Bite Marks and Shell Disease Comparison: Tables

TABLE 1. Previous field numbers, current specimen identification numbers, element and taxonomic identification of each element. * = taxonomic revisions based on Adrian et al., 2019.

TABLE 2. µCT scanning parameters for specimens included in this study.

TABLE 3. Measurements of unmodified and modified shell regions. Cortical bone thickness = average of unmodified region of bone immediately to the left and right of the modified region, taken from µCT slices representing the region of maximum mark penetration into the cortical bone. Pathology thickness = thickness of the observed cortical bone at the point of maximum mark penetration. Note, measurements of 0 are recorded when trabecular bone is exposed in the bottom of the mark, measurements of 0* represent specimens in which the affected bone has fractured, leaving a gap in the bottom of the mark. Maximum depth = measured relative to the projected curvature of the surface of the shell, as suggested by the unmodified bone to the immediate to the left and right of the modified region, taken from CT slices representing the region of maximum mark penetration into the cortical bone. Maximum width = the widest diameter of the modified shell region.
