Episode 252 - The Ice Age
About 10% of the Earth’s land surface is currently covered in persistent glacial ice, but for most of Earth history, that number was much closer to zero. This episode, we explore what happens when ice overtakes our planet and how we investigate icy conditions of the distant past, and we’ll take a close look at the most recent (and ongoing) global climate event that we commonly call the Ice Age. In the news: distant space objects, snake embryos, Jurassic chirps, and polar dinosaur nests.

Episode 251 - The Sun
The Sun is kind of a big deal. It is the center of our solar system, around which all other objects revolve, and its heat and light are responsible for the life-supporting conditions here on Earth. This episode, we take a close look at how the Sun actually works and what makes it different from other stars. Then, we track the lifetime of the Sun, exploring how it originally formed, how it has changed over its lifetime, and how it will eventually burn out. In the news: carnivorous plants, ancient burrowers, live birth, and reptile metabolism.

Episode 250 - Camels
Large, herbivorous mammals come in many shapes and sizes, but few are as famously unusual as camels. This episode, we explore the surprising adaptations of Old World and New World camelids, from the dromedaries of Middle Eastern deserts to the llamas of the Andean highlands. Then, we take a tour through their fossil record to investigate the many forms this family took on the way to our modern diversity. In the news: stomach stones, aquatic reptiles, tiny dinosaurs, and a Poop Explosion.

Episode 249 - Sexual Dimorphism
In most animal species, there are differences in the anatomy, behavior, and lifestyle of male and female individuals. In this episode, we explore the incredible variety of these differences and the equally incredible blurry areas between the sexes, we investigate the evolutionary processes behind these features, and we examine the constant and confounding discussion about whether or not we can spot sexual dimorphism in the fossil record. In the news: The Story of Birds, early snakes, and early archosaurs.

Episode 248 - Big Cats
Felines come in all shapes and sizes, but only a handful of them are large enough and in charge enough to have earned the title of “Big Cats.” This episode, we’re joined by special guest Lindsay Nikole as we take a tour through the surprising diversity of the “official” and “unofficial” big cats, and we explore how their evolutionary past has shaped this impressive assortment of apex predators. Find more of Lindsay here: https://www.youtube.com/@LindsayNikole And shout-out to the Cheetah Conservation Fund: https://cheetah.org/ In the news: giant sharks, early movements, Cretaceous fruits, and snake venoms.

Episode 246 - Gharials
Happy Croc Month! Most living crocodilian species look pretty similar overall – that’s why there are so many tips for telling alligators from crocodiles – but one group really stands out with their bulging eyes and remarkably slender snouts. This episode, we explore the various features and habits that make gharials unique among crocs, and which have caused no end of confusion for scientists trying to sort out their evolutionary history. And, of course, we’ll take a trip into the fossil record to visit some of the most extraordinary long-snouted crocs of the distant past. In the news: hagfish eyes, dinosaur arms, fungal spores, and fishing dinosaurs.
