Parathuramminaceans were originally described as Fusulinida that consist of a single globular or tubular chamber, or cluster of such chambers. Test wall simple, consisting of calcareous granules in calcareous cement. At that time it was divided into the globular Parathuraminidae, tubular or enrolled Caligellidae, and globular to tubular Moravamminidae.
