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.
