6.2" Fossil Dinosaur (Hadrosaur?) Transverse Process - South Dakota

Fossil Dinosaur (Hadrosaur?) Transverse Process - South Dakota #145884

This is a 6.2" long dinosaur vertebra process (transverse) that was collected from the Hell Creek Formation in Harding County, South Dakota. There are crack repairs through the process, some of which required minor gap fill restoration. It somewhat resembles the transverse processes from the dorsal vertebra of a Hadrosaur.

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.
