Diagnosis
ReferenceDiagnosis
R. Owen 1860Head defended, as in the Ganocephala, by a continuous casque of externally sculptured and unusually hard and polished osseous plates, including the supplementary "post-orbital" and "super-temporal" bones, but leaving a " foramen parietale." Two occipital condyles. Vomer divided and dentigerous. Two nostrils. Vertebral bodies, as well as arches, ossified, biconcave. Pleurapophyses of the trunk, long and bent. Teeth rendered complex by undulation and side branches of the converging folds of cement, whence the name of the order.
