本文系统介绍了湖北宜昌黄花场及浙江常山黄泥塘剖面Arenig统几了虫分布发育规律,指出华南地区Arenig统的几丁虫自下而上可划分为:Conochitina symmetrica,Eremochiti-na baculata, Eremochitina brevis-Conochitina, pirum, Rhabdochitina turgida等生物带.讨论了华南地区这一时期几丁虫的古生物地理特征,认为华南地区在Arenig世早期与北冈瓦纳大区同期几丁虫面貌相似;中晚期则与其它古生物门类一样,更相似于波罗的海板块同期几丁虫组合面貌。
This paper systematically introduced the development patterns of the Arenigian distribution in the Huanghuachang, Yichang, Hubei Province, and the Huangnitang Section in Changshan, Zhejiang Province. It was pointed out that the chitin in the Arenig system in South China can be divided into Conochitina symmetrica, Eremochiti-na baculata and Eremochitina brevis -Conochitina, Pirum, Rhabdochitina turgida, etc. The paleontological features of the chitin in South China during this period were discussed, and the similarities were observed in the early Arenigian Period between South Guinea and Gujranwala Like other palaeontology clades, it is more similar to the same chitin assemblage in the Baltic Sea plate.
