Homo ergaster skull KNM-ER 3733 (1.75 million years)

The Homo ergaster skull KNM-ER 3733 with dentition was discovered by B. Ngeneo in 1975 in Koobi Fora, Kenya, and described by R. Leakey in Nature in 1976.  Several teeth are intact, but no mandible was ever found.  Of great significance is the fact that this skull was found in the same sediment layer that A. boisei KNM-ER 406 had been six years earlier, adding to the evidence against the single species hypothesis, the notion that only one hominid species existed at any time in history.  Also known as Homo erectus, KNM-ER 3733 is said to be very similar in appearance to the H. erectus finds of Peking, China, including a cranial capacity of 850cm³, keeling of the cranium and the presence of an occipital torus.  Due to its features (including wear on teeth and closure of cranial sutures) and compared to KNW-WT 15000, this specimen is considered to be a mature female.

The Bone Clones® Hominid Series

Our aim is to provide the best possible facsimile models of the most important hominid finds for the general public, educators and students, using the best reference material available.  Each hominid has been carefully researched and re-created based on some or all of the following: casts of original fossils, the latest literature (descriptions and/or published measurements), input from the scientific community and full colour, life-size photographs.  Every effort has been made to accurately re-create anatomical details of colour, size, shape, reconstructed areas, and bone/fossil texture.  The hominids offered in this series are high quality, artistic recreations that can be advantageously used by educators as important visual aids in the classroom and appreciated by the general public.  They are not intended for advanced graduate work nor to be measured for research purposes.
