If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
R. J. Butler et al. 2008A dorsoventrally broad posterolateral process of the premaxilla and a postorbital process of the jugal that expands posterodorsally.
C. A. Boyd et al. 2009This species was diagnosed by Galton (1995) as follows: deep posterior process of premaxilla; extensive suturai contact between maxilla and nasal; small, oval antorbital fenestra; squamosal transversely wide; well-enamelled surface of cheek teeth has numerous low, rounded ridges. Further preparation and study of ROM 804 is currently underway by other authors (D. Evans pers. comm.) that will provide more information about the anatomy of this species.
