Fig. 2: Global ammonoid diversification dynamics in the Late Cretaceous.
From: Late Cretaceous ammonoids show that drivers of diversification are regionally heterogeneous
Diversification dynamics (mean + highest posterior density estimates—HPDs) were estimated at genus and species levels from spatially standardised data in a Bayesian framework that accounts for temporal sampling biases. Ocean Anoxic Event 2 is marked in each panel by the dashed yellow line. A Global mean extinction rate and 95% HPD estimate. B Global mean origination rate and 95% HPD estimate. C Global mean diversification rate and 95% HPD estimate. D Global mean genus and species richness and 95% HPD estimates. E Regional mean genus richness with 75% and 95% confidence intervals. F Regional mean species richness with 75% and 95% confidence intervals. Source data is available in the electronic supplement accompanying this paper.
