4" Fossil Dinosaur Caudal Vertebra - Montana

Fossil Dinosaur Caudal Vertebra - Montana #320493

This is a 4" tall dinosaur caudal vertebra, collected from the Late Cretaceous Hell Creek Formation in Fallon County, Montana. Isolated vertebrae can be difficult to identify, especially when they have unusual morphologies. The oval shape of the centrum is fairly uncommon, hence our genus/species uncertainty.

Comes with an acrylic display stand.

There is a glue stabilized crack through the centrum and a repair through each pedicle. The spinous process has several repaired cracks and areas of gap fill restoration.

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.
