This is a fragment of tibia from Edmontosaurus annectens, from the Hell Creek Formation, Dawson County, Montana. This section is 6.8" long and 6" wide. This specimen has preserved compact (cortical) bone and soft inner (marrow) bone. This comes from a bone that was weathering on the surface and too far gone to put back together.

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.
