Fossil remains, for Australopithecus bahrelghazali have been found in Chad, making it the only australopith currently known to have lived in North Africa.

Based on the identified partial mandible and maxilla, A. bahrelgahzali has relatively thin enamel, incisor-shaped canines, and three-rooted mandibular premolars. In many ways, A. bahrelghazali is similar to A. afarensis, but like Sahelanthropus tchadensis, the A. bahreghazali specimen has a more vertical lower face (i.e., reduced subnasal prognathism).

The type specimen for A. bahrelghazali is KT 12/H1, or "Abel", which was found at Bahr el Ghazal in Chad and dates between 3.4 and 3 million years ago.
