Diagnosis
ReferenceDiagnosis
H. Zaher et al. 2006The lacrimal is barely exposed on the lateral surface of the snout, the ectopterygoid contacts the jugal and the maxilla extensively on its lateral edge, forming the medial border of at least the last maxillary alveolus on a ventral plane; dentary rami forming a mandibular symphysis that projects anteriorly to form an elongated and spatulated process with parallel lateral edges; there are four premaxillary, five maxillary, and nine dentary teeth that are characterized by their heterodonty; most dentary and maxillary teeth with anastomosing longitudinal striations formed by enamel ridges; well-developed serration of the mesial and distal margins of the crown; and one to six longitudinally aligned tubercles at the base of each crow, which can be well developed and ornament the whole surface of the crown base.
