27.4" Fossil Hadrosaur (Edmontosaurus?) Femur - Montana
This is a 27.4" long duck-billed dinosaur femur bone, collected from the Hell Creek Formation in Montana. This bone was reportedly identified as a Parasaurolophus femur from the Hell Creek Formation, however, there is currently no evidence that Parasaurolophus occurs within this formation. It is possible that the specimen originated from an underlying deposit of older Late Cretaceous age, potentially within the 73–76 million year range, though this would not confirm the identification as Parasaurolophus. Given the reported locality and the relative abundance of hadrosaur material from the Hell Creek Formation, an attribution to Edmontosaurus is considered more plausible.
Upon request, a custom metal stand can be built for this bone. Please contact support@fossilera.com for a price quote.
Approximately 90% of the bone is present, with a good chunk of the proximal epiphysis missing. There are several repaired cracks through the diaphysis, some of which required gap fill restoration. The most significant area of gap fill restoration is through the middle of the 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.

The Hell Creek Formation
Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
