Stegosaurus

Marsh 1877

Étymologie Reptile à toit.

Le stégosaure, nom vernaculaire du genre fossile Stegosaurus, désigne des dinosaures herbivores caractérisés par de grandes plaques osseuses alternées en deux rangées sur leur dos, de formes et tailles différentes selon les espèces. Ils ont vécu durant le Jurassique supérieur, il y a environ entre 155 et 145 Ma sur le continent appelé Laurasie, des États-Unis jusqu'au Portugal et au Maroc actuels. Le plus ancien stégosaure trouvé provient de la région de Boulahfa au Moyen Atlas marocain, en Afrique du Nord.
