Female Homo ergaster skull

This is a cast of KNM-ER 3733. The original skull was discovered in 1975 by Bernard Ngeneo and Richard Leakey in Koobi Fora, East Turkana, Kenya. It is dated to between 1.5 and 1.9 million years old.

This is the skull of an adult female. Females had less robust features compared with males such as ‘Turkana Boy’. It is considered an adult because the cranial sutures were fully closed, it had considerable wear on the teeth, and the third molars had erupted.
