Diagnosis Test free, compressed, ovate in outline, planispirally enrolled and evolute, with a tendency to uncoil, later chambers extending back toward the proloculus at the inner margin, microspheric proloculus completely surrounded by enrolled chambers, whereas the megalospheric proloculus is not overlapped by the last. chambers of the early coiled portion; wall coarsely agglutinated on an organic lining that also covers the septa, imperforate, and lacking calcareous cement; aperture simple, rounded, terminal, at the dorsal angle of the final chamber, may be temporarily sealed by a plug of debris. L. Cretaceous (Neocomian) to Holocene; Atlantic; Pacific; North America; Europe; Africa. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details] Grammatical gender Ammotium is from the Greek "ammos" meaning sand and "otion" diminutive of "ous" meaning ear (Loeblich and Tappan 1953, p. 33, footnote). "Otion" (ὠτίον) is neuter in Greek therefore the genus is neuter.
ICZN Art. 30.1.2. a genus-group name that is or ends in a Greek word transliterated into Latin without other changes takes the gender given for that word in standard Greek dictionaries;
