is a 4.8" long jaw section Edmontosaurus annectens of a Hadrosaur, often referred to as a duck-billed dinosaur. You can see the grooves where nine of it's teeth would have been. Hadrosaurs are believed to have the most teeth of any known dinosaur, some species having as many as 900 small teeth in their mouth which would have been used to grind vegetation.

The bone is solid and was collected this summer from the Hell Creek Formation in Powder River County, Montana.

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.
