Struthiomimus

Description

Struthiomimus est un genre éteint de dinosaures du clade des ornithomimosauriens et de la famille des ornithomimidés. Son nom signifie « semblable à l'autruche » car il présente une forte ressemblance avec une autruche.
Ses restes fossiles ont été découverts en Amérique du Nord, en particulier au Canada, en Alberta dans les formations géologiques de Dinosaur Park et de Horseshoe Canyon. Ces formations datent de la fin du Crétacé supérieur (Campanien et Maastrichtien).
Une seule espèce est rattachée au genre : Struthiomimus altus.
