Bargain, 21" Hadrosaur (Edmontosaurus) Vertebra - Restored Processes

This is a 21" tall dorsal vertebra of a Hadrosaur (Edmontosaurus) from the Hell Creek Formation of Glendive, Montana. The centrum is well intact, though the cortical bone has weathered away from millions of years of erosion. The neural arch was found in several pieces and has been reattached to the centrum and repaired with spots of gap fill restoration. Some bone fragments of the vertebra superior to the neural arch were recovered, however they required significant restoration to put back in position. Each of the processes are completely restored hence the bargain price.

The entire vertebra measures 21 x 16.1 x 6.6". 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.
