Used Bone Fragments
There are ten other fragments of bone which show use. The largest of these measures 4¼ × ¾ inches, the smallest, 3¼ × ⅝ inches. One or more edges are worn, suggesting use as a scraper or cutting edge. Bones of large animals, probably long bones, appear to be represented. On most, the working edge is concave, although on a few it is flat.
Notched Bone
One bone is similar to those described above but has a series of notches along one edge. It is 4 inches long and ⅝ inches wide.
Rib-scapula Cutting Tools ([Fig. 50])
There are nine rib and one scapula fragment that show wear along a sharp edge. These appear to have been used as cutting implements. Some are polished along the flat face, perhaps from use in some kind of smoothing. Many Southwestern tribes, e.g. the Papago, use similar tools to remove hair from fresh hides. It is difficult to know whether these represent complete tools or fragments. The largest is 7 inches long, the smallest 2½ inches long. The identifiable specimens are of bison or mule deer (Odocoileus hemionus).
Gaming Pieces ([Figs. 51], [52])
Seven specimens of worked bone are thought to have been used as gaming pieces. For three of these, this designation is relatively certain. These are small flat oblong objects with a series of parallel striations on the edges of one face. In addition, two have a line of indentations running up the center. These depressions were probably drilled ([see Fig. 52]).
