Diagnosis.

Distinguished by the following combination of features: grooves on postorbital portions of frontals converging toward parietal foramen; maxilla extending posteriorly to level behind posterior orbital margin in lateral view; jugal excluded from orbital margin in lateral view; anterior palatal process of jugal extending far between maxilla and palatine; jugal extending posteriorly along anteromedial margin of subtemporal fossa; apex of posterodorsal process of epipterygoid exposed at dorsomedial corner of posttemporal fossa in occipital view; distinct ‘ epiotic’ ossification between supraoccipital and opisthotic; and palatine with three crushing teeth located posterior to two maxillary crushing teeth ( Rieppel 2001 a).
