About
Dinosaur Ridge is where ancient history comes to life.
Nestled just west of Denver, Colorado, Dinosaur Ridge is a globally renowned National Natural Landmark, celebrated for its exceptionally preserved dinosaur bones and footprints. This unique outdoor museum offers an unparalleled opportunity to explore the remnants of ancient life directly embedded in the landscape, providing a tangible connection to the Jurassic and Cretaceous periods. Designated as the #1 dinosaur tracksite in North America by paleontologists, it’s a site where significant discoveries, including the first-ever Stegosaurus and Apatosaurus fossils, helped spark the "Bone Wars" of the late 19th century.
The main attraction is the Dinosaur Ridge Trail, a paved path featuring over 15 interpretive sites that guide visitors through a landscape rich with paleontological wonders. Along this trail, you'll encounter the Main Tracksite, showcasing hundreds of tracks from a variety of dinosaurs like Iguanodon-like ornithopods, bird-like ornithomimids, formidable theropods, and even ancient crocodilians. Further along, the Dinosaur Bone Quarry reveals exposed bones of Stegosaurus, Apatosaurus, and Allosaurus, which visitors can even touch. Beyond the fossils, the ridge itself is a geological marvel, displaying ancient ripple marks from a vast inland sea and a distinct volcanic ash bed, offering a multi-layered journey through Earth's past.
A visit to Dinosaur Ridge is an immersive educational adventure, perfect for curious minds of all ages. Whether you opt for a self-guided walk, a guided bus tour, or an expert-led geological expedition, the site's interactive exhibits at the Main Visitor Center and Martin G. Lockley Discovery Center, along with engaging activities like kids' dig areas, make the experience memorable. This easily accessible natural wonder allows you to literally follow in the footsteps of prehistoric giants, making it a must-see for anyone fascinated by dinosaurs and Earth's ancient history.

Dinosaur Ridge's rich history began in 1877 when Arthur Lakes, a clergyman and amateur paleontologist, discovered the first dinosaur bones in the Morrison Formation on the west side of the ridge. These groundbreaking finds included the world's inaugural Stegosaurus and Apatosaurus fossils, prompting prominent paleontologist Othniel Charles Marsh to initiate excavations and contributing to the famous "Bone Wars." Decades later, in 1937, during the construction of Alameda Parkway, workers accidentally uncovered a remarkable collection of dinosaur tracks on the east side of the ridge. Recognizing its immense scientific value, the site was designated a National Natural Landmark by the National Park Service in 1973. To ensure its preservation and promote education, the non-profit Friends of Dinosaur Ridge was established in 1989, and they continue to manage and protect this extraordinary paleontological treasure.
