The taxonomic diversity and distribution
of the Upper Ordovician bryozoans
of Mongolia are analyzed. Five heterochronous
assemblages of bryozoans are
established: Chigertei and Tsagaan del
in the Sandbian Stage and Bairim Ovoo,
Uuregnur, and Sairin in the Katian Stage.
The bryozoans are shown to be important
for solving complex problems of
stratigraphy of the Ordovician of Mongolia
and for paleogeographic reconstructions.

The structure of vesicular tissue in
bryozoans Esthoniopora lessnikowae
(Modzalevskaya, 1953) from the Latorp
Horizon (Lower Ordovician) of the Leningrad
Region is studied for the first
time. The intercolonial variability of this
species, which is expressed in the variations
in the thickness of the walls of
autozooecia, shape of apertures, and the
structure of vesicular tissue, is thoroughly
studied. New data are used to
supplement the description of the species
E. lessnikowae (Modzalevskaya,
1953) and the diagnosis of the genus
Esthoniopora Bassler, 1911.

Two new species of encrusting bryozoans
(Stenolaemata, Tubuliporida)
from the Middle Callovian (Middle Jurassic)
deposits of the Bryansk Region,
Oncousoecia guzhovi sp. nov. and Microeciella
fokinensis sp. nov., are described.
Their intracolonial variability,
which is due to differences in astogenetic
stages and to external factors, is
discussed.

A new family of the order Rhabdomesida,
Medvedkellidae fam. nov., is described.
This family consists of a new
genus, Medvedkella gen. nov., comprising
three species transferred from the
genus Rhombopora Meek, 1872: the
type species M. riasanensis (Schulga-
Nesterenko, 1955), M. diaphragmata
(Schulga-Nesterenko, 1955), and M.
