Description:
Excavation in the previously little-explored western portion of Olduvai Gorge indicates that hominid land use of the eastern paleobasin extended at least episodically to the west. Finds included a dentally complete Homo maxilla (OH 65) with lower face, Oldowan stone artifacts, and butchery-marked bones dated to be between 1.84 and 1.79 million years old. The hominid shows strong affinities to the KNM ER 1470 cranium from Kenya (Homo rudolfensis), a morphotype previously unrecognized at Olduvai. ER 1470 and OH 65 can be accommodated in the H. habilis holotype, casting doubt on H. rudolfensis as a biologically valid taxon.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blumenschine, Robert J -- Peters, Charles R -- Masao, Fidelis T -- Clarke, Ronald J -- Deino, Alan L -- Hay, Richard L -- Swisher, Carl C -- Stanistreet, Ian G -- Ashley, Gail M -- McHenry, Lindsay J -- Sikes, Nancy E -- Van Der Merwe, Nikolaas J -- Tactikos, Joanne C -- Cushing, Amy E -- Deocampo, Daniel M -- Njau, Jackson K -- Ebert, James I -- New York, N.Y. -- Science. 2003 Feb 21;299(5610):1217-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Human Evolutionary Studies, Department of Anthropology, 131 George Street, Rutgers University, New Brunswick, NJ 08901-1414, USA. rjb@rci.rutgers.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12595689" target="_blank"〉PubMed〈/a〉
