New data on Foraminifera (Polymorphinidae) of Western Siberia
Family Polymorphinidae Orbigny, 1846 is one of the important group of Polymorphinida Wedekind, 1937, orde Lagenata Maslakova, 1990 subclass Foraminifera Orbigny, 1826 class. The Polymorphinidae wall of shell is secreted calcareous and differ of their intrinsity construction. Morphological criterion has laid in the base to creation of different genera and species. In this paper anther have stadied the four species and one subspecies of the three genera. The morphological criteria are peculiarities of the Polymorphinidae text. They are based on different features elaborated mainly by the anther. In Polymorphininae Orbigny, 1846 subfamily the first time Pseudopolymorphina maxima Kseneva sp. nov. Globulina singularis Kseneva sp. nov. species and Globulina gracilis Cushman et Ozawa granudiscula Kseneva subsp. nov. subspecies are decrepitated. These Polymorphinidae have been found from the upper Campanian - Maastrichtian deposits of Gankinskaya suite the some name Horizon in Western Siberia. This suite consist of terrigenous deposits with including with calcareous materials. This paper have two paleontological tables with describing several taxons.
