4.8" Edmontosaurus (Hadrosaur) Vertebrae
This is a nicely preserved vertebrae of Edmontosaurus annectens a type of Hadrosaur (Duck-Billed Dinosaur) It was found in the Hell Creek Formation of Montana. The processes are missing and there is some erosion to the surfaces but it is very solid. It's in nice shape with the neural canal and part of the processes still intact, features that are often lost due to their delicate nature. There are a few repaired cracks to the process, but no restoration. A nice solid vert.
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.
