New data on silurian stromatoporoids from the Bezymyanny creek (Chernov swell)

In the Bezymyanny Creek Silurjan section there are some problems of deposits dating, as far as clear lithological markers are not available and fauna complex is combined. Deposits are Wenlockjan dated based on brachiopod and coral fauna, conodont complex is Wenlockian and Llandoverian mixed. The paper presents results of Stromatoporoid complex researches that contain 11 species. One species is indicative for Wenlockjan, five for Ludlowjan and five are widely spread in Wenlockjan and Ludlowjan both. A rich stromatoporoid complex completes the faunistic characteristic of section and proves uneasy environment and importance continue dating research.
