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 …

A Food Chain in a Fossil: A snake skeleton with its prey still inside!
The relationship between predator and prey is a primal one, and one that fires the curiosity of many fossil fans. We love paintings of Tyrannosaurus battling Triceratops or saber-toothed cats leaping onto the backs of ground sloths. And we can be pretty sure that those interactions happened based on TRACE FOSSILS, like tooth marks in Triceratops bones that match closely with tyrannosaur teeth. How …

A Tale of Two Crocs: Predators of Cretaceous Spain
I tried to google “crocodiles are living fossils,” to see just how commonly that expression was used in popular articles. There were indeed a few articles that referenced this idea, suggesting that croc fossils from 80 million years ago would look identical the skeletons they have today. However, most were news stories reporting various discoveries in the fossil history of crocodiles and their rel …

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: Dodos and the evolution of bird brains
If you wander into the basement of the Peabody Museum of Natural History at Yale University, and wander into the fossil collections, you will find a vast array of different dinosaurs dating back over 200 million years. However, just a few feet away from the oldest dinosaurs you will find several drawers filled with the bones of Raphus cucullatus: the dodo. These are not fossilized; the dodo has on …

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 …
