This is a large, 4" long Metatarsal (toe bone) of a Edmontosaurus annectens from the Hell Creek Formation in South Dakota. The bone is in great shape with very little surface erosion. There are some cracks in it, but it's solid and has not needed to be repaired or restored. For more information check out A Detailed Guide to a Hadrosaur Foot at Smithsonian.com

Hadrosaurs

are frequently referred to as duck-billed dinosaurs and are members of the Ornithischian family Hadrosauridae. They were fairly common herbivores that 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.
