Abstract

The ostracod assemblages of the Baksian and Dolborian horizons of the Chunya River basin (a right tributary of the Podkamennaya Tunguska River) have been studied. They add essentially the paleontological characteristics of Upper Ordovician deposits of the Siberian Platform. The age of deposits was verified and the studied sections were correlated with the Gaindinskaya 3 reference borehole. Two new genera and 9 new species were described. Images for known ostracod species are given.

摘要

研究了春亚河流域（波德卡门纳亚通古斯卡河的右支流）的巴克希斯人和多尔伯里亚人视界中的兽类组合。它们实质上增加了西伯利亚平台上奥陶纪沉积的古生物学特征。验证了矿床的年龄，并将研究的断层与Gaindinskaya 3参考钻孔相关联。描述了两个新属和9个新种。给出了已知兽脚类物种的图像。
