Mousterian stone technology is generally described as a "flake technology. This means simply that the final, carefully worked tools are chipped out of rather amorphous rough outs, or blanks, about as long as they are wide. These are removed from large globular chunks of stone known as "flake cores." Also surprising is the similarity of Mousterian stone tools from region to region. In form and relative number, they are often virtually identical across vast distances; collections from sites in France often cannot be distinguished from those found in the Near East, for example. Some typical Mousterian stone tools include convex scrapers, Levallois points and handaxes.
