DOCUMENT Full-Text Kathryn Puseman.

The mid-section of a chert biface artifact from the La Purisima Mission Granary Site in Lompoc, California, was analyzed for possible protein residues. This artifact was discovered near the stone foundation of the La Purisima Granary and is believed to represent a hafted knife that was used either in agriculture or in skinning hides. Previous studies have shown that protein residues from a tool's surface can be identified using modified forensic procedures.
