Description Test small subglobose−ovoid to ovoid−fusiform, with two, to three and a half volutions. The initial volution always coiled at large angle in respect to the following volutions. The initial chamber is relatively large with outside diameter 30–70 μm. The proloculus/test ratio is 1:4 to 1:6 as opposed to 1:10 to 1:30 in Schubertella. Volutions coiled loosely, except for the first one that is tight. Chomata are very small to nearly undetectable. Septa are straight throughout.Wall is thin, often poorly differentiated. In well preserved specimens it is two−layered protheca with a thin, dark tectum and thicker, light lower layer (tectorium). A discontinuous upper tectorium observed in some specimens.
Stratigraphic and geographic range.—Schubertina similarly to Schubertella is distributed globally within the tropics−subtropics. It has been documented in the upper lower Bashkirian, Askynbashian Horizon in the Urals (Sinitsyna and Sinitsyn 1987), Donets Basin (Manukalova−Grebenyuk et al. 1969) and Timan−Pechora (Nikolaev 2005) and in early Atokan (late Bashkirian) in North America (Groves 1986, 1991). The upper range of Schubertina is not clear at the moment. Some forms that can be considered as Schubertina are reported from Wordian (early Midian), Capitanian (late Wordian) and Lopingian (Skinner and Wilde 1966; Leven 1998a).
