Relation to Rhipaeosaurids[]
Rhipaeosaurus and Leptoropha were originally inside the Nycteroleteridae family, but now R. tricuspidens, R. talonophorus, and L. novojilovi, are in their own family: Rhipaeosauridae, a family of permian procolophonians parareptiles. This family was assigned to Cotylosauria by Tchudinov (1955), to Pareiasauria by Olson (1962), and to Pareiasauroidea by Carroll (1988).
Rhipaeosaurus tricuspidens.
