Diagnosis
ReferenceDiagnosis
T. A. Gates and S. D. Sampson 2007Hadrosaurids 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.
T. A. Gates and S. D. Sampson 2007 (Gryposaurus incurvimanus)Hadrosaurids of the genus Gryposaurus possessing: dorsal premaxillary process that is more concave posteriorly than in other species of the genus; nasal arch smaller than in other species and positioned well anterior to the orbit and rising to a level below the frontals; jugal with a small spur on the posterior margin of the posteroventral flange; and slightly excavated ventral surface of the nasal hump. In addition, G. incurvimanus possesses the following unique combination of characters: nearly straight lateroventral margin of the maxilla; infratemporal fenestra larger than the orbit; and broad ‘U’-shaped posterior margin of the external naris. Gryposaurus incurvimanus is significantly more gracile than either G. notabilis or G. monumentensis. It has a smaller premaxillary lip than the other species, as well as premaxillae that are angled more steeply than in other species. Gryposaurus incurvimanus also possesses an anteroposteriorly shortened skull relative to the maximum skull depth.
A. Prieto-Marquez 2010Hadrosaurid dinosaur of the genus Gryposaurus characterized by the following autapomorphies: predentary denticles triangular and pointed, with bases that are wider or as wide as the denticles are tall; and infratemporal fenestra being both anteroposteriorly wider and dorsoventrally longer than the orbit. This species is also characterized by combining a nasal protuberance (that rises anterior to the orbits and above the level of the frontals) with a narrow U-shaped posterior margin of the narial fenestra, posterodorsal margin of the squamosal located well above the level of the skull roof, and rounded mandibular foramen (combination of characters modified from Gates and Sampson, 2007).
