Dinosaur footprint at Red Gulch Dinosaur Tracksite.
Red Gulch Dinosaur Tracksite is an assemblage of fossil dinosaur footprints discovered in 1997 on public land near Shell, Wyoming by Erik P. Kvale, a research geologist from the Indiana Geological Survey. The tracks are believed to have been made during the Middle Jurassic Period, 160-180 million years b.p., on what was then a shore of the Sundance Sea. Theropod tracks are thought to be among those discovered, but evidence suggests that the tracks were made by a large, diverse group of dinosaurs. The site is managed by the Bureau of Land Management as part of the Red Gulch/Alkali National Back Country Byway and is open to the public.
