While listening to Michael Savage, he was talking about how the climate was warmer 150 million years ago. Well, the first thing that came to my mind was to see where the contients were at the time. Found The Paleogeographic Atlas Project, University of Chicago, Global Paleogeography, Paleobotany, Paleoclimates. Now, 150 Million BCE would be approximately Jurassic. Check the layout of the planet at that time. Also read the original story. (Okay, it's the Cretaceous).
