(a) Non-marine biodiversity within continental regions for a subsampling quorum level of 0.4, and palaeotemperature (δ18O) curve for the last ∼70 Myr ago17 (with weighted means (yellow circles)). (b) Global marine biodiversity for a subsampling quorum level of 0.4 (blue circles) and sea level curve18 (with weighted means (yellow circles)). Adamantina, Adamantina Formation subsampled crocodylomorph biodiversity; EECO, Early Eocene Climatic Optimum; MECO, Mid-Eocene Climatic Optimum; MMCO, Mid-Miocene Climatic Optimum; PETM, Paleocene-Eocene Thermal Maximum. Linear regression for pooled regional subsampling results on geological age in millions of years: log10 subsampled genera=0.0015 × age+0.244 (P=0.002; N=38; R2=0.221).
