Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| O. Rieppel 2001 | Grooves on the postorbital part of each frontal converging toward the pineal foramen; maxilla extends backward in lateral view to level well behind the posterior margin of orbit; jugal excluded from the orbital margin in lateral view; anterior palatal process of jugal entering deeply between maxilla and palatine; jugal extending backward along the anteromedial margin of the subtemporal fossa (possibly also present in Cyamodus kuhnschnyderi); tip of the posterior dorsal process of the epipterygoid exposed at the dorsomedial corner of the posttemporal fossa in occipital view; occiput with a separate, heterotrophic "epiotic" ossification located between supraoccipital and opisthotic; three palatine tooth plates, located entirely behind the two maxillary tooth plates. |
