A new genus of the Arenigian bryozoans, Lynnopora, and its systematic position in the family Revalotrypidae Gorjunova, 1988

A new genus Lynnopora gen. nov. with the type species L. lunata sp. nov. and a new species Revalotrypa krestensis Koromyslova sp. nov. from the Arenigian Stage (Latorp and Volkhov horizons) of the Ordovician of the Leningrad Region are described. The positions of the genus Revalotrypa Bassler, 1952 and the family Revalotrypidae Gorjunova, 1988 in the order Cystoporida are substantiated. The problems of biogeography and ecological adaptations of bryozoans of the family Revalotrypidae are discussed.
