Approximate age:1,765,000 years old=average of minimum (1.72 Ma) and maximum (1.81 Ma)

Date based on: Linear extrapolation (visual projection) from nearby KBS and Kalochoro tuffs See map of sites with similar ages

Dating reference: 2011. An earlier origin for the Acheulian. Christopher J. Lepre, Hélène Roche, Dennis V. Kent, Sonia Harmand, Rhonda L. Quinn, Jean-Philippe Brugal, Pierre-Jean Texier, Arnaud Lenoble, Craig S. Feibel. Nature Volume: 477, Pages: 82?85 Date published: (01 September 2011) DOI: doi:10.1038/nature10372

Hominids: Oldowan  Acheulean    

Archaeology:      

Important specimens: Earliest Acheulean

Notes: Dating is not based on traditional physical connection (walking the outcropping facies). This will likely be a point of contention as there is no direct physical connection between the dated units and the artifacts. Units of younger age are known from nearby.

Location: Kokiselei KS4, Nachukui Formation, West Turkana, Kenya

Fossilized.org 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 fossilized.org has over 200 sites and hundreds of bibliographic citations.
