Abbevillian

Abbevillian is a currently obsolescent name for a tool tradition that is increasingly coming to be called Oldowan (or Olduwan). The original artifacts were collected from road construction sites on the Somme river near Abbeville by a French customs officer, Boucher de Perthes. He published his findings in 1836.

Subsequently Louis Laurent Gabriel de Mortillet (1821–1898), professor of prehistoric anthropology at the School of Anthropology in Paris, published (1882) "Le Prehistorique, antiquité de l'homme", in which he was the first to characterize periods by the name of a site. Many of his names are still in use. His first two were Chellean and Acheulean.

Chellean included artifacts discovered at the town of Chelles, a suburb of Paris. They are similar to those found at Abbeville. Later anthropologists substituted Abbevillian for Chellean, the latter which is no longer in use.

The label Abbevillian prevailed until the Leakey family discovered older (yet similar) artifacts at Olduvai Gorge (a.k.a. Oldupai Gorge), starting in 1959, and promoted the African origin of man. Olduwan (or Oldowan) soon replaced Abbevillian in describing African and Asian paleoliths. The term Abbevillian is still used, but it is now restricted to Europe. The label, however, continues to lose popularity as a scientific designation.

Mortillet had portrayed his traditions as chronologically sequential. In the Abbevillian, early Palaeolithic hominins used cores; in the Acheulian, flakes. Olduwan tools, however, indicate that in the earliest Palaeolithic, the distinction between flake and core is less clear. Consequently, there also is a tendency to view Abbevillian as an early phase of Acheulian.

The Abbevillian type site is on the 150-foot terrace of the River Somme. Tools found there are rough chipped bifacial handaxes made during the Elsterian Stage of the Ice Age, which covered central Europe between 478,000 and 424,000 years ago.
