The postcranial skeleton of the Triassic sphenodontid, Planocephalosaurus robinsonae, is described from dissociated remains recovered from the type locality at Cromhall Quarry, South Gloucestershire. A full reconstruction is outlined and its relationships within the Sphenodontidae are briefly discussed. A lower Jurassic eosuchian, Gephyrosaurus bridensis, is shown to share a number of characteristics with P. robinsonae, and Gephyrosaurus is consequently considered to be either a member of the Sphenodontidae or an offshoot from the stem Sphenodontidae.
