Foraminifera taxon details
From editor or global species database
Description All the representatives display the endothyroid coiling at least at the initial stage (eventually becoming uniseriate or biseriate) with supplementary deposits generally well developed. Wall dark simple, or with calcareous particles agglutinated (Paraendothyrinae) or microperforated with tectum (Omphalotinae). Aperture simple basal rarely areal or cribrate.
Occurrence. Late Tournaisian to middle (late?) Permian; cosmopolitan or only Tethyan–Uralian.
(Vachard and Le Coze (2022)).
The subfamilies and their composition is questionable and need to be reviewed.
(Vachard (2024) pers. comm.).

Diagnosis Test free, coiling planispiral to streptospiral, more or less involute, later may be uncoiled and rectilinear; wall microgranular, may be differentiated into more than one layer, may be alveolar, supplementary deposits present in advanced forms; aperture simple and basal to areal, cribrate in advanced forms, may have supplementary sutural apertures. U. Devonian (Fammenian) to U. Carboniferous. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
