Approximate age:1,075,000 years old=average of minimum (0.7 Ma) and maximum (1.45 Ma)

Date based on: Potassium-Argon See map of sites with similar ages

Dating reference: de la Torre (2011). The Early Stone Age lithic assemblages of Gadeb (Ethiopia) and the Developed Oldowan/early Acheulean in East Africa. Journal of human evolution.

Hominids:       

Archaeology:Acheulean  Developed Oldowan  Possible fire  

Important specimens: Very large collection of lithics with abundant handaxes. Claims of fire (Bellmo 1993 & James 1989) based on burned rocks, Hippo butchery

Notes: Large collection flooded in 1980?s

Location: southeast rift margin, Upper Webi Shebele Basin , Ethiopia
Map location/coordinates reference: The Webi Shebele Gorge was dammed in the 1980?s, flodding some of Desmond Clark?s 1970?s excavations at Gadeb, but de la Torre (2011) reports that some sediments remain exposed. See de la Torre (2011). The Early Stone Age lithic assemblages of Gadeb (Ethiopia) and the Developed Oldowan/early Acheulean in East Africa. Journal of human evolution.
