This protobiface belongs to the oldest Early Acheulean known so far in East Africa and in the world. It is made on a large flat cobble of phonolite (L= 235mm, W=132mm, T= 55mm). The two faces have been flaked successively to give a pointed shape to one extremity of the tool, but large natural surfaces (cortex) remain. Two different techniques have been applied to shape this large bifacial piece : percussion on passive hammer and hand held direct percussion.


The specimens displayed on this site are published specimens unless otherwise indicated. The information about the artifacts on this site is of a general nature only and unless otherwise indicated, has been written either by members of the African Fossils team, the National Museums of Kenya or the Turkana Basin Institute. The printed models are not of a high enough resolution to enable accurate scientific measurements and have generated using photogrammetry and in some cases low resolution digital models have been generated using laser scanners.
