Taxonomic Remark Beedeina and Parabeedeina may refelect a possible vicariance between two different lineages. Beedeina clearly evoluted from Fusulinella when it is less evident about Parabeedeina. Either Parabeedeina derivates from a Tethys and Ural Ocean lineage either Beedeina migrated from North America to Ural ocean shelves, probably via Canadian Arctic and North Greenland, and/or across Panthalassa (North American Exotic Terranes and Japanese Terranes), to the Tethys shelves, and the two genera might be considered as synonyms.
Beedina is known to appear exactly at the base of the Desmoinesian of the U.S.A. (the base of which is probably located in the Podoskian Stage = early late Moscovian, of the Tethys and Ural oceans). In contrast, its disappearance is poorly known, but seems to be also located in the Desmoinesian, since, in our knowledge, Beedeina was never mentioned in the Missourian (U.S. regional equivalent of the Kasimovian = early late Pennsylvanian). Therefore Beedeina and Parabeedeina appear as being coeval in the late Moscovian (Podolskian+Myachkovian= Desmoinesian).

Diagnosis Original diagnosis: "ср. карбон, в. московский подъярус; Самарская лука, скв. 402, глубина 301-305 м. Р. средних размеров, веретеновидная или вытянуто-субромбоидная с округлой, реже угловатой срединной обл., прямыми или слабо прогнутыми боками, высота к. в двух последних об. постоянная или слабо возрастающая к осев. концам, обычно усеченным или округлым, реже р. удлиненная до субцилиндрической с широкими тупыми осев, концами, в нач. части р. или субсферическая и овоидная, или субромбоидная; число об. умеренное, обычно 6-7, у американских видов до 8, единично 9; ст.р. четырехслойная с четкой диафанотекой; септальная складчатость от слабой до довольно сильной, высокой и правильной, в сечении арочки чаще округлые, в септах нередки септальные поры; число септ в шести об. до 140 у евразийских форм и до 200 у американских; хоматы мощные, обычно до предпоследнего об., округлые или субквадратные в сечении, в нач. части иногда лентовидные до осев, концов; доп. отл. отсутствуют или слабо выражены, иногда развиты небольшие осев. уплотнения в средних об.; устье от узкого до умеренного. Ок. 20 видов. Ср. карбон, в. московский подъярус; Евр. часть России, Ср. Азия, Приморье, Испания, Гренландия, Китай, Япония, США, шир. Распр."

Middle Carboniferous, Upper Moscovian substage; Samara bend, borehole 402, depth 301-305 m. Medium sized test, spindle-shaped (fusiform) or elongated-subrhombic with a round, less often angular, median region, straight or slightly convex sides, the height of the chamber in the last two whorls is constant or slightly increasing toward the axial ends, usually truncated or rounded, less often the shell is elongate fusiform to subcylindrical with wide blunt extremities, or subspherical and ovoid, or subrhombic in the initial parts of the test; number of whorls moderate, usually 6-7, and in American species up to 8, rarely 9; the wall of the shell are four-layered with a clear diaphanotheca; septal folding weakly to fairly strong, high and regular; in section, the arches are more often rounded, septal pores are often found; number of septa in the sixth whorl up to 140 in Eurasian forms and up to 200 in American; chomata are strong, usually to the penultimate whorl, rounded or subquadratic in cross section, in the beginning part they are sometimes ribbon-shaped toward the axial ends; additional fillings are absent or weakly marked, sometimes not very developed axial fillings in the middle whorls; aperture from narrow to moderate. Around 20 species. Middle Carboniferous, Upper Moscovian substage; European part of Russia, Central Asia, Primorye, Spain, Greenland, China, Japan, USA, widely distributed.

Taxonomic Remark Beedeina and Parabeedeina may refelect a possible vicariance between two different lineages. Beedeina clearly evoluted from Fusulinella when it is less evident about Parabeedeina. Either Parabeedeina derivates from a Tethys and Ural Ocean lineage either Beedeina migrated from North America to Ural ocean shelves, probably via Canadian Arctic and North Greenland, and/or across Panthalassa (North American Exotic Terranes and Japanese Terranes), to the Tethys shelves, and the two genera might be considered as synonyms.
Beedina is known to appear exactly at the base of the Desmoinesian of the U.S.A. (the base of which is probably located in the Podoskian Stage = early late Moscovian, of the Tethys and Ural oceans). In contrast, its disappearance is poorly known, but seems to be also located in the Desmoinesian, since, in our knowledge, Beedeina was never mentioned in the Missourian (U.S. regional equivalent of the Kasimovian = early late Pennsylvanian). Therefore Beedeina and Parabeedeina appear as being coeval in the late Moscovian (Podolskian+Myachkovian= Desmoinesian).
