Here we have a very nice jugal (skull part) of a juvenile Hadrosaurus coming from the Late Cretaceous Period in what is now known as the Hell Creek Formation about 70 million to 66 million years ago. Besides jaw sections, skull parts are hard to find as they are thin and easily damaged by erosion.

Edmontosaurus sp.
