Fig. 1: Latest Cretaceous (Maastrichtian, 70 Ma) paleogeography16 with a shallowed Central American Seaway (CAS) applied as a boundary condition in the Earth System Model simulations and interpolated to a resolution of 360 ×180°.

The geological sections analyzed in this study are indicated by large stars: (1) Sidi Ziane section in Algeria; (2) Re-2 core from the Negev region in Israel, both within the Western Tethys (WT); and two boreholes: (3) 6711/4-U-1 and (4) 6707/10-1, from the Greenland-Norwegian Seaway (GNS). Small stars represent additional published palynological data from locations such as (5) Barents Sea in the GNS; (6) Bass River south of the Hudson Seaway (HS); (7) Guatemala in the CAS; and (8) Bajada del Jagüel, Argentina, in the western South Atlantic (wSA). Remaining abbreviations: WIS – Western Interior Seaway, pNA - proto-North Atlantic, ArO - Arctic Ocean. The red dashed contour and black frame indicate A the area analyzed in the Earth system model simulations, encompassing the Western Tethys, Atlantic, and Arctic oceans, and B the analyzed region of the proto-North Atlantic.
