The Endothyracea is a superfamily in the foraminiferal order, Fusulinida (or as often, suborder Fusulinina) known from the upper Devonian to the Lower Permian. Probably ancestral to the Fusulinacea.[1][2]
Diagnosis
Fusulinida with multichambered, septate tests, planispirally to streptospirally coiled at least in the early stage, may uncoil and become straight in the late growth stage.[1]
Taxonomy
Taxonomic relationships
The Endothyracea as presented in the Treatise[2] 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 concomitant development of new perspectives, the Endothyracea was split into a number of newly defined superfamilies, included in a revised and smaller Endothyracea [1] based on the family Endothyridae.
Taxonomy
The Endothyracea, as now defined, envelops the Endothyridae[1] and contains the following subfamilies.
