Six bryozoan species are described from the Lower Roadian (Guadalupian) of the eastern part of the East European Platform. The studied fauna is abundant and represented by various growth habits (branching, massive, encrusting, reticulate), developed in local bioherms. The studied bryozoan assemblage consists of trepostomes (three species), fenestrates (two species) and one cryptostome species with specific exozonal skeletons. Trepostomes of genus Dyscritella are dominant in this bryozoan association and possess acanthostyles differentiated by size. These structures probably performed protective and fixing functions. Fenestrate bryozoans have funnel-shaped and reticulate colonies with superstructure, which could have developed to protect against rapid sedimentation and predators. The identified bryozoan species are widely distributed within the East European Platform, with some similarities to the Roadian fauna of Transcaucasia, Guadalupian fauna of the Primorskij Kraj and Omolon massif.

俄罗斯萨马拉地区内姆达地平线（罗马尼亚）的二叠纪苔藓虫

从东欧平台东部的下部Roadian（瓜达鲁普ian）描述了6种苔藓虫。所研究的动物区系丰富，并以当地生物群落中形成的各种生长习性（分支，块状，结壳，网状）为代表。所研究的苔藓虫组合由三体（3种），孔雀类（2种）和一种具有特定外泌体骨骼的隐足类组成。Dyscritella属的Trepostomes在这种苔藓动物协会中占主导地位，并具有按大小区分的棘生动物样式。这些结构可能具有保护和固定功能。有孔的苔藓动物具有漏斗状和网状的菌落，具有上层建筑，这些菌落本来可以防止快速沉积和捕食者。识别出的苔藓动物物种广泛分布在东欧平台内，与Transcaucasia的Roadian动物区系，Primorskij Kraj的瓜达卢普动物群和Omolon地块有些相似。
