Dinosaur Ridge, Morrison, Colorado, USA
Dinosaur Ridge, Morrison, Colorado, USA. Visitors can see hundreds of dinosaur footprints along the ridge, just west of Denver, Colorado, uSA. The tracks of duck-billed herbivores and ostrich-like carnivorous dinosaurs are in rocks from the Early Cretaceous Period. The tracks have been darkened with charcoal to make them easier to see., by JIM WEST/SCIENCE PHOTO LIBRARY
