Using data from a Middle Paleolithic site at Bir Tarfawi in the Eastern Sahara, this study tests recent hypotheses that much of the typological variation apparent in the Middle Paleolithic can be traced to intensity of raw material use, and consequent reuse and reshaping of retouched tools. The Saharan material indicates that, although raw material was used quite intensively, the archaeologically defined types were desired forms in their own right and not simply stages in a reduction sequence.
