       Bradysaurus is a primitive genus of pareiasaur that gives an indication to how the pareiasaurs developed.‭ ‬The teeth of Bradysaurus have little in the way of cusps,‭ ‬and are also fairly high crowned.‭ ‬The scutes‭ (‬osteoderms‭) ‬in the skin are also not as well developed as those of later forms,‭ ‬which indicates that the pareiasaurs had a continuing and greater need for protection against the teeth of gorgonopsid predators.
       Apart from the more primitive features,‭ ‬Bradysaurus was still a fairly typical pareiasaur.‭ ‬The body was squat and heavily built,‭ ‬and was supported by four stout legs that sprawled out to the sides.‭ ‬The head was also equally heavily built with skulls being around forty-two to forty-eight centimetres long.‭ ‬The strong fairly large for the time body,‭ ‬strongly built skull and bones and osteoderm‭ ‬armour in the skin were the best defence against all but the largest predators of the time.
       Bradysaurus has in the past had many species assigned to the genus.‭ ‬Today,‭ ‬only the type species B.‭ ‬baini as well as B.‭ ‬seeleyi are considered to be valid.‭ ‬Key differences between these two species include B.‭ ‬seeleyi having‭ ‬between to twenty pairs whereas B.‭ ‬baini only has fifteen to sixteen pairs,‭ ‬and the jugals‭ (‬cheekbones‭) ‬of B.‭ ‬seeleyi are much larger and more robust than those of B.baini.‭ ‬Remains of B.‭ ‬baini are more common,‭ ‬than B.‭ ‬seeleyi.
