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. 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.
