本文详细研究了贵州盘县滑石板村滑石板阶层型剖面的类动物群 ,有 5属 2 6种及亚种 ,其中 1未定种。滑石板阶包含 2个带 ;Pseudostaffella antiqua- P.antiqua posterior带及 Pseudostaffella composita- P.paracom-pressa带。滑石板阶底界以化石 Eostaffellina protvae- Pseudostaffella antiqua演化系列中 Pseudostaffella anti-qua首次出现为标志 ,具体位置在层型剖面的层 1,层型点置于层 1之底 AAK5 6点上 ;顶界止于化石 Profusu-linella priscoidea带之底。滑石板阶的 Pseudostaffella antiqua- P.antiqua posterior带可以和俄罗斯下巴什基尔阶Severoketmensky层的 Pseudostaffella antiqua带对比 ;滑石板阶的 Pseudostaffella composita- P.paracompressa带大致与俄罗斯下巴什基尔阶 Prikamsky层的 Pseudostaffella praegorski- Profusulinella staffellaeformis带的一部分对比。滑石板阶大致相当于国际地层表中的巴什基尔阶 (Bashkirian)中部
In this paper, we have studied in detail the fauna of talc-type stratigraphic section of the talus village in Panxian County, Guizhou Province. There are 5 genera, 26 species and subspecies, of which 1 is undetermined species. The talc level contains two bands; the Pseudostaffella antiqua-P. antiqua posterior band and the Pseudostaffella composita-P. pararacom-pressa band. The bottom boundary of talc plate is marked by the first appearance of Pseudostaffella anti-qua in the evolution series of fossil Eostaffellina protvae-Pseudostaffella antiqua. The specific position is at layer 1 of the stratotype profile and the stratotype point is placed at the bottom of layer 1 at AAK5. Limits to the bottom of the fossil Profusu-linella priscoidea zone. The Pseudostaffella antiqua-P. antiqua posterior band of the talcum plate can be compared with the Pseudostaffella antiqua belt of the Severoketmensky layer of Russia’s Lower Siskering Order; the Pseudostaffella composita- P. paracompressa band of the talcum plate is roughly similar to the Pseudostaffella antiqua belt of the Russian Federation’s Prikamsky layer Pseudostaffella praegorski-Profusulinella staffellaeformis with a part of the contrast. The talc level roughly corresponds to the central Bashkirian in the international stratigraphic table
