Merkmale
Die Arten der Ordnung sezernieren ihre GehΓ€use aus Niedrig-Magnesium-Kalzit (< 5 mol-% Magnesium). Die GehΓ€use sind perforat, mehrkammerig mit hoch trochospiraler, drei-, zwei- oder uniserieller Anordnung der Kammern, die Wandung ist bilamellar. Bei vielen hΓΆher entwickelten Formen ist die Γffnung mit einer inneren Zahnplatte verschlieΓbar.
