The Common Descent Podcast

This is a listener-requested topic and a guest episode! We are joined by super-special guest Michelle Barboza-Ramirez of the Femmes of STEM podcast, who is here to help us explore the deep subject of Women in Paleontology. We talk about female scientists past and present, discuss the challenges they face, and reflect on the broad questions of diversity in the field of paleontology and other sciences. In the news: baby saber-tooths; Triceratops brains; surprises in dinosaur poop; and super-ancient trilobite guts!

In the second part of our exploration of our own evolutionary past, we focus in on one particular recent group of big-brained, bipedal hominins. We explore their incredible diversity, their clever creations, and the origins of a species that we know better than any other. In the news: Neanderthal plaque; very surprising footprints; our tiny mysterious cousins; and an ancient sugary secret.

This time, by request, we discuss an ancient story so detailed, compelling, and important that we had to split it in two! In part one, we find our own place on the family tree of life, and trace the history and evolutionary innovations of our ancestors and cousins: the early hominins. In the news: four-flippered swimming; the life of a dodo; weird whale teeth; and the many possible paths of evolution.

In this episode, David tells tales of his trip to Calgary for this year’s SVP meeting: research presentations; meeting new people; paleo-field trips in Alberta; and more. If you’re into vertebrate paleontology, this is one of the biggest and more exciting events of the year! In the news: several hundred research projects presented by paleontologists from all over the world, who came together at the end of August for the annual meeting of the Society of Vertebrate Paleontology! We mention just a few of these studies.

This episode, by request, we’re talking about one of our favorite groups of invertebrates! Specifically, invertebrates with big brains and squiggly arms - some with beautiful shells and others with incredible camouflage - and a fantastically rich fossil record stretching back over 500 million years: the cephalopods. In the news: a giant gets a name; a confusing early dinosaur; some really old ice; and a rockstar croc.

This episode, we’re talking mass extinction again! Last time, we touched on the event that ended the Age of Dinosaurs, but this time – by listener request! – we’re discussing the event that started it: patterns and potential causes of the end-Triassic mass extinction. In the news: a colorful armored giant; a surprise apex predator; epigenetics and variation; and some fast-evolving big-headed geckos!

This episode, we finally take the time to talk in detail about the dig site we mention more than any other, the site where we both spent many years: the Gray Fossil Site! We discuss the site’s discovery, ongoing work, ancient ecosystem, and some of our own experiences. In the news: the speed of T. rex, warm-blooded evolution, dinosaur sails, and the earliest Australians.

And now for something completely different! Just how deep is Deep Time? Exactly how are important events arranged throughout our planet’s history? Which events are recent and which are ancient? In this special episode, we take a tour through Earth History, from beginning to end, one million years per second: a virtual trip through geologic time!

The episode comes to you from inside the fossil prep lab, where we explore what goes into cleaning, repairing, and generally making fossils ready for study. We are joined by our friend Shawn Haugrud, as well as two of his lab’s head preparators: Shayleigh Maden and Davis Gunnin! In the news: swimming strategies of plesiosaurs, surprise marine mass extinction, a bone-crushing Jurassic croc, and the temperature of dinosaur eggs.

This episode is about the history of the earth, and how we compile all that we know about the ancient past in the great Geologic Time Scale.    In the news: the shapes of bird eggs, very ancient amphibians, more dinosaur faces, and the history of hippos.
