Skull KNM-ER 3733

ER 3733

KNM-ER 3733, Homo erectus (or Homo ergaster)

Discovered by Bernard Ngeneo in 1975 at Koobi Fora in Kenya. Estimated age is 1.7 million years. This superb find consisted of an almost complete cranium. The brain size is about 850 cc, and the whole skull is similar to some of the Peking Man fossils. Because the facial features are less robust than that of the Turkana Boy, this skull is thought to be female.

The brain size of 850 cc is extremely small by modern standards. A very similar skull, ER 3883, is even smaller, at 800 cc.
