Episode 14 Field Guide: The Art of Dinosaurs

Conjuring up extinct environments, museums, books, and documentaries rely on art to show extinct animals revitalized in their ancient surroundings. This type of educational reconstruction is called Paleoart (or Palaeoart for the UK inclined). They are usually striking portraits of the weird place this planet used to be. But, you look at an image of a roaming Tyrannosaurus rex without wondering, “How much of that is real?” How do we know its bulk, its color, its environment, or its behavior? Where does the science start and the art (and hypothesizing) begin? Julius Csotonyi, a Candian paleoartist, sat down with us to discuss how he assembles his images which are on display in natural history museums across North America and fill his recently published book, The Paleoart of Julius Csotonyi. A single landscape by Julius is a blend of the latest knowledge from paleontologists, zoologists, paleobotanists, geologists, and geochemists, and as new information is learned, he is ready to update his paintings and present the world with a more accurate glimpse into the ancient past.

Arctic Alligators!

After an exciting summer looking for fossils in Wyoming and New Mexico, Matt and Adam are back in action with a Past Time Video!

Adam is pretty excited about a study based on fossils from the far northwest of Canada, but Matt thinks Adam is losing his touch and is a little too excited about a handful of scrappy fossils. It turns out the scraps are key to unraveling the complicated history of alligators and Adam reminds Matt that not all important fossils are beautiful skeletons.

Today alligators are found in China and North America. But how did these freshwater-bound animals cross between the continents? Some animals made the same trek during the Ice Age, but that wouldn’t have been a great time for alligators to hop continents. A new discovery from a 50 million-year-old site on Banks Island, Northwest Territories, Canada may show alligators crossed between Asia and North America very early in the Age of Mammals. The fossils may not be much to look at, but fossils don’t always need to be pretty skeletons to tell paleontologists important details about the ancient Earth.

Episode 13 Field Guide: Following in the Footsteps of Dinosaurs

When we think of paleontologists, we think of people hunkered down with bones, teeth, and shells studying the preserved body parts of dead organisms. But animals leave behind more than just their skeletons. As they walk they can leave behind footprints, as they eat they can leave behind bite marks, and as they finish eating they leave behind…well…what comes from the behind. The study of the traces of past behavior is called ichnology and Dr. Tony Martin (@Ichnologist) and author of Dinosaurs Without Bones is with us to reveal all the amazing insights a paleontologist can learn from the fossil record, even when there aren’t any bones! He takes us through a wandering heard of sauropod dinosaurs, into the burrow of the dinosaur Oryctodromeus, and across the mudflats of an amphibian-dominated Alabama. These animals may be extinct, but their traces bring them back to thundering life in this episode of Past Time!

Episode 12 Field Guide: Growing up Dinosaur!

When we think of iconic dinosaurs, like T. rex with its massive head full of teeth, and Parasaurolophus crowned with a gigantic, tube-like crest, we’re thinking of the features of adult dinosaurs. But we know from looking around today that animals change a lot from birth to adulthood. Did T. rex always have a massive maw and Parasaurolophus a huge crest? How quickly did they grow in? What were they used for? To really understand the biology of these titans, paleontologists need to study baby dinosaurs to connect the dots from tiny hatchling to adult dinosaur. Unfortunately, the fossils of dino-toddlers are few and far between because their skeletons are usually pretty delicate. Plus, it can be very hard to tell what species of baby dinosaur you’ve discovered. In this episode we discuss the improbable discovery of a baby Parasaurolophus with Dr. Andy Farke, a paleontologist from the Raymond Alf Museum and Webb Schools in Clermont, California. Dubbed “Dinosaur Joe”, the young dinosaur was found and studied by young, high school scientists from the Webb School. The high school scientists were part of the team that revealed the six-foot-long animal was only one-year-old and had a little nubbin of a what would become that spectacular Parasaurolophus crest.
