The Fusulinina is a suborder of Foraminifera characterized by a test wall composed of tightly packed.  microgranular calicite, a few microns in diameter,  known from Ordovician to Triassic  marine sediments. Advanced forms may have walls divided into two or more layers.  Most are not spindle-shaped or fusiform, in spite of the name. That is reserved to the advanced Fusulinacea.

The Fusulinina is a suborder of Foraminifera characterized by a test wall composed of tightly packed.  microgranular calicite, a few microns in diameter,  known from Lower Silurian to Upper Permian marine sediments. Advanced forms may have walls divided into two or more layers.  Most are not spindle-shaped or fusiform, in spite of the name. That is reserved to the advanced Fusulinacea.  
By present reckoning the Fusulinina is diveded into 13 superfamiles.  Most were families from the earlier classification of Loeblich and Tappan, 1964, in the Treatise, that have been separated and redefined. The order given here is based on first known appearance

The Moravamminacea was originally part of the Parathuramminacea as the Moravamminidae and the Earladiacea part of the Moravaminnidae as the subfamily Earlandininae.  The Parathuramminacea now is what used to be the Parathuramminidae.
