was one of only three superfamilies in the Fusulinina, the others being the Parathuramminacea and Fusulinacea. With the discovery of more genera since publication of the Treatise in 1964 and the concomitant development of new perspectives, the Endothyracea was split into a number of newly defined superfamilies, included in a revised and smaller Endothyracea based on the family Endothyridae.


Taxonomy

The Endothyracea, as now defined, envelops the Endothyridae and contains the following subfamilies. : Endostaffellinae : Endothyrinae : Endothyranoposinae
: Haplophragmellinae
