Polycynodon is an extinctgenus oftherocephalians from theLate Permian ofSouth Africa. It is known from theCistecephalus Assemblage Zone.[1] The type species was first described asOctocynodon elegans by South African paleontologistRobert Broom in 1940, but the nameOctocynodon was preoccupied by a genus oflabrid fish first described in 1904.[2] Along withJohn T. Robinson, Broom instatedPolycynodon as a replacement name forO. elegans in 1948.Polycynodon is classified inBaurioidea, although its relationship to other baurioid therocephalians is uncertain.[3]
