Diagnosis
ReferenceDiagnosis
D. Pol et al. 2011Small heterodontosaurid (estimated body length of approximately 50–60 cm) with the following autapo- morphies: jugal with strongly developed, dorsally placed lateral boss; dorsal part of the postorbital process of the jugal very slender and flexes abruptly posteriorly at the beginning of the articular facet for the postorbital; forebrain facet on the ventral surface of the frontal enlarged and with significantly raised margins; posterior teeth with asymmetric arrangement of denticles and with a mesial concavity in which the distal margin of the preceding tooth is lodged; posteriormost dentary tooth “hand- shaped”, with only one or two mesial denticles, the most anterior of which diverges mesially from the mesial margin of the crown; presence of small crenulations along the cutting margin of each denticle.
P. C. Sereno 2012Heterodontosaurid ornithischian characterized by the follow- ing four autapomorphies: (1) external mandibular fenestra absent; (2) denticules on the margins of individual denticles; (3) mesially divergent basal denticle on mesial margin in some dentary crowns; (4) mesial denticulate margin approximately 60% the length of the distal margin.
