Creation of new Foraminiferal system

N this paper are described the new conception of the system of foraminifera, which constitute an extensive and rather rapidly evolving group of organisms. This system is based, as the author supposes, on five criteria: morphological, ontophylogenetic, geo-chronological, paleogeographical and paleobiogeographical. The morphological criterion is a cardinal one, taking into account the creation chemical composition and microstructure of test walls. The rank of the established 15 subclasses of foraminifera assigned to the class Foraminifera d'Orbigny, 1826 was heightened, if compared with orders in the system known from the Basics of Paleontology (1959). Of great importance is the phylogeny of separate subclasses and establishing on this base 5 foraminifera development stages, corresponding to their morphological constitution and crucial tectonic moments during the Phanerozoic. In subclass Ammodisciata Podobina, 2014 two orders (Haplophragmiida Podobina, 2014; Lituolida Podobina, 2014) have been established on the base of studing of topo-types seperate genera and species. Early these genera were the base only for the one overfamilie Lituolidea Reuss, 1861. Then the genera of this overfamilie were difided and offered to two overfamilies which have been risen to orders [Podobina, 2014; 2015]. Separate taksons in principal genera took into account by auther from American classification [Loeblich, Tappan, 1964; 1987; 1988]. On the end of paper there are two paleontological tables with characteristic species of two orders - Haplophragmiida and Lituolida which differ by their morphological constraction and the other four criteria [Podobina, 2014; 2015].
