Australopithecus_aethiopicus

On the west side of lake Turkana in northern tanzania, Alan Walker made a most wonderful discovery of the Australopithecus aethiopicus. The Skull that was found had a sagittal Crest which meets the nachal crest to creat a crest simular to A. afarensis. The have the largest sagital crest in any known homid. They had a massive face, huge molars, flared cheek bones and a convace face with no forehead. They were thought to be alive approximately 2.7 million years ago in Southern Ethiopia, west of the Omo river. They were quiet established because they walked on two legs and they had thickly enameled molars and pre-molars to eat tougher food sources. They ate grainy foods that required a great deal of processing. Their nickname is black skull. Their brains were really small and had the brain capacity of 410cc.
