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_).
