Late Jurassic, 145 million years ago (Morrison Formation). The Stegosaurus, the state fossil of Colorado, is eating the plants in the area of Dinosaur National Monument in northwestern Colorado and Northeastern Utah. No grass or flowering plants existed at this time, and many plants of the Jurassic plants will be extinct by the end of the age of dinosaurs (Cretaceous).
Plants depicted: Bennettite bushes (Zamites arcticus), Tree ferns (Cladophlebis sp.)
Animal depicted: Stegosaurus stenops
