Gryposaurus

Description

Gryposaurus est un genre éteint de dinosaure ornithopode de la famille des hadrosauridés et de la sous-famille des saurolophinés. Il a vécu en Amérique du nord à la fin du Crétacé supérieur, au Campanien et Maastrichtien, soit il y a environ entre 83,6 à 66,0 millions d'années. Les quatre espèces identifiées ont été retrouvées au Canada (Alberta) et aux États-Unis (Montana, Utah, Texas).
Son histoire taxonomique est complexe. Sa grande similitude avec le genre Kritosaurus, signalée l'année même de sa découverte en 1914 a conduit pendant tout le XXe siècle à un va-et-vient permanent entre des études qui regroupaient les deux genres sous le seul nom antérieur de Kritosaurus, et d'autres qui distinguaient les deux. Ce n'est que depuis les années 1990 que les deux genres sont considérés comme valides.
