Bargain, 4.9" Hadrosaur (Edmontosaur) Dorsal Vertebra - South Dakota

This is a dorsal vertebra of a hadrosaur (Edmontosaurus) 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. The edges of the centrum are weathered, revealing the mineral replaced osteons and bone matrix within.

Comes with an acrylic display stand.

Hadrosaurs are frequently referred to as duck-billed dinosaurs and are members of the ornithischian family Hadrosauridae They were fairly common herbivores which roamed Asia, Europe and North America during the Upper Cretaceous Period. Many species of hardrosaurs had distinct crests on their head, some of which had air filed 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 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.
