4.3" Long Edmontosaurus (Duck-Billed Dinosaur) Vertebrae - SD
This is a 4.3" long (including process) vertebrae of Edmontosaurus annectens, a type of Hadrosaur more commonly referred to as a "duck-billed dinosaur" . The vertebrae was collected from the Hell Creek Formation in Harding County, South Dakota. The top half of the process has been restored. The centrum is in really nice shape though with almost no erosion.
Hadrosaursare 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 Hadrosaurs had distinctive crests on their heads, some of which had air-filled chambers that may have produced a distinct sound. These crests may have been used for both audio and visual display purposes.
