ABSTRACT Crinoids and brachiopods are described from the Silurian Uzyan Formation of the Zilair Zone in the southern Urals. The occurrence of the graptolites Coronograptus praedeubeli suggests a late Homerian (Wenlock) age for the strata. A new disparid crinoid, Cicerocrinus gracilis Donovan sp. nov., is the oldest known member of this genus. It has a long, flexible and homeomorphic column, and a tall bryozoan palaeontology terminology (IBr2) (second primibrachial) axillary. All species of Cicerocrinus described previously have been limited to the Ludlow of the British Isles, Sweden and Estonia, and the Pridoli of Estonia. The poorly preserved brachiopod fauna is represented by small atrypid (Atrypa? sp.) and dalmanellid brachiopods (Levenea? sp.). The reported assemblage generally inhabited deep-water environments.

俄罗斯乌拉尔南部志留纪（文洛克）腕足类和海百合的新记录

摘要 乌拉尔南部 Zilair 区志留纪 Uzyan 组描述了海百合和腕足动物。笔石Coronograptus praedeubeli 的出现表明该地层为晚荷马时代（Wenlock）。一种新的异类海百合， Cicerocrinus gracilis Donovan sp。nov.，是该属已知最古老的成员。它有一个长的、灵活的和同形的柱子，以及一个高大的苔藓虫古生物学术语（IBr2）（第二原臂）腋窝。先前描述的所有 Cicerocrinus 物种仅限于不列颠群岛、瑞典和爱沙尼亚的 Ludlow，以及爱沙尼亚的 Pridoli。保存较差的腕足动物群以小型无尾足类（Atrypa? sp.）和dalmanellid 腕足类动物（Levenea? sp.）为代表。报告的组合通常居住在深水环境中。
