7.2" Hadrosaur (Edmontosaurus) Right Surangular Bone - Montana
This is a 7.2" long surangular (skull) bone from the right side of the skull of the famous hadrosaur, Edmontosaurus annectens. Portions of the bone are missing, but it is overall intact with nice bone preservation. The bone was collected from a private lease in Dawson County, Montana. It's from the Hell Creek Formation, making it approximately 66 million years old.
Comes with the pictured metal display stand.
The surangular bones were located at the posterior end of the skull, just behind the dentary and beneath the quadrate bone.

About Edmontosaurus
Edmontosaurus is one of the largest Hadrosaurs, and one of the most widespread: fossil remains have been 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 its first fossils 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 to 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.
