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
T. A. Gates et al. 2011Hadrosaurine hadrosaurids that possess a diastema approximately one third the length of the tooth row; long anteromedial maxillary process seen through external nares and not associated with premaxillary downturning; anterior process of jugal dorsoventrally symmetrical; posteroventral jugal flange long and narrow, distinctly set off from jugal body more prominently than in Gryposaurus or Kritosaurus; alar process larger and more highly angled than in other hadrosaurine species; deeply developed basipterygoid ridge that extends ventrally between and to the ventral level of the basipterygoid processes; a short, mediolaterally narrow median process on the basipterygoid ridge that is much smaller than in all other hadrosaurine taxa.
