Episode 31 – The First Frogs of the Age of Dinosaurs!

THE FIRST FROGS OF NORTH AMERICA Every discovery we make in natural history happens thanks to specimens. Fossil bones, shells, footprints, coprolites, tissue samples—even field notes and photograms—are the building blocks scientists use to tell the story of life on our planet. On Past Time, we talk a LOT about the contributions of museums and scientists to the story of life. However, we don’t ofte …

Episode 29 – First of the Four-Footed Giant Dinosaurs!

Ledumahadi and the first dinosaur giants The sauropod dinosaurs—the classic long-necks—included the largest land animal species that have ever lived. Throughout the Jurassic and Cretaceous, multiple families of sauropods achieved body masses over 50 tons: greater than any modern elephant and even exceeding the colossal indricothere rhinoceroses. Despite their incredible sizes, the sauropod dinosau …

Episode 26 – Colobops: the tiny reptile with a big bite!

Big bites come in small skulls This episode tells a story of one of Adam Pritchard’s favorite projects from Yale University, describing the skull of a teeny reptile from the early days of the Age of Reptiles. Hailing from the eastern coast of North America (present-day Connecticut), Colobops noviportensis had a skull only an inch long. However, intensive research and three-dimensional modeling rev …

Episode 25 – Ceratosaurs: Story of a Predatory Dinosaur Dynasty!

Masters of horns and teeth Throughout the Jurassic and Cretaceous Periods, dinosaurs were top dogs on every continent and in every sort of environment. The ceratosaurs were some of the classic predators that ruled the tops of the food chains for much of that time. Including classic predators such as Ceratosaurus, Carnotaurus, and Majungasaurus—as well as oddballs like Masiakasaurus, Limusaurus, an …

Episode 24 – Dinosaurs and crocodiles in the Land Before Egypt!

Egyptian paleontology has a long and storied history, although much of it is focused on discoveries from the Cenozoic Era. Incredible fossils of early whales, primates, and other mammals have been discovered in Egypt since the beginning of the twentieth century, work that continues to this day. However, fossils from the Age of Reptiles are much harder to come by. Indeed, most of the fossils record …

Episode 22: Matheronodon, a new dinosaur with a different kind of bite!

Matheronodon is certainly a dinosaur worthy of a bigger bite. With proportionally giant teeth strikingly different from the standard-issue ornithopod dinosaur, it is certainly one of the most important dino discoveries out of Europe this year. Better yet, the original scientific paper by Pascal Godefroit and colleagues is free to read in the journal Scientific Reports! If you’d like to learn more …
