Lucianosaurus
Lucianosaurus is an extinct genus of amniote of unknown affinities, known only from teeth. Initially described as a basal ornithischian dinosaur, subsequently reclassified as a member of the clade Archosauriformes of uncertain phylogenetic placement and later, taking into account the similarity of its teeth to the teeth of traversodontid cynodonts such as Dadadon, as an amniote of uncertain affinities.
Fossil remains of Lucianosaurus were first found in the Late Triassic Dockum Group of Eastern New Mexico, United States. The generic name refers to Luciano Mesa in Guadalupe [County, New Mexico|Guadalupe] and Quay counties of New Mexico where the teeth of Lucianosaurus were first uncovered and identified.
