Homo habilis (KNM-ER 1470)

This cranium was put together from fragments found at Koobi Fora on the eastern side of Lake Turkana (1.9 my BP); see [Boyd & Silk 1997] , pp 373-377.

It is notable for its more "human" face and comparatively large endocranial cavity, suggesting a brain size of about 750 ml.

Most palaeo-anthropologists classify it as Homo habilis, but some suggest that it might be a species in its own right - Homo rudolfensis [Wood 1992] .
