The Ammodiscacea is a superfamily of Foraminifera in the order Textulariida. Tests (or shells) are made of agglutinated grains and consist of a proloculus (the initial chamber) followed by an enrolled tubular second chamber open at the distal end, that lacks internal septa but which may have growth constrictions.
Ammodiscacea includes a single family, the Ammodiscidae, which contains five subfamilies:
- Ammodiscinae
- Ammovertellininae
- Ammovolummininae
- Tolypammininae
- Usbekistaniinae
