Zuul Ankylosaur ungual

Extremely rare top quality ungual or hoof of an Ankylosaurus called Zuul crurivastator from the Judith River Formation. Zuul crurivastator was a large Ankylosaur which grew to 6 m or 18 feet. The body was covered with osteoderms or boney plates of protective armor, and had a clubbed tail for defense. Unguals of Ankylosaurs have a very specific detailed structure, very different from Hadrosaur unguals. Their structure is close to that of Triceratops but the shape of the Ungual is different. Very rare collectors item.
