Figure 9. Comparison of biostratigraphic survey results for mammalian skeletal parts, teeth and axial post-cranial (vertebrae and ribs), based on the total number of records that could be identified to body part (NISP_SKM, Table 3).  A. Proportions of axial parts and teeth relative to total numbers of specimens identifiable to body part (NISP_SKM), plotted by stratigraphic level. Pink and blue arrows indicate proportions in a complete equid-bovid skeleton.  B. Ratio of teeth to axial parts; axial parts are more abundant than teeth in only a few levels (i.e., left of the dotted line; red arrow indicates ratio in a complete equid-bovid skeleton).  Teeth average 37% and axial parts 19% of the total sample of 1282 records.
