Episode 32 – The Changing Face of Crocodiles
Episode 32 – The Changing Face of Crocodiles INTRODUCTION TO GROWING UP – Every living thing grows up, and this episode of “Past Time” explores the evolution of the growing process. Specifically, we explore the evolution of growth in crocodiles, and how changes to the growing process at the earliest stages of crocodile development help produce the wide array of crocodile snout shapes we see today …

Episode 23: Meet the Echinoderms! Adventures with Ancient Sea Stars!
This episode was a blast to produce for a vertebrate scientist. I learned a ton about the echinoderms, the group of invertebrate animals to which sea stars, brittle stars, sea cucumbers, sea urchins, and crinoids belong. Be prepared for more adventures with invertebrate animals in the future. Engineering Echinoderms with Elizabeth Clark! Yale University Ph.D. student Elizabeth Clark, holding examp …

Episode 20: Digging the Dawn of Dinosaurs – Paleontology at Ghost Ranch
Hi all. Adam Pritchard here. I’ve been thinking about telling the story of my field experience in the Triassic-aged Chinle Formation of northern New Mexico for many years. The Hayden Quarry fossil site at Ghost Ranch has produced the best-preserved and most diverse record of American dinosaurs from the Triassic of North America, plus some of the strangest reptiles that ever lived. I’ve been proud …

Episode 16: Hunting Antarctic Dinosaurs
Erik Gorscak and Pat O’Connor, two paleontologists from Ohio University, are about to set out on an expedition to Antarctica to hunt for fossils from the end of the Age of Dinosaurs. They are part of a larger team called the Antarctic Peninsula Paleontology Project (AP3), an international collaboration of fossil hunters and geologists who are about to spend almost two months at the bottom of the p …

News Bite: The evolution of ornithischian dinosaur jaws and bites!
With Past Time, Matt and I tend to focus on the new discoveries in paleontology: the new species that show up in the news, or the important specimens discovered in museum collections. These are the raw materials that feed the fires of paleontology as a science. However, observation is only the first step in the scientific method: a method that paleontologists follow. This week’s episode features t …

News Bite: Kerberos! Giant mammal carnivore from after the Age of Dinosaurs!
It weighed twice as much as a modern wolf. It had three pairs of meat-slicing teeth. It was the first carnivorous land animal to reach 200 pounds on the entire continent of Europe after the extinction of the dinosaurs. And a team of European scientists and Past Time co-host Matthew Borths just introduced us to it. Ladies and gentlemen: meet Kerberos, monster mammal carnivore!

News Bite: Basilisks in the Old(er) West!
The oldest basilisk lizard from North America, described by Jack Conrad from NYIT College of Osteopathic Medicine, shows the 48 million year old animal was part of an ancient lush jungle ecosystem…in the middle of Wyoming. The beautifully preserved skull has important stories to tell about the evolution of the lizards most famous for their ability to scamper across the water, but it also reveals …
