Warner Valley Dinosaur Track Site
Located in the Warner Valley area of Saint George, Utah, this dinosaur track site is popular with visitors for its easy access and quality of the trackways. The original number of tracks was thought to be only 161, but a site investigation in 2010 lead to the discovery of four hundred plus tracks and counting that are found in trackways or as isolated footprints. Some of the tracks are well preserved displaying toe pads and claw marks.
It is impossible to know for certain which dinosaurs made these tracks. The larger tracks are Eubrontes (you-BRONT-tees) while the smaller tracks are Grallator (GRAL-uh-tore). The terms Eubrontes and Grallator are ichnogenera. They are groups of dinosaurs categorized together from their assumed characteristics based on their fossilized footprints. The Grallator footprints at this site are attributed to coelophysid dinosaurs such as Megapnosaurus. The Eubrontes footprints are widely accepted as being produced by a Dilophosaurus sized theropod.
The tracks are on found on top of the Springdale Member of the Kayenta Formation, which makes them lower-Jurassic in age, or about 190 million years old. The rock in which they are preserved is fine-grained reddish-brown and white sandstone.
