Paranthropus aethiopicus is an extinct species of hominid. The finding discovered in 1985 by Alan Walker in West Turkana, Kenya, KNM WT 17000 (known as the "Black Skull" due to the dark coloration of the bone, caused by high levels of manganese), is one of the earliest examples of robust pliocene hominids. The skull is dated to 2.5 million years ago, older than the later forms of robust australopithecines. Anthropologists suggest that P. aethiopicus lived between 2.7 and 2.5 million years ago. The features are quite primitive and share many traits with Australopithecus afarensis; thus P. aethiopicus is likely to be a direct descendant. With its face being as prognathic (projecting) as A. afarensis, its brain size was also quite small at 410 cc.
