9.8" Hadrosaur (Edmontosaur) Caudal Vertebra - Montana

 
 
 
 
 
This is a caudal vertebra of a hadrosaur (Edmontosaurus) from the Hell Creek Formation of Glendive, Montana. It is in good condition with wear around the edges. The vertebral arch and spinous process are both present. There are stress fractures through the centrum, the vertebral arch was found broken off of the body of the vertebra and has since been repaired with some gap fill and there are two repaired cracks through the spinous process with some restoration between the vertebral arch and process. The centrum of the vertebra measures 3.7 x 3.6 x 3". The entire vertebra when sitting in its anatomically accurate position, measures 9.8 x 8.7 x 3.6".

This specimen is accompanied by a custom metal display stand.

Hadrosaurs 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.
