Magulodon

"Magulodon" is the name given to an as yet undescribed genus of dinosaur from the Early Cretaceous (Aptian to Albian stages, approximately 112 million years ago). It was a possible ornithischian, either an ornithopod or basal ceratopsian, which lived in what is now Maryland, in the United States. The type species, "Magulodon muirkirkensis", was coined by Kranz in 1996. It is a tooth taxon, based solely on a single tooth. Since it has not been formally described, it is also a nomen nudum. However, it was considered to be an indeterminate specimen in a paper which cited the intended type specimen but avoided using the name to prevent taxonomic clutter, so it would probably be regarded as a dubious name if it were to be formally published.
