5.7" Edmontosaurus Cervical Vertebrae Process
This is a 5.7" wide, process of a cervical (neck) vertebrae of Edmontosaurus. It was found in the Hell Creek Formation of South Dakota. The processes are for the most part, intact and have beautiful preservation. There are several repairs and some gap fill restoration, particularly around the vertebral foramen. Many of the repaired cracks are throughout the processes where they broke, likely from surrounding rock stress. Much of the centrum of the vertebrae is weathered away.
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 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.
