3.6" Hadrosaur (Edmontosaurus) Caudal Vertebra Centrum - Montana

This is a 3.6" tall caudal vertebra centrum of a hadrosaur (Edmontosaurus annectens) from the Hell Creek Formation in Fallon County, Montana. It comes with an acrylic display stand.

Everything superior to the pedicles weathered away and wasn't recoverable. There are two repaired cracks through the centrum.

Edmontosaurus is one of the largest Hadrosaurs, and one of the most widespread, with fossil remains of Edmontosaurus being found across western North America from Colorado to northern Alaska. This large herbivore was about the same size as the contemporary predator Tyrannosaurus, reaching 39 feet in length and an average weight of about 6 tons. Named after Edmonton, the capital of the Canadian province of Alberta where the first fossils of the animal were discovered, Edmontosaurus was a gregarious terrestrial herbivore that ground up low-lying plant material with its large battery of ever-restoring teeth. Numerous skin impressions and mummified specimens show us that Edmontosaurus had scaly skin, and its forelimbs were enclosed in a fleshy "mitten" serving a purpose similar to a hoof. Edmontosaurus was a member of the Saurolophine clade of Hadrosaurs, meaning they had little or nonexistent crests on the backs of their skulls.

Because of its age and sedimentary composition, the Hell Creek Formation has become one of the most paleontologically studied areas in the world. 158 genera of animals and 64 genera of plants are known from the formation and new discoveries are made frequently. In addition to Tyrannosaurs, Ceratopsids, and Hadrosaurs, the formation has yielded remains of amphibians, reptiles, lizards, snakes and turtles, fish and sharks, avian and non-avian dinosaurs, and mammals. The Hell Creek Formation gives the most complete understanding of the environment just before the Cretaceous-Paleogene extinction.
