EP Gallery: Middle Acheulian -- Olorgesailie, Olduvai Gorge, Near East, Abbevillian (c. 1.0 MYA to 500,000 BP) / k)oldvheb3pl8
Comment: As at Olorgesailie, the handaxe and cleaver are predominate bifaces at Olduvai Gorge Middle Acheulian sites. Bed IV sites are dated 600-800,000 BP.
Bed IV HEB Level 3: "cleaver and five handaxes made from fine-grained green phonolite. The rough surface of some specimens, such as that in the centre at the top, is due to weathering."
