Geologic Age:
1.8 mya
Notes:
Mostly light beige skull cast of KNM-ER 3733. This skull cast represents a mature female skull of the early human species Homo erectus. The sex identification comes from a comparison of the anatomical features of her face with several other crania from Koobi Fora: KNM-ER 3883 (male), and KNM-WT 15000 (also male), found on the opposite side of Lake Turkana. The features of KNM-ER 3733 are markedly less robust. It's known to be an adult on the basis of the cranial sutures (which were fully closed), the extent of the wear on the teeth, and the eruption of the third molars before the individual's death. The real skull is about 1.8 million years old. The cast measures around 19.5 cm x 13.5 cm x 12 cm in size. Find out more by visiting humanorigins.si.edu
