Tubothalamea

Alveolina is an extinct genus of foraminifera with an elliptical or spherical form.

Peneroplidae is a family of foraminifera in the superfamily Soritoidea.

The Spirillinida are an order of foraminifera in which the test, or shell, primitively consists of an enrolled open tube, coming after the proloculus, wound planospirally or conically, commonly composed of an optically single crystal of calcite. The aperture is a simple opening at the end of the tube. Advanced forms with more than one chamber may consist of a few crystals, or rarely, a mosaic of crystals of calcite.

The Miliolida are an order of foraminifera with calcareous, porcelacous tests that are imperforate and commonly have a pseudochitinous lining. Tests are composed of randomly oriented calcite needles that have a high proportion of magnesium along with organic material. Tests lack pores and generally have multiple chambers.

Quinqueloculina is a genus of foraminifera in the family Miliolidae.

Tubothalamea is a taxonomic class established for foraminiferans with tubular chambers. Includes the porcelaceous and agglutinated Miliolida and the monocrystalline and agglutinated Spirillinida. It is one of two classes of multichambered foraminifera based on SSU rDNA molecular studies with consideration of major morphological trends, the other being the Globothalamea.

Ammodiscidae is a family of foraminifera in the order Spirillinida. It was described by August Emanuel von Reuss in 1862. Ammodiscidae is the sole member of the monotypic superfamily Ammodiscoidea, which in turn is the sole member of the monotypic suborder Ammodiscina.

Miliolidae is a family in the superfamily Milioloidea of miliolid foraminifera.

Peneroplis is an extant genus of benthic Foraminifera in the family Peneroplidae. The genus is also represented in the fossil record.

Hauerinidae is a large and diverse family of miliolid forams (Loeblich & Tappan, 1988) that includes genera distributed among various subfamilies in the Treatise (Loelich &Tappan 1964) as well as genera named and described since.
