Acheulean industry PREHISTORIC TOOLMAKING WRITTEN BY: The Editors of Encyclopaedia Britannica See Article History Alternative Title: Acheulian industry Acheulean industry, Acheulean also spelled Acheulian, first standardized tradition of toolmaking of Homo erectus and early Homo sapiens. Named for the type site, Saint-Acheul, in Somme département, in northern France, Acheulean tools were made of stone with good fracture characteristics, including chalcedony, jasper, and flint; in regions lacking these, quartzite might be used. During the Acheulean period, which lasted from 1.5 million to 200,000 years ago, the presence of good tool stone was probably an important determining factor in the distribution of early humans. In the later stages they learned to bring stone from distant areas and thus became freer in their choice of homesites. “Tool kits” that differ in tool types reflect the varying adaptations made by early Stone Age humans to different environments.
