       Eriphostoma is a little known genus of gorgonopsid,‭ ‬but one that is important to the study of them given that Eriphostoma may well represent the earliest known gorgonopsid.‭ ‬There has been speculation that another genus called Broomisaurus and known only from fragmentary fossils may be junior synonym to Eriphostoma.
