Summary
| Description |
English: Figure 1. Stage-by-stage diversity trajectories of marine genera (top panel) and families (bottom panel) derived from Sepkoski’s compendia. The Big Five Mass Extinctions, inferred from an analysis of the extinction rates (data not shown, but see Figures 2 and 3), are indicated by the arrows. They correspond to the times of largest diversity loss. Note that in the genus-level data the Devonian consists of two peaks, indicating that the Late Devonian is more complex than the other big extinctions. Figure modified from Sepkoski (1997). |
