The paper discusses a new conception of the foraminiferal system, which constitutes an extensive but rapidly developing group of organisms. In the author’s view, this system is based on five criteria those of morphological, ontophylogenetic, geochronological, paleogeographical, and paleobiogeo-graphical ones. The morphological criterion is a cardinal one with regard to the chemical composition and microstructure of test walls. The rank of the established 15 subclasses of foraminifera is assigned to the class Foraminifera d’Orbigny, 1826. Thus, the scientists generalized the data on the foraminiferal studies and raised this group of organisms from a rank to a class in comparison with orders in the system known from “Basics of Paleontology” [1]. The phylogeny of separate subclasses established on the basis of five foraminifera development stages is of great importance because it corresponds to the morphological structure and crucial tectonic movements during the Phanerozoic. The studies of the morphological peculiarities of the foraminiferal tests are based on the various methods elaborated mainly by the author.
