TABLE 1. Number of significant correlations between sea surface temperature, sea level, and marine crocodylomorph diversity (excluding metriorhynchoids), according to the corrections conducted on the datasets and time interval considered. All curves are reconstructed from means for each geological stage. Spearman rank correlation with Spearman’s rho values. Abbreviations: SST, sea surface temperature (Martin et al., 2014); SL-H, sea level (Haq et al., 1987); SL-M, sea level (Miller et al., 2005); Hett-Rup, Hettangian-Rupelian; Pli-Rup, Pliensbachian-Rupelian; To-Pria, Toarcian-Priabonian.
