This small tool is a Karari Industry scraper, was crafted from a small basalt pebble core and shows some signs of retouching that charactises the Karari Industy tools.
The Karari industry is a variant of the Olduwan Industry, which is characterized by these simple cores and flakes where sharp cutting edges are produced with little effort through simple percussion of a core against an anvil. The variability of the tools of this age between sites is dependent on the quality of the raw material. This tool was made from a lava pebble, and was recovered from the FxJj18 excavation in the Okote Member (1.65-1.39 Ma).
These Early Stone age tools classified as the Olduwan, named after Olduvai Gorge where Louis and Mary Leakey first discovered these artifacts.
