文中简要介绍了中泥盆世Kayseria的时空分布及生态环境,对内蒙古西部珠斯楞海尔罕地区所含Kayseria的共生组合,与捷克、波兰等地进行了对比;指出本区中泥盆世生物地理区系隶属于旧世界领域。该组合属的分异度和丰度均较高,反映了平底浅海静水底栖组合2-3(Benthic Assemblage2-3)的特点。由于组合中的Kayseria的外形和内部构造较特殊(腹、背均具中槽,并有双重腕螺)、历时短,可作为特征属,故建议命名为Kayseria群落。最后描述了本区中泥盆统依克乌苏组上部Kayseria的两个新种:K.neimongolensis(sp.nov.)和K.lacrimiformis(sp.nov.)。
In this paper, the temporal and spatial distribution of the Middle Devonian Kayseria and its ecological environment are briefly introduced. The symbiotic combination of Kayseria and the Czech Republic and Poland is compared with that of the Kayseria contained in the Hanshoutan-Haerlan region of western Inner Mongolia. Geographical area under the old world. The genus of this genus is highly heterogeneous and abundant, reflecting the characteristics of Benthic Assemblage 2-3. Because Kayseria in the combination of the shape and internal structure of a more specific (abdominal, dorsal middling, and has a double brachiosaurus), lasted for a short time, can be used as a characteristic genus, it is proposed named Kayseria community. Finally, two new species of Kayseria from the Upper Cretaceous Ike Wusu Formation are described: K. neimongolensis (sp. Nov.) And K. lacrimiformis (sp. Nov.).
