FIGURE 8.2.4. Crushed contents of a single fossil owl pellet containing the remains of a cotton rat (Sigmodon minor). Most of the cranium and possibly postcranial bones seem to have been crushed and appear as "bone hash" (area behind and beside the arrow) except for a partial rostrum with zygomasseteric plate (zmp), upper incisors (I1s), and upper molars (Ms), and associated left and right dentaries (Ld, Rd), humerus (h), and ulna (u). No other bones were found within a few cm of this group. Arrow points northward.
