TABLE 2. — Correlation tests between the maximum sizes of Shungura Formation reptiles and sampling (overall reptile or order-specific) or member age. Each cell contains the Pearson correlation coefficient and the p-value for the test. For the sampling comparisons (data series with non-normal distributions), each cell also shows the Spearman rank correlation coefficient and corresponding p-value. Significant results after sequential Bonferroni correction are marked with **. 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.
