Statistical tests for significant differences/shifts in functional disparity and functional morphospace occupation between successive Mesozoic time bins. For comparative purposes, statistical tests for a disparity shift between the Carnian and Hettangian–Sinemurian are also provided. Disparity tests are based on paired-sample t-tests and likelihood ratios (LR). Functional morphospace occupation tests are based on nonparametric multivariate analysis of variance (NPMANOVA), performed on PC scores from the first 11 PC axes. Uncorrected and Bonferroni-corrected p-values are reported. Bold values represent statistically significant results where p-values are <0.05 and LRs are >8. See text in the “Stratigraphic Binning” section for full time-bin names and age ranges.
