Superfamily CALIGELLOIDEA Reitlinger in Rauzer-Chernousova & Fursenko, 1959

Description. See Fig. 2 .

Family BAITUGANELLIDAE Özkan & Vachard, 2015 Tests irregular, elongate or polygonal, generally lacking of the symmetries of the other foraminiferal groups. Proloculus inconspicuous or eventually absent, followed by irregular pseudochambers (without the architectural regularity of the modern foraminifera), separated by wall constrictions and pseudosepta randomly arranged. Wall brownish, microgranular to granular, thick to very thick, including (agglutinating?) clearer calcitic particles, unilayered, rarely bilayered, with an inner pseudofibrous, clearer layer. Apertures poorly characterized, generally difficult to distinguish of broken or dissolved parts of the wall. Eifelian–Serpukhovian.

Remark: Vulgarella Mikhno in Mikhno & Balakin, 1975 was originally described in the Parathuramminidae . It has never been re-described and is here tentatively included in the Baituganellidae because of its irregular and asymmetrical test, without openings or wellexpressed septa, but it could also be a more or less atypical bisphaerid.

Composition: Baituganella Lipina, 1955 ; Ademassa Vachard in Vachard et al., 1993; Halevikia Özkan & Vachard, 2015 ; Paracaligelloides Reitlinger in Chuvashov, 1965; Petchorina Reitlinger, 1962 ; Vulgarella Mikhno in Mikhno & Balakin, 1975.
