, and all four of its premolars, still affixed within the dental alveoli. The specimen locality is roughly 2,500 kilometers west of the East African Great Rift Valley, making it far removed from what broadly thought to be the "cradle" area of human evolution. (The specimen's proper name is KT-12/H1; Brunet named it Abel as a dedication to his deceased colleague Abel Brillanceau.)
