1.3" Fossil Crocodylomorph Vertebra - Montana
This is a beautifully preserved crocodylomorph vertebra that was collected from the Hell Creek Formation near Dawson County, Montana. There are three different crocodilian genus' that have been discovered in Montana within the Hell Creek Formation, making it difficult to assign these vertebrae to a specific genus.
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.
