2.3" Hadrosaur (Edmontosaurus) Ungual - Wyoming
This is a beautiful, 2.3" long ungual (claw) bone of a hadrosaur (Edmontosaurus annectens), collected from our partner's lease on the Lance (Creek) Formation in Wyoming. The bone has not been repaired or restored.
Hadrosaursare 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.
