Everybody poops! Throughout the history of life on Earth, animals of all lifestyles have been littering the planet with little presents, and those few that fossilize become coprolites: unique time capsules that can serve as invaluable sources of information, not just on obvious stuff like ancient diets, but also about evolution, extinction, and more. This episode: we talk turds.
In the news: de-escalating plant evolution, reverse speciation in ravens, upside-down dinosaurs, and record-keeping giant sponges.

In the earliest millennia of vertebrate life on Earth, the seas were home to the placoderms, a diverse group of extinct armored fish whose evolutionary innovations set the stage for some of the most important features of vertebrate life. This episode, we talk about some of history's most influential placoderms, with a special spotlight on the most famous of armored fish, the giant predator Dunkleosteus.
In the news: asteroids and volcanoes, running lizards, Shawn's turtle, walking fish, and more on broken mastodon bones.

In this episode, we firmly establish a tradition of extinction-talk! This time, by request, it’s the latest major prehistoric extinction in Earth history, the event that took from us the mammoths, ground sloths, and other giants of the Ice Age, a mass extinction that our own species was around to witness (and perhaps even cause): the Pleistocene Megafaunal Extinction.
In the news: mistaken Archaeopteryx identity, ticks with a taste for dinosaurs, evolution of the Tibetan Plateau, and ancient bear hibernation.
