5.4" Hadrosaur (Edmontosaurus) Caudal Vertebra w/ Stand - Montana

Hadrosaur (Edmontosaurus) Caudal Vertebra w/ Stand - Montana #245943

This is a beautifully preserved, 5.4" tall proximal caudal vertebra of a hadrosaur (Edmontosaurus annectens), collected from the Hell Creek Formation in Fallon County, Montana. The bone preservation is excellent with an intact neural canal, natural prezygapophyses, and bony landmarks still visible around the entire specimen.

It stands 9.5" tall on the pictured custom metal display stand.

The spinous process and transverse processes are broken at the base. The right transverse process has a repaired crack along the centrum and the broken base of the right transverse process has been stabilized with glue.

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.

Because of its age and sedimentary composition, the Hell Creek Formation has become one of the most paleontologically 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, 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.
