Thescelosaurinae

Sternberg 1940

Thescelosaurus est un genre fossile de petits dinosaures herbivores du sous-ordre des Ornithopodes qui a vécu à la fin du Crétacé en Amérique du Nord. Cet ornithischien faisait partie de la dernière faune dinosaurienne avant l'extinction du Crétacé-Tertiaire (K-T) il y a environ 66 millions d'années. L'espèce type et première espèce définie est Thescelosaurus neglectus.
