Sobre el podcast
Join David and Will as they explore the paleontologists’ perspective on various topics in life and earth history. Each episode features a main discussion on a topic requested by the listeners, presented as a lighthearted and educational conversation about fossils, evolution, deep time, and more. Before the main discussion, each episode also includes a news segment, covering recent research related to paleontology and evolution. Each episode ends with the answer to a question submitted by subscribers on Patreon. New episodes with new topics every fortnight!

Why spend all that effort chasing after prey when you could just convince them to come to you? This episode, we explore the many and varied ways that predators lure their prey, from dangling lights to strategically-placed bait. And we’ll discuss the evolutionary pros and cons of this life strategy, and how all sorts of animals – and plants – make the most of it.
In the news: big Jurassic bugs, big Jurassic belemnites, ocean amphibians, and aquatic anatomy.

Welcome … to Cute-E!
During our Spook-E series, we speculate on the evolution of monsters from myth and popular media, but we leave out fiction’s more adorable creatures. In Cute-E, we choose cuddlier critters and discuss how they – or something like them – could evolve here on Earth, pulling inspiration from real-world species across our planet’s history. This year’s theme is Aliens!
This episode, we’re overrun with cuteness! What evolutionary history could lead to pesky swarms of irresistibly adorable fuzzballs? Our creatures to create this time: Tribbles.

Here on our blue-and-green planet, the green is plants. This episode, Aly joins us again to explore the beginnings of this all-important group of life. We’ll discuss which ancestors gave rise to true plants, what the fossil record tells us about the timing of this momentous event, and the array of key adaptations that allowed plants to join their fungus and animal cousins up on dry land.
In the news: mosasaurs, more mosasaurs, Jurassic mammals, and horned dinosaurs.

During the Cretaceous Period, while tyrannosaurs stomped around the northern continents, the less famous abelisaurs were the top predatory dinosaurs of the south. This episode, we piece together the history and diversity of these predators, and we explore what they were doing with their bulldog faces, tiny arms, and in some cases, horned faces.

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.

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 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.

Vipers include some of the world’s most specialized ambush hunters, and they are one of the most diverse and successful groups of snakes. This episode, we take a tour through the many visages of vipers, we explore their unique adaptations from head to tail, and we investigate the deep history that led them to their incredible modern success.

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.

This episode, we sample the species that have taken to a life of digging in the dirt – and elsewhere – why they do it and what physical adaptations help them along the way. Then, we’ll take a tour of burrows in the fossil record and explore what clues paleontologists can use to determine which ancient critter constructed a given burrow.

The world is full of food, but in order to make the most of it, living organisms need to be able to break it down and extract the useful nutrients. This episode, we explore the fundamental process of digestion and the many, many ways that life has adapted this process to various diets. And we’ll take a look at what the fossil record has to tell us about ancient diets and the evolutionary history of digestive systems.

For most of the Cenozoic Era, South America was home to an incredible group of predatory birds called phorusrhacids, which included some of the largest carnivorous birds of all time. With their giant axe-like beaks and powerful clawed legs, these giants have gained the nickname “terror birds.” This episode, we explore what makes these birds unique, how they varied across their diversity, and what exactly they were doing with all those terrifying tools.
In the news: a bitten plesiosaur, wildflower adaptation, a new croc, and dinosaur parents.

This episode, we’ll explore the regular traits that allow nocturnal animals to get by, we’ll discuss some of the ways nocturnal evolution has shaped living species, and we’ll investigate which – if any – of these traits we can identify in the fossil record.
