The Stegosaurus is Colorado’s state fossil, first excavated from Dinosaur Ridge in Morrison. It’s a Jurassic creature we are still learning about. In this Bonus pre-season episode, we explore how the Stegosaurus used its mighty spiked tail, and imagine what it may have sounded like. We also talk with Colorado’s mitigation paleontologist about fossil finds near road construction sites - and what happens with those with those fossils.
