7.1" Articulated Ornithischian Dinosaur (Camptosaurus) Vertebrae -Wyoming
This is a 7.1" long string of articulated fossil ornithischian dinosaur (Camptosaurus sp.) caudal vertebrae, collected from the Late Jurassic-aged Morrison Formation in Wyoming. They were found naturally associated with each other and would have come from one animal.
A couple of the spinous processes remained intact, though each required some crack repair. Comes with an acrylic display stand.

About Camptosaurus
Camptosaurus was a medium-sized herbivorous dinosaur that lived during the Late Jurassic, approximately 155-145 million years ago. Fossils of this ornithopod are best known from the Morrison Formation of the western United States, where it shared its environment with dinosaurs such as Allosaurus, Stegosaurus, and Apatosaurus. Camptosaurus had a relatively robust body, powerful hind limbs, shorter forelimbs, and a beaked skull adapted for cropping vegetation. It was capable of moving on its hind legs but likely spent considerable time feeding on all fours. As an early member of the ornithopod lineage, Camptosaurus provides an important evolutionary link between more primitive ornithischians and the increasingly specialized iguanodontians that became prominent during the Cretaceous.

About The Morrison Formation
Located in the midwestern United States, the Late Jurassic-aged Morrison Formation is an incredibly large and fossiliferous formation that dates back to about 156 to 147 million years old. Named after the small town of Morrison, Colorado, the formation was discovered in 1877, and quickly became the center of one of the biggest rivalries in historical paleontology.
19th century paleontologists Othniel Charles Marsh and Edward Drinker Cope spent 15 years making outstanding strides in the discovery of fossils all throughout the American Midwest, but also resorted to unsavory methods in attempts to discredit or ruin the other's work and reputation, including destruction of specimens.
The total area of the formation is roughly 600,000 square miles, but much of that is inaccessible, deeply buried under prairie land and eroded during the formation of the Rocky Mountains. Even so, many outcroppings across the Front Range and upper Midwest allow paleontologists access to a wealth of information from Late Jurassic North America.
Dinosaurs from the region include large allosaurid dinosaurs, such as the eponymous Allosaurus and its larger relative Saurophaganax. Both exceeded 30 feet in length, making them some of the largest carnivores of their time. They competed with the similarly large megalosaurid Torvosaurus, and the somewhat smaller horned ceratosaurid, Ceratosaurus. On the smaller end of the theropod family tree was the raptor-like Ornitholestes.
For herbivores, Stegosaurus guarded their herds with huge, intimidating backplates and formidable tail spikes. Small, early ankylosaurs like Gargoyleosaurus would have fed on the forested understory, smaller in size than the 30+ foot giant Stegosaurids.
However, the Morrison Formation's main attraction were the giant sauropod dinosaurs, some of the most colossal of dinosaurs and largest land animals of all time. Diplodocus, Camarasaurus, Apatosaurus, Brontosaurus, Brachiosaurus, Barosaurus, and Supersaurus all count themselves among these long-necked titans. None of these herbivores would have been less than 50 feet in length at adult size: the largest of their number would have exceeded 100-115 feet in length, and over 40 tons. For so many sauropods to have lived in roughly the same place and time, they all likely developed different feeding and living strategies to minimize competition. Their massive sizes and herds would have defended them well from any of the numerous predators of the Morrison.
