27.6" Fossil Hadrosaur (Edmontosaurus) Left Ulna - Wyoming

This is a 27.6" long ulna (distal arm) bone of a hadrosaur (Edmontosaurus annectens), collected from our partner's lease on the Lance (Creek) Formation in Niobrara County, Wyoming. It would have come from the left arm of the hadrosaur.

There are several repaired cracks through the diaphysis of this bone, most of which required some minor gap fill restoration where the bone fragmented and crumbled away. There is crack repair and gap fill restoration through both epiphyses as well.

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.
