Diagnosis
ReferenceDiagnosis
P. Godefroit et al. 2017Rhabdodontid ornithopod characterized by the following autapomorphies: enlargement of both maxillary and dentary teeth (up to 5 cm in mesio-distal length); reduction of maxillary tooth families (4 per generation in MMS/VBN-02-102); interalveolar septa on the maxilla alternately present or resorbed ventrally, so that one functional tooth is lodged in two paired alveoli; shortened rostral process on the maxilla; broad dorsal shelf along the rostral third of the maxilla; more than 25 vertical and parallel ridges on the labial side of the maxillary teeth.
