Original description Диагноз. Раковина крупная, спирально-плоскостная, эволютная, в поперечном сечении двояковогнутая или дисковидная. Внешняя поверхность сплошь покрыта мелкими бугорками, придающими раковине шероховатый вид. Раковина состоит из двух камер: начальной шаровидной и трубчатой, свернутои в правильную спираль, которая заканчивается открытым устьем. Стенка карбонатная, светлая, двухслойная, с неровными краями. Внутренний слой криптозернистый, внешний (развитый не повсеместно) микрозернистый. Диаметр раковины 1.0—1.2 мм.
(Igonin (1998)).
Diagnosis. The shell is large, planospiral, evolute, biconcave or discoidal in cross section. The outer surface is completely covered with small tubercles, giving the shell a rough appearance. The shell consists of two chambers: an initial spherical chamber and a tubular chamber, coiled into a regular spiral, which ends in an open aperture. The shell wall is calcareous, light-colored, two-layered, with jagged edges. The inner layer is cryptogranular, the outer (not developed everywhere) is microgranular. The shell diameter is 1.0-1.2 mm.
Occurrence: Permian, Ufimian, Pechora region.

Taxonomic remark A poorly known genus, very large and described as bilayered, Kozhimia Igonin, 1998, could be theoretically similar to Crassispirellina. However, this possible priority cannot be sustained for the following reasons. First, the two genera are of different ages: Kozhimia is Ufimian (early Middle Permian), whereas Crassispirellina is latest Permian in age. Second, the bilayered wall of Kozhimia is not precisely described nor visible on the unique illustration of Igonin (1998). Third, Kozhimia is only illustrated in equatorial section, and its perpendicular axial section remains hypothetically described in the text. Lastly, Kozhimia was never redescribed after its creation, which makes any further comparison purely hypothetical. In reality, Kozhimia seems to be more related to these large, late Early Permian and Middle Permian genera originally described as Hemigordius sensu Grozdilova, 1956, sensu Rauzer-Chernousova in Akopian (1974), and sensu Kobayashi (2002, figures 9.19, 9.20); secondly as Neodiscus sensu Ueno (1992); thirdly as Neohemigordius sp. sensu Kobayashi (1993, plate 1, figure 3); and fourthly as Uralogordius Gaillot and Vachard (2007) synonym of “Arenovidalina” sensu Baryshnikov et al. (1982) not Ho (1959). Furthermore, the holotype of Kozhimia has similarities with the transverse section of Hemigordius discoideus Reitlinger, 1950, illustrated by this author (plate 3, figure 14) from the Myachkovian (latest Moscovian) of Russia.
