This is a giant
, 21.5" tall dorsal vertebra of a duck billed dinosaur (Edmontosaurus annectens) from Bowman, North Dakota. It was collected within the last year from our partners lease, and just recently prepared.
It has the repair and crack fill restoration that is expected in a dinosaur bone like this. Most of the center process on the vertebra has been restored, along with the last 2 inches of the left process.
are frequently referred to as duck-billed dinosaurs and are members of the ornithischian family Hadrosauridae They were fairly common herbivores which roamed Asia, Europe and North America during the Upper Cretaceous Period. Many species of hardrosaurs had distinct crests on their head, some of which had air filed chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
Because of its age and sedimentary composition composition, the Hell Creek Formation has become one of the most paleontological 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, including 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.
