Systematic Reworking of Lithics from Earlier Cultures in the Early Holocene of Dakhleh Oasis, Egypt.

A raw material form scarcely mentioned in the literature on lithic production—chipped stone artifacts manufactured by members of still earlier cultures—is used for a substantial portion of the toolkits in certain industries of Dakhleh Oasis, south-central Egypt. In one group of early Holocene (Masara) sites, the majority of double- patinated tools are chunky burins, systematically manufactured from Levallois flakes and similar thick-sectioned older artifacts. Since fresh chert and other workable stone is available in the area, it appears that old, recycled lithics constitute the preferred raw material for these tool classes. The sites in question seem to be field camps where the burins were both made and used. [ABSTRACT FROM AUTHOR]
