is a jaw section Edmontosaurus annectens of a Hadrosaur, often referred to as a duck-billed dinosaur. You can see the grooves where three of it's teeth would have been rooted. 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.

This jaw section was found in Carter County, Montana. The white coloration is due to bleaching from it being exposed near the surface.


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 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.
