Everything about Australopithecus Bahrelghazali totally explained
Australopithecus bahrelghazali is a
fossil hominin that was first discovered in
1993 1by the
paleontologist Michel Brunet in the
Bahr el Ghazal valley near
Koro Toro, in
Chad, that Brunet named
Abel. 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's proper name is KT-12/H1; "Abel" is the informal name, a dedication to Brunet's deceased colleague
Abel (hominid) Brillanceau. The specimen located roughly 2,500
kilometers West from the
East African Great Rift Valley and were only a few teeth and a partial jaw found in deposits thought to be 3.0 to 3.5 million years old.
The mandible KT-12/H1 discovered has similar features to the dentition of
Australopithecus afarensis; this has brought researchears like William Kimbel to argue that Abel isn't an exemplar of a separate
species, but "falls within the range of variation" of the
Australopithecus afarensis. By 1996, Brunet and his team classified KT 12/H1 as the holotype specimen for
Australopithecus bahrelghazali 2. This claim is difficult to substantiate,as the describers have kept KT 12/H1 locked away from the general paleoanthropological community, contrary to the
International Code of Zoological Nomenclature 1999
3. This species is a mystery to some as it's the only
australopithecine fossil found in
Central Africa. It is also of great importance as it was the first fossil to show that geographically there's a "a third window" of early hominid evolution.
