Description
During the Cretaceous Period, North America flooded. The entire middle section of the continent was submerged, creating an inland sea that stretched from the Arctic to the Gulf of Mexico and hosted a unique and fascinating underwater ecosystem. Not only that, but it split west from east, creating two distinct "subcontinents." In this episode, we explore how this sea came to be, what lived within it, and what effect it had on land ecosystems of the time and the fossil record they left behind.
In the news: more crocs, the oldest fossils, a history of CO2, and unexpected fossil sex.
