Barosaurus

Description

Barosaurus est un genre éteint de dinosaures herbivores sauropodes géants de la famille des diplodocidés. Ils ont vécu au Jurassique supérieur (Kimméridgien supérieur à Tithonien inférieur), soit il y a environ 152 Ma (millions d'années), en Amérique du Nord où il a été découvert dans la partie moyenne et supérieure de la formation de géologique de Morrison dans les états de l'ouest des États-Unis.
Plusieurs espèces ont été décrites comme appartenant au genre Barosaurus, mais une seule, Barosaurus lentus, décrite par Othniel Charles Marsh en 1890, est considérée comme valide,.
