In the past, this gastropod was known as Bellerophon (Pharkidonotus). This is due to subgenera naming. In modern gastropod taxonomy, there are several sub and super names in use, including unranked groups that don’t fall into a classic hierarchy.
The family Bellerophontidae was named by McCoy in 1852 in the publication “Description of the British Paleozoic fossils in the Geological museum of the University of Cambridge”. The order Bellerophontida was named later by Ulrich & Scofield, 1897
