Red Gulch Dinosaur Tracksite
Bureau Of Land Management · Shell, Wyoming
A Bureau of Land Management site in the red badlands south of Shell where hundreds of dinosaur footprints, left about 167 million years ago on what was then a tidal shoreline, are exposed in a flat bed of limestone. Found in 1997, it upended the belief that the area was under open sea at the time, and it is one of very few tracksites of that age anywhere. A boardwalk and signs lead across the tracks; access is on a gravel back-country byway that becomes impassable when wet. The tracks are in rock of the Middle Jurassic Sundance Formation, about 167 million years old, from a time when the area was a shoreline. They were discovered in 1997 and are managed by the Bureau of Land Management.
