Kritosaurus
Description
Source: Wikipédia
Kritosaurus est un genre éteint de dinosaures ornithopodes de la famille des Hadrosauridae. Il a vécu en Amérique du nord à la fin du Crétacé supérieur, Campanien et Maastrichtien, soit il y a environ entre 83,6 à 66,0 millions d'années (Ma).
Son histoire taxonomique est complexe, incorporant parfois les genres Gryposaurus, Anasazisaurus et Naashoibitosaurus. En 2014, il est incorporé à la nouvelle tribu des Kritosaurini. Cette tribu regrouperait aussi les autres genres nord-américains Naashoibitosaurus et Gryposaurus ainsi que les sud-américains Secernosaurus et Willinakaqe.
