Abstract
Stone artefacts have been excavated from stratified contexts in the upper members of the Shungura Formation. One occupation site and several secondarily-derived concentrations of artefacts were found. Potassium-argon age determinations for these occurrences indicate an age of approximately 2.0 million years. The artefacts recovered offer a contrast to those known from Lower Pleistocene deposits at Olduvai Gorge, Tanzania, and from still older deposits east of Lake Rudolf in Kenya.
