Approximate age:300,000 years old=average of minimum (0.1 Ma) and maximum (0.5 Ma)

Date based on: Guesswork, but certainly above lower Chari Member, which tops out at 730k. "The stratigraphic revision at Koobi Fora covers only the Omo Group deposits there, but some later deposits do occur in the region. Two hominids, KNM-ER 999 and KNMER 3884, were formerly attributed to the Guomde Formation, most of which has been subsumed into the Chari Member of the Koobi Fora Formation (Brown and Feibel, 1986). These two fossils, however, derive from undifferentiated later deposits, probably in the time span 0.5 to 0.1 my."

Key references: 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.
