TABLE 5. — Correlation statistics of reptile and mammal maximum sizes with a) environmental variables across members of the Shungura Formation. 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, Cercopithecidae, or soil temperature because those series have too few consecutive members sampled to calculate correlation in their first differences. Each cell contains the Pearson correlation coefficient and p-value for the correlation test. The row marked S has non-normally-distributed data, so the correlation test results shown are the Spearman rank correlation coefficient and corresponding p-value. The cercopithecids, Hippopotamus sp., and soil temperature data series are excluded from B because they include too few consecutive members sampled. NA indicates other comparisons 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 *, p-values which are significant after Bonferroni correction are marked with **, and correlation coefficients over 0.75 are marked in bold. Data from Heinzelin (1983), Passey et al. (2010), Levin (2015) and Nutz et al. (2020).
