Figure S1 from Identifying the most surprising victims of mass extinction events: an example using Late Ordovician Brachiopods

Histograms showing frequency distributions of simulated Foliomena fauna genus extinctions for each background interval model. In each sampling iteration, 112 genera were randomly drawn using per-genus expected risk estimates from the associated background model as sampling probabilities. 10,000 iterations were performed for each model. Red arrows indicate the number of Foliomena fauna extinctions observed during the latest Katian.
