 In 1909 , the South @-@ African paleontologist Robert Broom visited the collection of the British Museum of Natural History . He concluded that Owen had mixed the partial distorted skull , teeth , and a mandible of a pareiasaur and a partial upper jaw of a dinosaur BMNH 47338 , which were actually from two different species . Broom kept the name Anthodon for the pareiasaur , but identified the other fossil as a member of the genus Palaeoscincus , naming the new species <unk> africanus in 1912 . He found that the anatomy of the teeth were quite different , even thought they resembled each other , as well as those of Stegosaurus . In 1929 , Baron Franz Nopcsa , unaware of Broom 's previous publication , provided a new name for Broom 's P. africanus , as <unk> Watson believed that the jaw should be differentiated from Anthodon . Nopcsa named the species Paranthodon <unk> , with the genus name derived from the Latin para , meaning " similar " , " near " , or " beside " , and Anthodon , and specific name honoring Owen . Due to present conventions , the specific name was later <unk> to owenii . In 1978 , Walter Coombs incorporated both names into the current nomenclature , Paranthodon africanus , as Paranthodon was the first new genus for the fossils and africanus was the first named species . This makes Palaeoscincus africanus and Paranthodon owenii junior synonyms of Paranthodon africanus .
