Аннотация:In the period from 1985 to 1993 B.B. Nazarov and A. Ormiston described
from the Upper Carboniferous and Lower Permian sediments of the Southern Urals
a number of species of radiolarians with unusual polyhedral skeletal shape, assigned
to the genus Polyentactinia Foreman, 1963. However, in 1989, H. Kozur and H. Mostler
from the Sakmarian Stage described a new genus Polyedroentactinia with the type
species P. cisuralica Kozur et Mostler, 1989. The general plan of the skeleton structure
of this genus coincides with that of species of Nazarov and Ormiston. In recent years,
several articles have been published on the revision of the genus Polyentactinia,
according to which a number of its species were transferred to the genus
Polyedroentactinia.
