Figure 4

Paleogeography of western North America during the Middle to Late Jurassic, featuring the transgression and retreat of the Sundance Sea and the subsequent development of the Bighorn wetlands. The graph on the lower right indicates the temporal extent of the Bighorn wetlands37 and the corresponding peak in the speciation rate (blue) (see also Fig. 1). Map was generated in R v. 4.1.2 (https://www.r-project.org/) based on polygons from Ref.27. The extent of the Bighorn wetlands follows Ref.72.
