Rodent Gnawing

LEPUS SP. (HARE OR JACKRABBIT)

DMNH 42147 from Mark's Sink (8/96); long bone fragment (figure 9.11). Measurements: GL, 45.05; GW, 13.40; LSW, 3.50. This long bone fragment has been severely altered through the process of postmortem gnawing, possibly by wood rats.

Splitting on the articular ends, the wedge-shaped bone loss areas, and the linear markings on the diaphysis are all consistent with this type of bone modification.
