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 ==References== * Alfred R.
