TABLE 3 in Body size histories of Shungura Formation reptiles in biotic and abiotic environmental context

TABLE 3. — Correlation between maximum size of reptile groups sampled in the Shungura Formation across the members of the formation. Each cell contains the Pearson correlation coefficient and the p-value for the test. A shows results for pairwise correlation tests between log 10 mass values and B shows results for pairwise correlation tests for the first differences in those values between members, not including results for Trionychidae because the sampled specimens come from too few consecutive members to calculate correlation in their first differences. NA indicates comparison with too few observations of change between bins in common between the two series to run correlation test. P-values under 0.05 which are not significant after Bonferroni correction are marked with *, and correlation coefficients over 0.75 are marked in bold. Crocodyluscf.
