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 (NISPSKM, Table 3).  A. Proportions of axial parts and teeth relative to total numbers of specimens identifiable to body part (NISPSKM), 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.
