Cibicides

Many, including: Cibicides is a genus of cosmopolitan benthic foraminifera known from at least as far back as the Paleocene (Loeblich & Tappan, 1988) that extends down to the present.

The test, or shell, of Cibicides, which is commonly found attached, is multichambered, plano-convex, trochospiral, with a flat or dished-out evolute spiral side and a strongly arched, involute umbilical side.

The test wall is calcareous, perforate, bilamellar, with a radial microstructure.

Cibicides, named by Montfort, 1808, is included in the subfamily Cibicidinae, family Cibicididae, superfamily Planorbulinacea; suborder Rotaliina in Loeblich and Tappan, 1987 and order Rotaliida in Loeblack and Tappan, 1992.

It was put, instead, in the Orbitoidacea in Loeblcih and Tappan, 1964, in the Treatise Part C, and in the Anomalinidae in Cushman, 1950.
