 Possible ceratopsians from the Southern Hemisphere include the Australian Serendipaceratops , known from an ulna , and Notoceratops from Argentina is known from a single toothless jaw ( which has been lost ) . Craspedodon from the Late Cretaceous ( Santonian ) of Belgium may also be a ceratopsian , specifically a neoceratopsian closer to ceratopsoidea than protoceratopsidae . Possible leptoceratopsid remains have also been described from the early Campanian of Sweden .
