Near the close of the third great age of Dinosaurs, the Cretaceous Period, a large inland sea stretched across the midsection of North America lapping the sandy beaches of a shoreline that stretched along what is now the Front Range of the Rocky Mountains. Herds of quadrupedal, Ornithopod dinosaurs migrated north and south along the edge of the sea leaving their footprints in the wet sand. Quick, hungry meat-eating Theropod dinosaurs, darted on two legs, in and out among these herds looking for prey, leaving slender claw-tipped tracks. Evidence of this age-old drama is recorded in the stone west of Denver, Colorado in the steeply dipping strata that forms the Hogback at Dinosaur Ridge.
