Bargain, 5" Edmontosaurus Caudal Vertebra - South Dakota
This is a vertebra of a hadrosaur (Edmontosaurus annectens?) that was collected from the Hell Creek Formation of Harding County, South Dakota. Everything superior to the base of the pedicles has weathered away and wasn't recoverable. This bone is highly fractured and weathered, requiring crack repair in several spots. The lack of preservation detail makes it difficult to give a definitive genus identification.
Because of its age and sedimentary 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.
