From: Animal residues found on tiny Lower Paleolithic tools reveal their use in butchery
Experimental residues after processing animal materials. (a) Patch of bone powder and collagen fibers from experimental periosteum removal. (b) Experimental yellow-reddish animal residue of fat, blood, and collagen fibers localized away from the edge of a tiny tool used in butchery. Notice the greasy, “mud-cracked” and desiccated appearance of the residue. (c) Elongated fibers left after butchery activity along the edge (d) Compressed animal residual matter on the cortical prehensile area after filleting meat. (e) Close-up on fat residual matter smeared far away from the edge of a small tool used for skinning hide.
