Episode 91 - Frogs

Roughly nine out of ten living amphibian species are frogs. They’re incredibly diverse and successful, and they have been since the Jurassic Period. But the origins of frogs and their fellow modern amphibians is shrouded in mystery. In this episode, we discuss what makes frogs special, what their fossil record looks like, and what paleontologists know and don’t know about the earliest evolution of modern amphibians. In the news: colorful insects, salamander evolution, saber-toothed marsupials, and venomous caecilians?
