during the Cretaceous period. "We do know that during this time period, average temperatures globally were about 82 F (28.1 C), and the average tropical temperature was 93.5 F (34.2 C)," Hughes says.

Based on this new evidence, I further investigated the paleogeographical history of this region at the Late Jurassic-Early Cretaceous boundary in the hunt for Darwin’s 'small isolated continent'. The ...
