Description

Hypacrosaurus est un genre fossile de dinosaures ornithopodes de la famille des hadrosauridés et de la sous-famille des lambéosaurinés. Il comprend deux espèces, décrites à partir de fossiles datant du Crétacé supérieur, entre la partie supérieure du Campanien et le début du Maastrichtien, il y a environ entre 75 et 70 Ma,. Ses fossiles ont été retrouvés en Alberta, au Canada, ainsi que dans le Montana aux États-Unis.
