The minimal shaping and deep hard-hammer percussion scars on this artefact are typical for early Acheulean handaxes, but tools like these are also seen in earlier Oldowan assemblages. They are sometimes found in stone tool assemblages right through the Acheulean, co-occuring with the iconic finely-flaked handaxes that were made late in the period.
Handaxes are the earliest and longest-used ‘designed’ tool in human history, emerging in the archaeological record in Kenya (Kokiselei) and Ethiopia (Konso) ca. 1.75-1.8 million years ago. In North Africa, handaxes have been dated at Ain Boucherit in Algeria to 1.7 million years ago, and 1.3 million years ago at the Thomas Quarry site on the outskirts of Casablanca, Morocco. The earliest handaxes were likely made by Homo erectus, with the later handaxes in North Africa and Europe made by Homo heidelbergensis (also known as Homo rhodesiensis). Homo heidelbergensis is thought by many palaeoanthropologists to be the most recent common ancestor between modern humans like us and the Neanderthals. Fossils of Homo heidelbergensis have been found in the Sahara Desert region dating from ca. 600,000-700,000 BP, contemporary with North African Acheulean stone technology. The Acheulean period is thought to have ended about 170,000 BP, replaced by prepared core technologies, although handaxe manufacture persisted for longer in some regions.
