Fig. 1: Stage-level ammonoid sampling regions in the Late Cretaceous.
From: Late Cretaceous ammonoids show that drivers of diversification are regionally heterogeneous
Chosen regions corresponding to biogeographically distinct ammonoid provinces with sufficient data to derive spatially standardised subsamples for reliable estimation of diversification dynamics. The global dataset encompasses the grey points in addition to all coloured regional points. Source data is available in the electronic supplement accompanying this paper.
