Extended Data Fig. 8: Estimation of regional diversity dynamics in the IAA across the Cenozoic with 5 Myr bin.
From: Cenozoic history of the tropical marine biodiversity hotspot
Bayesian inferences of (a) speciation rates per lineage, (b) extinction rates per lineage, (c) net diversification rates as the difference between speciation and extinction rates (rates below 0 indicate declining diversity), and (d) the changes in species richness. Solid lines indicate mean posterior rates, and the shaded areas show the 95% confidence interval. Early Oligocene, early Miocene, late Miocene, Pleistocene are shaded. Vertical dotted lines indicate epoch boundaries.
