Coelophysis

Description

Coelophysis est un genre éteint de dinosaures, de la famille des Coelophysidae. L'espèce Coelophysis bauri figure parmi les premiers dinosaures découverts, en 1881. Le nom Coelophysis signifie « forme creuse ».
Ce sont des théropodes de taille moyenne, des bipèdes carnivores. Ils ont vécu à la fin du Trias supérieur et au début du Jurassique inférieur, il y a environ entre 216 et 196 Ma (millions d'années). Leurs fossiles ont été découverts dans plusieurs États des États-Unis (Nouveau-Mexique, Arizona, Connecticut, etc.), et dans le sud de l’Afrique (Zimbabwe, Afrique du Sud).
