       Paranthodon remains were first described when they were incorrectly included with the remains of a parieasaur named Anthodon.‭ ‬The inclusion of these remains also gave the incorrect identification for Anthodon as a dinosaur instead of a parieasaur until‭ ‬1912‭ ‬when Robert Broom separated an upper jaw from the genus.‭ ‬While Broom correctly identified the jaw as that of a dinosaur and not a parieasaur,‭ ‬he placed it within an existing‭ ‘‬wastebasket‭’ ‬genus of Palaeoscincus,‭ ‬as P.‭ ‬africanus.‭ ‬In‭ ‬1929‭ ‬Franz Nopcsa studied the specimen,‭ ‬and unaware that Robert Broom has already classified it as that of a dinosaur,‭ ‬created a new genus and type species,‭ ‬Paranthodon owenii.‭ ‬In‭ ‬1978,‭ ‬another palaeontologist named Walter Coombs altered owenii to oweni which is the correct grammar,‭ ‬and since this time this has been the standard named type species reference for this genus.‭ ‬It should be pointed out at this point that Paleoscincus is widely considered to be a dubious dinosaur genus because it was first named by a description of only the teeth.
       Although Franz Nopsca made the correct identification of Paranthodon as a stegosaur,‭ ‬many others instead interpreted the partial remains of this genus as those of an ankylosaur,‭ ‬another armoured but quite different type of dinosaur.‭ ‬It would not be until‭ ‬1981‭ ‬when another palaeontologists named Peter Galton actually demonstrated that Paranthodon was indeed a stegosaur and not an ankylosaur.
       As you may expect,‭ ‬Paranthodon would have been a quadrupedal low browsing dinosaur,‭ ‬that had plates and possibly spines running along its back.‭ ‬However since these have so far not been discovered,‭ ‬it is impossible to be certain to their arrangement.‭ ‬A‭ ‬2008‭ ‬report by Maidment et al places Paranthodon as closely related to Loricatosaurus,‭ ‬Tuojiangosaurus and Stegosaurus.
