GRYPOSAURUS NOTABILIS LAMBE, 1914

Revised diagnosis: Hadrosaurids of the genus Gryposaurus with the following unique combination of characters: sigmoidal lateroventral margin of the maxilla; large nasal arch located near the orbits and rising above the level of the frontals; narrow ‘U’-shaped posterior margin of the external naris; squamosal posterodorsal margin well above the level of the skull roof; infratemporal fenestra larger than the orbit; and rounded mandibular foramen. The skull of G. notabilis is generally more robust than that of G. latidens and G. incurvimanus , but less so than that of G. monumentensis .
