From: Animal residues found on tiny Lower Paleolithic tools reveal their use in butchery
Example of animal residues found on small recycled flakes. (a) Double ventral lateral item AQ15a 71-12-08 #79. (b) Hinge and snap scars running along the outer edge with a close regular distribution and associated to a mixed motion on soft to medium material. (c) SEM image of collagen fibers smeared and entrapped in a wide scar along the used edge (BSE-SEM image). (d) SEM-EDX spectrum of the collagen fibers showing the characteristic peak of sulphur. (e) Double ventral regular item AS14d 71.14-13 #8. (f,h) SEM image of amorphous patches of white bone residues along the used edge (BSE-SEM image). (g) OLM image of white-yellow greasy amorphous structures compressed across a zone of prehension. In the close-up, note birefringent yellow collagen fibers entrapped inside the smeared residue.
