The MOUSTERIAN tool tradition gets its name from artifacts discovered at a primitive rock shelter named Le Moustier located in southwestern France. Compared to the bulkier tools of the Acheulian produced by the Levallois technique, Mousterian tools are comprised of smaller flakes from an exhaustively worked core which are then retouched on the edges to make a large variety of tools. These tools are not only smaller than Acheulian specimens, but they are more specialized for their various tasks. Mousterian tools can be broadly put into four classes: 1) SAWS (Denticulate Tools) and KNIVES, 2) SCRAPERS 3) BORERS 4) HAND AXES, CHOPPERS and CLEAVERS.
Mousterian tool-makers were the primitive humans knows as the NEANDERTHALS. Neanderthals had massive skeletons and teeth, flat foreheads and heavy brow ridges. Their skulls were larger than a modern man and contained an average brain capacity of 1500 cc, averaging slightly larger than humans of today.
