Lucianosaurus is a genus of archosauriforme diapsid reptile known from the Late Triassic (Norian) of New Mexico. There is only one representative of this genus, L. wildi. Lucianosaurus possesses unknown affinities in the Archosauriformes, possibly being an archosaur or something different. Its remains first were diagnosed as a basal ornithischian dinosaur. Its uncertain classification is due to the lack of fossil remains attributable to this genus and species, for this taxon is known only from teeth.
