Hominids: Australopithecus boisei       

Archaeology:Oldowan/undiagnostic  Disputed evidence for fire    

Important specimens: KNM-CH 1, a right hemiface and anterior cranial base, KNM-CH 304 a frangmentary cranium.

Notes: Evidence for use of fire here is inconclusive. The original authors clearly state that it is possible this fire was made by lightning strikes or brush fires. See Gowlett, J. A. J., Harris, J. W. K., Walton, D., & Wood, B. A. (1981). Early archaeological sites, hominid remains and traces of fire from Chesowanja, Kenya. ; Keywords: paranthropus Paranthropus

Location: Chemoigut Formation, Lake Baringo Area, Kenya

Key references:   Wood, B. (Ed.). (2011). Wiley-Blackwell Encyclopedia of Human Evolution, 2 Volume Set: Wiley-Blackwell. presents precise geographic locations and current best date estimates for late Miocene, Pliocene, and Pleistocene sites with human ancestor (hominin) fossils and archaeology. Several interactive visual interfaces allow users to generate maps and tables that relate localities, fossils, tools, and evolutioanry events with geography and time. The data content is dynamic and is updated daily, as are new interface features. This site started as a course syllabus for Anthropology 3101: Human Evolution 2 at California State University, East Bay, and grew with each quarter it was used. Now has over 200 sites and hundreds of bibliographic citations.
