Spirocyclinidae
Spirocyclinidae is a family of foraminifera included in the order Loftusiida. Tests are variably discoidal, aggulitinated with calcareous or microgranular cement. Interiors are complex with chambers partially subdivided. Walls and septa are pierced with ramifying and anastomosing channels. The family presently includes the following genera; ''Spirocyclina'', ''Anchispirocyclina'', ''Haurania'', ''Martiguesia'', ''Pseudospirocyclina'', ''Qataria'', ''Reissella'', ''Saudia'', ''Sornayina'', ''Spiraloconulus'', ''Streptocyclammina'', ''Timidonella'', and '' Vania''. Previous the subfamily Spyrocylininae according to Loeblich and Tappan, 1964 in the Treatise on Invertebrate Paleontology which then included ''Spriocyclina'', ''Anchispirocyclina'', ''Orbitammiina'', and ''Sornayina''.

Streptocyclammina
''Streptocyclammina'' is a genus of benthic forams with a flattened test from the Jurassic. The test (or shell) usually starts off streptospiral (coiled irregularly) hence the name, and becomes planispiral in the mature stage. Chambers are numerous per whorl, whorls become rapidly larger in peneropline fashion (as common in '' Pereroplis''). Sutures between whorls are slightly indented, the periphery rounded. The wall is finely agglutinated, externally imperorate, internally with massive septa perforated by numerous apertures. ''Streptocyclammina'' has been found in Jurassic sediments in Morocco, Italy, and the Balkans. ''Spiraloconulus'' and ''Timidonella ''Timidonella'' is a genus of large middle Jurassic forams, with microspheric tests up to in diameter.

Martiguesia
''Martiguesia'' is a genus of agglutinated benthic forams from the Upper Cretaceous (Santonian) of France. The test is free, the early stage planispirally coiled, becoming nearly straight during later growth. The agglutinated wall is externally imperforate, the interior with a coarse alveolar network. Chambers are subdivided and almost completely filled by irregular radial pillars. The aperture, cribrate. As a member of the Spirocyclinidae ''Martiguesia'' is related to ''Haurania'', ''Anchispirocyclina'', ''Streptocyclammina'', and of course ''Spirocyclina''. References * Alfred R.

Haurania
''Haurania'' is a genus of elongated, finely agglutinated benthic foraminifera included in the Spirocyclinidae. The test is free, starting with a brief planispiral coil followed by a straight uncoiled stage. The exterior is imperforate, the interior divided by radial septula or beams, perpendicular to the septa and outer wall. The aperture is cribrate, a series of openings on the terminal face. This genus is known from the lower and middle Jurassic of China, Iraq and Morocco. References * Alfred R. Loeblich, jr & Helen Tappan 1964. Sarcodina, Chiefly "Thecamoebians" and Foraminiferida.

Spiraloconulus
''Spiraloconulus'' is a genus of middle Jurassic forams with a coarsely agglutinated, microgranular, calcareous wall. The test is large, conical to cylindrical, coiled somewhat straight; the early coiled stage results in a flattened apex. Distinctly coiled microspheric tests are as much as 2 mm wide and 1.6 mm high. Megalospheric tests are smaller, up to 1.5 mm high and 1.1 mm wide. ''Spiraloconulus'' is known from the middle Jurassic of France, Italy, Sardinia, and Arabia.

Spirocyclina
''Spirocyclina'' is a genus of large forams, with a flat test as much as 10mm in diameter. Coiling is planispiral to slightly asymmetric and mostly involute, some becoming uncoiled with a straight final stage. The final whorl, or stage, has about 25 strongly arcuate chambers. Composition is of agglutinated matter, the outer layer of the wall imperforate. Chambers are subdivided into secondary chamberlets by internal structures. The aperture consists of a double row of pores on the apertural face. ''Anchispirocyclina'' and ''Martiguesia'' are among related genera. References * Alfred R. Loeblich, jr & Helen Tappan 1964.

Anchispirocyclina
''Anchispirocyclina'' is a genus of agglutinated discoidal forams known from the upper Jurassic (lower Kimmeridgian) to the lower Cretaceous (lower Valanginan) of Europe, north Africa, USA (North Carolina) and Cuba. The test of ''Anchispirocyclina'' is discoidal, thin and often slightly undulating. The early stage is close coiled, later flaring some becoming circular in outline. Walls are microgranular to finely agglutinated. Chambers have complex interiors produced by a network of rafters and beams. Those near the median plane have an irregular labyrinthic structure produced by radial pillars or buttresses extending from septum to septum between adjacent apertural openings.
