 Paranthodon ( pə @-@ RAN @-@ thə @-@ don ) is a genus of extinct stegosaurian dinosaur that lived in South Africa during the Early Cretaceous , approximately 145 @.@ 5 – 136 @.@ 4 million years ago . Discovered in 1845 , it was one of the first stegosaurians found . Its only remains , a partial skull and isolated teeth , were found in the Kirkwood Formation . Although Owen initially identified the fragments as those of the pareiasaur Anthodon , after years of storage in the British Museum of Natural History , Broom identified the partial skull as belonging to a different genus , and named the specimen Palaeoscincus africanus . Several years later , Nopcsa , unaware of Broom 's new name , similarly concluded that it represented a new taxon , and named the binomial Paranthodon owenii . However , since the Nopcsa 's species name was assigned after Broom 's , and Broom did not assign a new genus , both names are now synonyms under the current naming , Paranthodon africanus . The genus name was chosen from the Ancient Greek para , " near " and Anthodon , for the originally proposed similarity of the specimens .
