Gorgosaurus

Lambe 1914

Le gorgosaure, Gorgosaurus, est un genre fossile de dinosaures théropodes tyrannosauridés de la sous-famille des Albertosaurinae. Il vivait dans l'ouest de l'Amérique du Nord vers la fin du Crétacé supérieur, au Campanien, il y a entre 76,5 et 75 Ma avant notre ère. Des restes fossiles ont été trouvés dans la province canadienne de l'Alberta et aussi dans l'État américain du Montana. Les paléontologues ne reconnaissent que l'espèce type, Gorgosaurus libratus, bien que d'autres espèces aient été classées à tort dans ce genre.
