8.4" Juvenile Dinosaur (Thescelosaurus) Humerus Bone - Montana
This is an 8.4" long, juvenile Thescelosaurus humerus (upper arm) bone from the Hell Creek Formation in Dawson County, Montana. There is significant gap fill restoration through the diaphysis of the bone, where it was found fragmented within the surrounding rock. Both the proximal and distal epiphysis are weathered, but required no repair or restoration.
This bone measures 8.4" long, with a 2.3" wide proximal end and 1.6" wide distal end. Comes with a riker mount case for display.

About Thescelosaurus
Thescelosaurus was a small ornithopod dinosaur that appeared at the very end of the Late Cretaceous period in North America. Many specimens' preservation and completeness indicate that Thescelosaurus may have preferred to live near streams.
This bipedal ornithopod is known from several partial skeletons and skulls, all of which indicate adult lengths between 2.5 and 4.0 meters (8.2 to 13.1 feet) on average. It had sturdy hind limbs, small wide hands, and a head with an elongated pointed snout. Their teeth and jaw morphologies suggest a primarily herbivorous diet.

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.
