Dinosaur, Colorado was originally named Artesia. As the town is located near Dinosaur National Monument (headquarters is located east of the town), the decision to rename the town for publicity’s sake was made. To further capitalize on this notoriety, streets are also named after dinosaurs, such as Tyrannosaurus Trail and Antrodemus Alley.
