Anotations

Scope note:

Refers to the period of European and African prehistoric stone tool development dating to the Pleistocene Epoch and distinguished from the Abbevillian tradition in its evolution from crude choppers to finer flint hand axes, cleavers, borers, scrapers, knives with heavily serrated blades having a saw-like appearance, and implements of bone, horn, and wood that was hardened by exposure to fire.
