The Oldest Known Sauropod Footprints in North America
St. George, Utah -- Nestled among the red cliffs, volcanic formations and ancient layer cake sediments of an American southwest desert landscape, the populous town of St. George, Utah, is best known for its imposing Mormon temple and sites representing Mormon pioneer history. But take a closer look, and you will find perhaps the largest collection of dinosaur footprints in the world. Housed in the newly constructed exhibition hall of the St. George Dinosaur Discovery Site at Johnson Farm, a huge, ever-expanding collection of natural cast dinosaur footprints, swimming marks, and tail-drag impressions will no doubt emerge as the world's premiere site for early Jurassic dinosaur prints. The exhibition also includes natural casts of mud cracks, actual dinosaur skin impressions, fossilized bones, and the impressions and remains of other lifeforms representative of the environment that existed here at that time. Of particular interest to the scientific community, the site presents the earliest known evidence of sauropod dinosaurs in North America, as well as a "virtual snapshot" of an Early Jurassic (195 million year old) lake ecosystem that existed when the American continent was part of the supercontinent called Pangea.
