Table 1. A. Biostratigraphic survey data, with levels of approximately the same age combined; these data are used for secular trend analyses (Figure 6). Age and duration information from Barry et al. 2002. Turtle tallies were kept separately on the cards after the first year of surveying, and the total reptile counts combine numbered records and turtle tallies. NISPv is the sum of Fish, Mammal, and Total Reptile columns, representing the total number of specimens that could be identified at least to major vertebrate group. B. Raw data by survey level, showing the more detailed breakdown of the 24 levels, some of which are combined in A. C. Reptile data showing proportions of Chelonia, crocodyloids, and a few rare taxa.
