| 摘 要： | 对广西柳桥剖面、贵州晒瓦剖面和安徽平顶山西剖面晚二叠世末期硅泥质岩相地层中产出的介形类化石进行了系统分类学研究,共鉴定介形类化石30属86种,其中包括1个新属Denticupachydomella Yuan gen.nov.和2个新种Pseudobythocypris guiqianensis Yuan sp.nov.和Denticupachydomella spinosa Yuan sp.nov..该动物群主要由薄壳和个体较小的介形类组成,呈现出以古生代分子为主,同时含有少量典型中生代先驱分子(如:Abrobairdia,Lobobairdia)的混合动物群面貌.通过这些剖面之间的对比以及与前人研究资料对比,发现各剖面产出的介形类动物群具有强烈的地方性,三个剖面之间无相同分子,亦仅有20种曾报道于欧洲和东南亚等地区晚石炭世-晚二叠世地层.

| Abstract: | Taxonomy of ostracods yielded from the uppermost Permian siliceous and muddy rocks is studied in Liuqiao section.Guangxi,Shaiwa section,Guizhou and West Pingdingshan section,Anhui Province.Thirty genera and 86 sDecies were identified,including one new genus Denticupachydomella Yuan gen.nov.and Two new species Pseudo-bythocypris guiqianensis Yuan sp.nov.and Denticupachydomella spinosa Yuan sp.nov.The studied faunas,mainly composed of small and thin-shelled individuals,are dominated by typical Palaeozoic species accompanying with a few Mesozoic elements(e.g.Abrobairdia,Lobobairdia).A strong endemism is observed in the studied faunas.There is n0 common species between the three studied faunas,and only 20 species has been reported from the Upper Carboni- ferous-Upper Permian strata of Europe and Southeast Asia. |
