St. George Dinosaur Discovery Site at Johnson Farm


About Us

The St. George Dinosaur Discovery Site at Johnson Farm (SGDS) preserves and exhibits fossils from southwestern Utah, particularly from an Early Jurassic, 200 million-year-old, lake ecosystem. The permanent displays feature the wide variety of tracks found on site, such as large and small dinosaur tracks, early crocodilian tracks, and invertebrate traces and burrows. Other fossils found and displayed in the museum include fishes, plants, and sedimentary structures. Uniquely, the museum was built directly over the initial discovery site, preserving a large section of the track surface.
The SGDS is operated by the DinosaurAh!Torium Foundation, a non-profit organization formed when the tracks were first discovered in 2000. The Foundation focuses on updating the site through special exhibitions and major building projects each year.
Besides the exhibits, the SGDS provides visitors with an introductory video and a self-guided tour translated into a variety of languages. For younger visitors, SGDS offers a “Junior Paleontologist Scavenger Hunt” and prize, a dig-for-tracks sandbox, and a hands-on activity area.
