We spend a huge portion of our lives sleeping. For us and other animals, it’s clearly a very important behavior. And yet, despite how familiar and commonplace it is, there’s plenty we still don’t understand about sleep: its origins, evolution, and even how to define it in the first place. In this episode, we explore some of the remarkable variation in animal sleeping habits, we discuss some of the ways we study and understand sleep, and we touch upon the crucial – and much debated – question of what sleep even does for us anyway.
In the news: early monotremes, chunky dunk, Permian pollinators, and parasitic ant mutations.

Once, it was a volcanic crater. Then, it was a lake, perhaps equal parts lush and deadly. Much later, it was a mining site. And finally, today, it is a UNESCO World Heritage Site and one of the most famous and heavily studied fossil sites in the world. In this episode, we discuss the history and formation of the Messel Pit, and we ooh and aah over a small sampling of the many thousands of incredible fossils that have been found there.
In the news: lacewing larvae, folding leaves, dinosaur growth, and ankylosaur sounds.

Giraffes are so famous and familiar to most of us that it can be easy to forget how utterly strange they are. This episode, we explore modern giraffes, their living cousins (okapis!), and their ancient relatives to understand how these monumental mammals came to be how they are. Along the way, we’ll meet a whole variety of wacky-horned fossil species, and we’ll tackle the questions of how and why the giraffe got its long neck.
In the news: dinosaur feet, marine crocs, hunted giant elephants, and bird egg evolution.

Happy Darwin Day!
You’ve seen his artwork. And if you somehow haven’t, you’ve seen lots of art inspired by his artwork. Charles R. Knight might be the most influential paleoartist of all time, inspiring a century’s worth of artists, scientists, and ancient-animal-enthusiasts around the world with his skillful and scientifically-informed works. In this episode, we explore who Knight was, how he became a renowned paleoartist, and his extraordinary role in ushering in the modern world of paleontology.
In the news: Arctic primate-cousins, oldest caecilians, diving bird evolution, and Jehol bird preservation.

Glowing organisms might seem like something out of science fiction, but not only do they exist here on Earth, they are incredibly common. Some species glow when exposed to certain kinds of light, and others produce their very own light in the darkest habitats on the planet. This episode, we explore glowing life: how they do it, what they use it for, and what we can tell about how this remarkable ability came to be.
In the news: painted turtles, dinosaur herbivores, human brains, and insect ears.

The Paleozoic Era was home to many strange and fascinating extinct groups, and among the most eye-catching of these were the eurypterids. Colloquially called “sea scorpions,” these carnivorous aquatic arthropods came in many forms for many habitats and are now known from many amazing fossils. In this episode, we discuss what makes eurypterids distinct from similar organisms, what we know about their lifestyles, and the many ways they continue to surprise and confuse us.
In the news: Brazilian crocs, injured cats, breeding ichthyosaurs, and mammal-munching dinos.

Happy New Year!
It’s been an exciting and eventful year for the podcast, and we’re glad you’ve been along for the ride! As usual, this is our annual Q&A where we answer the many, many questions our listeners submitted – the scientific, the silly, and the personal.
Thanks as always to all of our listeners, our Patrons, our special guests, and to everyone who supports the podcast in ways big and small.
See you next year.

It’s a great time of year to talk about conifers! Also their cousins: cycads, ginkgos, and others! Gymnosperms don’t get nearly as much love and attention as their flowering counterparts, the inescapable angiosperms, but they nonetheless have their own fascinating history going all the way back to some of the earliest forests on Earth. This episode, we’re joined once again by our favorite paleobotanist Dr. Aly Baumgartner to discuss what makes gymnosperms unique, what has made them so successful for hundreds of millions of years, and how these incredible plants have changed the world.
In the news: fossil-finding robots, super-old DNA, ankylosaur clubs, and snake sex organs.

Viviparity is the reproductive style where embryos develop inside a parent’s body instead of inside an egg the parent lays. It’s a very familiar habit to us placental mammals, but it’s also an extremely widespread and diverse feature of life. Seriously, it’s ridiculous just how many times viviparity has evolved and just how many different ways species have found to be viviparous. In this episode we’ll answer such questions as: How and why does viviparity evolve? What features vary from one viviparous group to the next? And how do we identify viviparous animals in the fossil record?
In the news: army ants, oldest lizards, beaver families, and swimming dinosaurs.

Built-in body armor is common among reptiles and rare among mammals, but armadillos are the major exception. Equipped with a full set of segmented armor over their heads, backs, and tails, armadillos have been waddling around well-protected for tens of millions of years, and their ancient relatives include some of the most famous and preposterous of extinct mammals. This episode, we discuss the unique features and fascinating history of armadillos, glyptodonts, and their other ancient cousins.
In the news: roots and extinction, new croc-like reptiles, early cooking, and giant turtles.
