Diagnosis
ReferenceDiagnosis
H. G. Seeley 1895Temporal vacuities roofed over, with the broad brain-case closed behind, as in Kistecephalus, by a vertical occipital plate. Skull bones thin, enclosing an interior cartilage. The palato-nares are placed far forward, without any indication of a hard palate forming a platfrom in front of them. The teeth appear to have been pointed.
