Results from BC analysis of Lopingian-Early Jurassic terrestrial amniotes. Results from both non-phylogenetic (BC, red) and phylogenetic (pBC, blue) analyses of global biogeographic connectedness are shown. Shaded polygons represent 95% confidence intervals (calculated from jackknifing with 10,000 replicates) for both the BC and pBC analyses. The Permian–Triassic boundary (PTB) and Triassic–Jurassic boundary (TJB) extinction events are indicated by dotted lines. E. Tr.: Early Triassic
