Appendix. Microwear data for 53 modern and 6 fossil squirrel teeth. For modern specimens, all counts were made in an area 0.30 x 0.30 mm on the metaconule of M2. Specimen numbers for modern specimens are from the University of Michigan Museum of Zoology, Mammal Division. On fossil specimens, counts were made over an area of the same size on the metaconule of M1 or M2 or on the metaloph for one M3. Specimen numbers for fossils are from the University of Michigan Museum of Paleontology (UMMP) or the Harvard-Geological Survey of Pakistan Project (YGSP). For large pits, gouges, and cross scratches, presence of the feature is indicated by a “1” and absence is indicated by a “0.” The scratch texture of each tooth is designated as 1=fine, 2=coarse, and 3=mixed fine and coarse.
