At The Utah Field House of Natural History State Park Museum visitors of all ages can see and learn about real dinosaur fossils and what life was like millions of years ago. The museum features an extensive collection of dinosaur fossils from several different dig sites in Utah, including a 90-foot long Diplodocus skeleton, Brontotherium, Stegosaurus, and more! Besides the skeletons on display, you will also see ancient plant fossils, providing clues to what Vernal and the rest of Uintah County, Utah was like millions of years ago when most of the area was covered by water.
