2.8" Fossil Dinosaur (Edmontosaurus) Ungual Bone - Montana
This is an ungual (claw bone) from a Hadrosaur (Edmontosaurus annectens) that was collected from the Hell Creek Formation on a private lease in Dawson County, Montana. The point of articulation has undergone some restoration and the edges have undergone some crack repair and gap fill restoration as well. The bone measures 2.5" long by 2.8" wide and comes with an acrylic display stand.
Edmontosaurus had four digits with the second and third ending in unguals. An ungual is a highly modified distal toe bone which ends in a hoof, claw, or nail. Elephants have ungual phalanges, as did the sauropods and horned dinosaurs.

Hadrosaurs
are frequently referred to as duck-billed dinosaurs and are members of the Ornithischian family Hadrosauridae. They were fairly common herbivores that roamed Asia, Europe, and North America during the Upper Cretaceous Period. Many species of Hadrosaurs had distinctive crests on their heads, some of which had air-filled chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
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.
