14.6" Sub-Adult Hadrosaur (Edmontosaurus) Left Humerus - Wyoming

This is a 14.6" long humerus bone from the left arm of a sub-adult hadrosaur (Edmontosaurus annectens), collected from our partner's lease on the Lance (Creek) Formation in Niobrara County, Wyoming.

The bone was found heavily fractured and fragmented, requiring crack repair and glue stabilization in spots. Portions of the bone are missing through the diaphysis and distal epiphysis.

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.
