Acarinina acarinata, from here.

Belongs within: Rotaliida.
Contains: Globorotalia.

The Globorotaliidae are a group of trochospiral, planktonic Foraminifera known from the Palaeocene to the present. In most genera, forming the subfamily Globorotaliinae, the test has a primary aperture only on the umbilical side. In the Lower to Middle Eocene genus Truncorotaloides, secondary sutural apertures are present on the spiral side in addition to the primary umbilical aperture (Loeblich & Tappan 1964).

Characters (from Loeblich & Tappan 1964): Test trochospiral; chambers ovate, spherical or angular; primary aperture interiomarginal, extraumbilical-umbilical, secondary sutural apertures may occur on spiral side.
