Discorbacea

Discorbacea, Discorboidea in recent taxonomies, is a superfamily of foraminifera, (testate protists), with a range extending from the Middle Triassic to the present, characterized by chambers arranged in a low trochspiral; an umbilical or interiomarginal aperture, with or without supplementary apertures; and a wall structure that is optically radial.

Eight families are currently recognized, further characterized here in.

Discorbidae – Discorbacea in which each chamber is partly divided by an imperforate wall and the umbilical area partly is covered by chamber extensions. Discorbis, Neoeponides

Bagginidae – Discorbacea with an overall finely perforate test, but imperforate in a part of ventral side Baggina, Cancris

Eponididae – in which the aperture is interiomarginal and slitlike (or a narrow arch) or areal and cribrate. Eponides, Joanella, Paumotua, Poroeponides

Heleninidae – in which the primary aperture is interiomarginal and secondary apertures are sutural Helenina

MIsissippinidae – have distinct, translucent or opaque bands near the periphery on one or both sides; Mississippina, Stomatorbina
