Episode 146 - The Jurassic-Cretaceous Transition
Every period of geologic time is distinguished by its own environmental and ecological features, and every boundary between time periods is characterized by change. The boundary between the Jurassic Period and the Cretaceous Period is mostly marked by mystery. Was there a mass extinction? Were there catastrophic changes? Where even is the boundary exactly? In this episode, we’ll discuss the answers – or lack thereof – to these questions and more as we explore this surprisingly enigmatic time in Earth history.
In the news: croc conservation, diving whales, aquatic mammal-cousins, and sauropod feet.
