龙门山中段白石 -长河坝大型飞来峰泥盆纪地层发育 ,埃姆斯期划分为四个古生物群落。本文详细分析了养马坝组 Zdmir群落和 Xenospirifer fongi群落的生物组成、丰度、生活方式及生态环境。首次发现龙门山区以 Zdmir一属为主的生物群落受生态环境控制明显 ,可以出现在 Xenospirifer fongi群落之下 ,其时代属晚埃姆斯期 ,并建立了早泥盆世埃姆斯期群落的生态环境模式。
The Middle Longmenshan Baishi - Changhe dam flies over the Devonian strata, the Ames period is divided into four paleontological communities. In this paper, the biological composition, abundance, life style and ecological environment of Zdmir community and Xenospirifer fongi community in Yanmaba were analyzed in detail. For the first time, it was found that the community dominated by genus Zdmir in the Longmen Mountains was obviously controlled by the ecological environment and could occur under the community of Xenospirifer fongi, which belongs to the late Eames period and established the Early Devonian Ames Period Ecological environment model.
