The tracks of a hadrosaur (duck-billed dinosaur) at Dinosaur Ridge, Morrison, Colorado, USA. Visitors can see hundreds of dinosaur footprints along the ridge, just west of Denver, Colorado, USA. The tracks are in rocks from the Early Cretaceous Period. They have been darkened with charcoal to make them more easily visible. | |
