Table 2. Bone Surface Modifications.
Types of bone surface modifications found in the Mygatt-Moore assemblage. Numerous elements preserved multiple types of traces; therefore, this is a tabulation of all individual traces, not individual bone elements. Subtotals for larger bone surfaces modification categories (i.e., bite marks, invertebrate traces, and other) are denoted in grey cells and bold text.
