Title |
Lower Palaeolithic hand axe |
||
Description |
English: A complete lower Palaeolithic, Acheulean, bifaced ovate flint hand axe. The axe is oval in plan, pointed oval in cross-section and has a flat striking platform at the base. Both sides display flake scars that generally run from the edge inwards. One side has three broad and long flake scars that run from the striking platform to just below the apex. The majority of these flake scars display a rust-orange colour patina. The flint is mottled cream colour.
The striking platform is roughly lozenge shaped and measures 38mm x 17mm. Such hand axes were in widespread use from c.600,000 to 245,000 years ago in Britain although most finds date from 500-300,000 years ago corresponding to a period of warmer climate. They were produced by the hominid species Homo heidelbergensis. It has been suggested ovate hand axes were used more for cutting like a knife rather than as an axe. |
