KNM-ER
3733
KNM-ER 3733, Homo erectus 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. The discovery of this
fossil in the same stratum as ER 406
(A. boisei) delivered the coup de grace to the single species hypothesis:
the idea that there has never been more than one hominid species
at any point in history. (Leakey and Walker, 1976) This is one of
the more complete cranium recovered from the Koobi Fora region.
This has been assigned to Homo Erectus. It shows marked differences
with Asian Homo Erectus specimens. It is similar in overall size
to those from Zhoukoudian in China however. The cranial capacity
has been recorded at 848 ml. Wear on the teeth suggest that this
was an adult individual. KNM-ER 3733 was found above the KBS tuff. |
