Episode 211 - Edward Drinker Cope
7 days ago
7 days ago
E. D. Cope is one of the most recognizable and notorious names in paleontology history. He did some of the most important early work in vertebrate paleontology, he was one half of the dueling duo in the infamous Bone Wars, he named some of the most famous fossil animals, and he was profoundly irresponsible and unethical with his science. This episode, we’re joined by Astrid Lundberg to explore the life and legacy of Edward Cope, investigating such questions as: How did he get his start? What lasting contributions did he make to paleontology? And what was wrong with this guy?
In the news: giant small pterosaurs, plesiosaur skin, bat teeth, and African isotopes.

Episode 210 - Bones
Saturday Feb 01, 2025
Saturday Feb 01, 2025
The evolution of mineralized tissues is responsible not only for the incredible success and diversity of vertebrate animals, but also for their extraordinarily informative fossil record. This episode, we explore the detailed anatomy of bones and their deep evolutionary history, we touch on some of the ways they’re important for paleontology, and we take some time to discuss the secrets that can be found inside of ancient bones.
In the news: croc vs pterosaur, hominin diets, ears and gills, and reptile food.

Episode 209 - Chimaeras
Saturday Jan 18, 2025
Saturday Jan 18, 2025
You might know them as ghost sharks, rat fish, or spook fish. Chimaeras are close cousins of sharks and rays, equipped with distinctive and unusual features in their fins, teeth, and reproductive structures. In today’s oceans, chimaeras are rare and easy to miss, but their extended family includes some of the most diverse and iconic fish of the Paleozoic seas. In this episode, we’ll explore the traits that set chimaeras apart, we’ll take a tour through their ancient relatives, and we’ll investigate what their most famous cousins were doing with their strange spiral rows of teeth.
In the news: Baltic herrings, Cambrian arms race, pterosaur tails, and early dinosaurs.

Episode 208 - The Karoo Supergroup
Saturday Jan 04, 2025
Saturday Jan 04, 2025
Southern Africa is home to an incredible sequence of geologic formations that span more than 100 million years of Earth history. These rocks, collectively called the Karoo Supergroup, are an extraordinary resource for studying evolution and extinction across the Late Paleozoic and Early Mesozoic Eras. This episode, we’ll explore the deep history of this vast geologic resource, and we’ll sample some of the discoveries that have been made there.
In the news: dormancy evolution, Pangaean amphibians, regeneration genes, and Neanderthal fossil collectors.

Episode 207 - Therizinosaurs
Saturday Dec 21, 2024
Saturday Dec 21, 2024
Most theropod dinosaurs are sleek predators built for speedy movement and efficient hunting. Therizinosaurs are unusual. They’re slow and stocky and, in many ways, more like the famous plant-eating dinosaurs. This episode, we’ll explore the diversity of therizinosaurs, the winding path that paleontologists took to understand them, the many ways they became specialized for a diet of plants, and what was going on with those claws.
In the news: Parasaurolophus crests, Scottish bears, anglerfish evolution, and Clovis diets.

Episode 206 - Vestigial Structures
Saturday Dec 07, 2024
Saturday Dec 07, 2024
Evolution involves the innovation of new features, but even more reduction of old features. Those reduced features might disappear, develop in a new direction, or just linger as a functionless evidence of deep ancestry. This episode, we explore how we identify vestigial traits, how they help us understand evolutionary history, and the various evolutionary paths vestigial structures can take.
In the news: giant worm lizards, drumstick evolution, dinosaur poop, and pterosaur transitions.

Episode 205 - Parasitic Plants
Saturday Nov 23, 2024
Saturday Nov 23, 2024
Not all plants rely on the sun for their energy. Thousands of species are adapted for stealing nutrients from other plants. This episode, Aly joins us to explore the diversity and evolution of parasitic plants, their varied lifestyles, and their impacts on their hosts. We also examine the surprising nature of the parasitic plant fossil record.
In the news: a frozen sabertooth kitten, plesiosaur swimming, wing evolution, and dinosaur body armor.

Episode 204 - The Messinian Salinity Crisis
Saturday Nov 09, 2024
Saturday Nov 09, 2024
Around six million years ago, the Mediterranean Sea dried up, wreaking havoc with local marine life and leaving a dramatic legacy in the geologic record in the form of massive salt deposits. This episode, we’ll explore the evidence for this event, why it happened, how it ended, and the impact it left in the fossil record.
In the news: marine crocs, giant cicadas, giant tadpoles, and drowning bats.
