Nodosariacea is one of two superfamilies making up the foraminiferal order

Lagenida Lagenida is an order of benthic foraminiferal rhizaria in which the tests (shells) are monolamellar, with walls composed of optically and ultra-structurally radiate calcite, with the crystallographic c-axes perpendicular to the surface. Lagenids f ...

. The other being the Robuloidacea. Of these two Nodosariacea is the more advanced, as well as being the younger. Nodosariacea are characterized by planispirally coiled, uncoiled, or straight chambers, or which are coiled about a longitudinal axis. Test (or shell) walls are of finely perforate, radial laminated calcite. Apertures are peripheral or terminal, variable in form. Septa, dividing the chambers, are unilamellar, composed of a single layer, while the outer walls may be multilamellar, composed of multiple layers built up with the addition of new chambers.

'' included the Nodosariacea in the Rotaliina, with a range extending from the Permian to Recent, and divided it into three families, the Notodariidae, Polymorphinidae, and Glandulinidae. Loeblich and Tappan in 1988 removed Nodosariacea from Rotaliina and combined it with the newly established Robuloidacea to form the order Lagenina. The number of families was also increased within Nodosariacea to six with the addition of the Lagenidae, Ellipsolagenidae, and Vaginulinidae.
