Fig. 2. Fossil lineages through time in six extant reef coral families.

a Reconstruction of fossil diversity trajectories estimated through a time-variable Poisson process of preservation. Models were run independently in each family and were replicated fifty times (individual lines) to incorporate uncertainty around the age of the fossil occurrences. b Mean rate of diversity change (slope in species per 0.1 Myr) in the last twelve million years for the same coral families, calculated as the difference in diversity between subsequent time points (see Methods). Acroporidae—red; Agariciidae—brown; Merulinidae—yellow; Mussidae—purple; Pocilloporidae—green; Poritidae—dark blue. Source data are provided as a Source Data file.
