Nanosaurus

Description
Source: Wikipédia
Nanosaurus (« petit lézard » ou « lézard nain ») est le nom donné à un genre de dinosaure néornithischien qui vivait il y a environ 155 à 148 millions d'années, au cours du Jurassique supérieur. Ses fossiles sont connus de la Formation de Morrison dans le sud-ouest des États-Unis. Le type et la seule espèce, Nanosaurus agilis,, a été décrit et nommé par Othniel Charles Marsh en 1877. Le taxon a une histoire taxonomique compliquée, en grande partie par le travail de Marsh et Peter M. Galton, impliquant les genres Laosaurus, Hallopus, Drinker, Othnielia et Othnielosaurus, les trois derniers étant maintenant considérés comme des synonymes de Nanosaurus,. Quoique Othnielosaurus consors reste accepté par d'autres,. Il avait historiquement été classé comme un Hypsilophodontidae ou Fabrosauridae , types de petits herbivores bipèdes, mais des recherches plus récentes ont abandonné ces groupements considérés comme paraphylétiques et Nanosaurus est aujourd'hui considéré comme un membre basal des Neornithischia.
