Paraustralopithecus aethiopicus, also known as "Australopithecus aethiopicus", -2.5 millions years, southern Ethiopia. Institut royal des Sciences naturelles de Belgique (Brussels, Belgium). Made with ReMake and ReCap Pro from AutoDesk. Paraustralopithecus aethiopicus was discovered in southern Ethiopia by French archeologists Camille Arambourg and Yves Coppens in 1967. Paraustralopithecus aethiopicus has notable features that differ from the other robust australopithecines, including a larger zygomatic arch, extended ramus of the mandible, and a more prognathic face. These differences may have been developed during the evolution of aethiopicus, but it may also suggest that P. aethiopicus has a different phylogenetic history than A. robustus and A. boisei.
