Asterigerinacea are characterized by a trochospiral or nearly planispiral arrangement of the chambers, which are fully or partially subdivided by internal partitions. The primary aperture is commonly on the interior margin and secondary apertures are commonly along the sutures. Apertures may also form on the chamber surfaces as well. Test walls are composed of optically radial calcite. The Asterigerinacea range from the Cretaceous to Recent, the oldest family being the Asterigerinidae.
