Sinopse

Past Time is a podcast that explores how we know what we know about the past. There's a special focus on the fossil record - it is hosted by two paleontologists - but delving into the story of the past isn't limited to dry bones. Today's paleontologists use techniques drawn from other sciences including Physics, Chemistry, Geology, and Biology to figure out what extinct animals were like and how they lived. Whether you are just starting to learn about the amazing animals that have called this planet home, or you have been fascinated by fossils for a long time, we hope you will join us as we dig into past times.Keywords: Paleontology, Dinosaurs, Mammals, Reptiles, Birds, Animals, Fossils, Extinction

    Of Collective Behavior and Trilobites Reading scientific papers can be a daunting prospect. Even the titles can contain layers of jargon. On Past Time, we work diligently to break down the barriers of science to make the discoveries of science for audiences of all ages. In this episode, we experiment with a new method: breaking […] The post Episode 34 – March of the Trilobites appeared first on Past Time Paleo.

    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 […] The post Episode 31 – The First Frogs of the Age of Dinosaurs! appeared first on Past Time Paleo.

    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 dinosaurs have […] The post Episode 29 – First of the Four-Footed Giant Dinosaurs! appeared first on Past Time Paleo.

    First Iteration I (Adam) am both proud and nervous to say that this is an atypical Past Time episode, as we’re not talking about a new discovery nor a real scientific topic; it is a recap/review of Jurassic World 2.

    Eighty million years ago, a wildly ornamented species of horned dinosaur roamed the southern half of North America’s western landmass, Laramidia. In 2016, paleontologist Eric Lund and his colleagues named it Machairoceratops cronusi, and we fell in love with this ceratopsian from Utah with hooks over its frill. In 2017, the site where Machairoceratops was […] The post Episode 27 – Machairoceratops: An Extinct Horned Dinosaur Under Threat! appeared first on Past Time Paleo.

    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.

    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 […] The post Episode 22: Matheronodon, a new dinosaur with a different kind of bite! appeared first on Past Time Paleo.

    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 […] The post A Food Chain in a Fossil: A snake skeleton with its prey still inside! appeared first on Past Time Paleo.

    Growth is a universal facet of all organisms that have ever lived, but figuring out how old they grow isn’t always easy. A new study examined the growth in one of the biggest predatory fish in all the ocean, the Greenland Shark (Somniosus microcephalus), revealing it to be the vertebrate species with the longest lifespan: nearly […] The post Grandma Sharkie: The Greenland Shark is the World’s Oldest Vertebrate Animal! appeared first on Past Time Paleo.
