A Symbols indicate all fossil occurrences between Margaritatus and Bifrons ammonite (time) zones, grouped into regions (coloured, and labelled) by hierarchical clustering based on occurrence paleocoordinates. Values in the legend are total number of occurrences per region. Paleocoordinates, maximum sea level coastlines (thin black lines), and deeper waters (dark blue, demarcated by −1400 m contour) were reconstructed according to Pliensbachian (185 Ma) palaeogeography of the PaleoMAP model80. The landmass of Iberia is labelled. B An example of the utilized CLIMBER-X downscaled mean summer sea surface temperatures (SST) at the 185 Ma (Pliensbachian) paleoconfiguration and 750 ppm atmospheric CO2. Global location shown as box in world map (inset top left) alongside lines of paleolatitude every 30 degrees including the equator.
