Notoceratops (meaning "southern horned face") is a dubious genus of extinct ornithischian dinosaur based on an incomplete, toothless left dentary (now lost) from the Late Cretaceous of Patagonia (in Argentina), probably dating to the Campanian or Maastrichtian. It was most likely a ceratopsian[1] and it was found in the Lago Colhué Huapi Formation.
