Today we know they are the most diverse group of shelled microorganisms in modern oceans. criterion to distinguish higher-level groups in Foraminifera (Pokorny, 1963; Loeblich and Tappan, 1964; Hohenegger and Piller, 1975). In the seminal work of Loeblich and Tappan (1988, 1989, 1992), Foraminifera were divided into 12 suborders that mainly differ by mineralogical and ultrastructural features of the test wall.
