One of the dinosaur foot prints.

The best preserved and most numerous of the dinosaur tracks today form the in-place trackway and exhibits of the St. George Dinosaur Discovery Site at Johnson Farm. Many other fossils, including bones of dinosaurs and fish, shells of small aquatic animals, and leaves and seeds of plants, have joined the footprints to enable paleontologists to reconstruct the nearly 200 million year old ecosystem preserved here with unprecedented clarity, an extreme rarity for rocks of any time period. This is a really neat place to go and visit. You get to look at the dinosaur prints up close.
