WHAT IS THE CHELLEAN ?

CHELLEAN: An outdated classification term used for the first stage of biface manufacture believed to precede the Acheulian, and named after the type site of Chelles in the Somme Valley, France. It is now generally accepted that Chellean implements should be classified as early Acheulian. The term Chello-Acheulian, once applied to African Earlier Stone Age biface assemblages, has also been replaced by the term Acheulian.
