Carterinida is a small, recent, order of foraminiferans (in Kingdom Rhizaria[2][3]), once included in the Rotaliida as the superamily Carterinacea, named by Loeblich and Tappan in 1955.[4] Its present status as an order is based on the composition of the test (or shell) which is composed of large, fusiform, low-magnesium calcite spicules, commonly oriented parallel to the periphery, in a matrix of smaller spicules.[5] The tests themselves are trochospiral with later chambers that may be subdivided by secondary septa known as septula.

The Carterinida contains a single family, the Carterinidae with a single genus, Carterina named by Brady in 1884, based on Rotalia spiculotesta Carter, 1877. It is found in shallow water and is either attached or free.[4]
