Parathuramminacea comprises a superfamily within the foraminiferal order Fusulinida, characterized by tests (shells) that are unilocular, globular to elongate or irregular, or that may consist of a series or cluster of such chambers. Forms are either free or attached.[1]
Parathuramminacea is one of three superfamilies making up the Fusulinina in the Treatise on Invertebrate Paleontology Part C, 1964,[2] but as of 1988 (or prior to) expanded to thirteen.[1] Additional superfamilies being created out of the original three.
Parathuramminaceans were originally described [2] 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 , tubular or enrolled , and globular to tubular .
