Colorado's Secret Fossil Beds And Dinosaur Tracks

Colorado’s most accessible fossil beds and dinosaur tracks are split between two very different experiences: Dinosaur Ridge near Denver for footprints and bones, and Picketwire Canyonlands in the southeast for one of North America’s largest track sites. Florissant Fossil Beds, despite its name, preserves 35-million-year-old insect and plant fossils and petrified redwood stumps—not dinosaurs, which had died out long before that site formed.
