Episode 174 - The Mesozoic Marine Revolution
01:59:04 Share

Earth’s oceans change over time, not just in their size and shape, but also in the very dynamics of their ecosystems. The stage was set for modern ocean ecosystems by an event called the Mesozoic Marine Revolution, a dramatic restructuring of ecology in shallow seas that saw the rise of many forms of active predatory lifestyles. This episode, we discuss the fossil evidence, the major players, and the ongoing and sometimes contentious research into this crucial period.

In the news: early arthropods, early apes, prehistoric ravens, and long-necked marine reptiles.
