Early Cretaceous/Late Jurassic Cartography

As mentioned in yesterday's post, the Map of the "Known World" was likely based on a map of our own world from "Continents in Collision" (1983), a Time Life book in the Planet Earth series.

The text accompanying the illustration states:

By 135 million years ago, the breakup of Pangaea was well under way.  Rifting and sea-floor spreading opened the nascent North Atlantic Ocean between North America and the old continent of Gondwana, in which South America and Africa were still joined.

As research in paleogeography advances, information on Jurassic climate patterns has emerged:


Jurassic climate patterns, from this paper.


It's interesting to note that the climate of the region corresponding to the Sea of Dread was indeed tropical, while the region corresponding to the Savage Coast is named the "Hispanic Corridor".
