Fig. 5: Taxonomic predictors of ammonoid extinction risk in the Late Cretaceous.
From: Late Cretaceous ammonoids show that drivers of diversification are regionally heterogeneous
The predictive effects of suborder and superfamily classification on ammonoid lineage extinction risk inferred from a multi-trait extinction model. Cells with crosses denote cases where there were no occurrences for a given clade in a region, either due to genuine absence or a lack of occurrences classified at genus or species level. Source data is available in the electronic supplement accompanying this paper.
