Also known by its field number, KNM-ER 1470, this is a cast of the only really good fossil of Homo rudolfensis, which lived about 1.8 million years ago. The original, found by Richard Leakey’s team near what is today Koobi Fora, Kenya, was originally thought to be a Homo habilis, but upon comparing its cranial metrics to other representatives of H. habilis, it has statistically demonstrable differences: a larger brain case, a longer face, and larger teeth. Consequently it was lumped into its own unique species of hominid. However, the debate is not settled. Questions of sexual dimorphism and even, perhaps, what genus it belongs to (some of the cranial features are almost more Australopithecine, but with a REALLY big brain…) still persist.
