Fossil Hadrosaur Dinosaur Bone Sections - Hell Creek Formation

These are sections of fossil bone from hadrosaur (duck-billed) dinosaurs. They come from the Late Cretaceous-aged Hell Creek Formation of South Dakota, and are approximately 66 million years old. The majority of these specimens range from 1" to 3" with a few being up to 4", and the photos are representative of the specimen(s) you will receive.

Each specimen is accompanied by a description card. Quantity discounts are available.

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.
