Summary of values for Pearson's product–moment coefficient for comparisons of key data series used in this study. Values above the diagonal represent correlations for raw data series; values below the diagonal represent correlations for generalized difference data series. Values in bold are statistically significant after correction for multiple comparisons; values marked with an asterisk were significant only prior to application of corrections for multiple statistical tests (α = 0.05). p-values are not reported here for correlations between most raw data series because these are heavily biased by temporal autocorrelation (see text). Statistical results using first differenced and detrended data series, and using Spearman's rank and Kendall's τ coefficients, are presented in the electronic supplementary material. DBCs, dinosaur-bearing collections; DBFs, dinosaur-bearing formations; TDE, taxic diversity estimate.
