Figure 7. Relationship of identifiable bones to unidentifiable scrap, i.e., fossil fragments that are not certainly identifiable either to major vertebrate group or body segment.  Total NISPV (identifiable bones) = 1877; Total N(scrap) = 3004 from 33 biostratigraphic surveys (all blocks and individual collectors combined for each numbered survey). Survey KL11 is an outlier that has an unusual number of identifiable bones relative to scrap, which may relate to relatively fresh eroding outcrop surfaces (see photograph in Figure 4).
