Skull: Three-/dimensional model of the skull of Bentonyx from CT scans, showing the teeth of the upper (blue) and lower (pink) jaws rooted deeply in the bone.

Section: Teeth of upper and lower jaws, X-ray section along the length of the jaws showing teeth in wear. Unerupted teeth at left are made from dentine (de) with an enamel (en) cap. Many teeth show the pulp cavity (pc) at the base. Tooth wear is so extreme that teeth are worn flat to the bone, and in many cases bone works against tooth in chomping.
