These rare tracks are situated over hundreds of acres of public, private, and state land, and are known as: Red Gulch Dinosaur Tracksite (public land) Flitner Ranch Dinosaur Tracksite (private land) Yellow Brick Road Dinosaur Tracksite (state land) Click on above links for more information about these tracksites! These tracksites were discovered by members of our GeoScience Team. The discovery of these tracks is significant because: · They occur in the lower part of the Middle Jurassic Sundance Formation, and are approximately 167 million years old. The Sundance unit was once thought to have been totally marine in character. · Virtually nothing is known about North American dinosaurs from this period. · Many of the dinosaur tracks appear very bird-like. These tracksites represent a period of time during which bird-like dinosaurs were beginning to evolve and little is known about bird's primitive ancestors. Our GeoScience Team also discovered and studied additional dinosaur tracksite localities in the area. Known as the Gypsum Spring Dinosaur Tracksite, these tracks are in the Gypsum Spring Formation and are even older than the above noted tracksites. Comments from Unbiased Observers: Our thanks to Port Aransas Beach Bums for an excellent review of the Red Gulch Dinosaur Tracksite by respected scientists. Members of the Beach Bums visited Shell during the summer of 2000, camping at the Shell Campground while visiting with our staff members and scientists.
