The rich paleontology of Colorado captures nearly the entire evolutionary history of dinosaurs, ranging from their first appearance in the Triassic to the last dinosaurs of the Cretaceous. Among them are legends like Stegosaurus[ital] and Allosaurus[ital], so abundant in Colorado quarries they became the target of the late 1800s "Bone Wars." Rocks preserved along the Front Range capture a once subtropical landscape, home to Tyrannosaurus Rex[ital] and Triceratops[ital] and many more, along with the best evidence we have to explain their sudden disappearance. Ongoing research continues to reveal secrets of Colorado's prehistoric past. Join Dr. Joe Sertich, Curator of Dinosaurs at the Denver Museum of Nature and Science, to explore the dinosaurs in our backyard and the history of major fossil finds across Colorado.
