描述产于贵州剑河八郎苗板坡剖面凯里组的艾苏贝一新种。新种腹壳壳喙细小尖凸,最高点位于壳喙处,两壳壳面具细圆且低小的放射线,放射线之间的间隔宽度与放射线的宽度相当,放射线上具有数量多、密度大、个体小的瘤点,为此建立新种瘤点艾苏贝(Nisusia granosasp.nov.)。凯里生物群中产有丰富的腕足动物化石,新种瘤点艾苏贝的发现增加了凯里生物群腕足类的分异度,为研究寒武纪腕足动物的辐射和多样性提供了重要的证据,也为研究艾苏贝类形态特征及钙质壳腕足动物壳面装饰在泥页岩中形态的变化和系统分类提供新的材料。
Describe a new species of Isupe, produced in the Carey Formation in Miaopingpo Section, Hom Island, Hom Province, Guizhou Province. The new species of beak shell with small sharp pointed, the highest point in the beak at the office, the shell of the shell with round and low radiation, radiation interval between the width of the width of radiation and radiation, there is a large number, density, Small individual tumor points, for which a new species of tumor site Nisusia granosasp.nov. The Kaili Biota is rich in Brachiopods fossils, and the discovery of a new species of nematocysts, Tesu Bay, increases the divergence of Brachiopods in the Kaili biota, providing important information for studying the radiation and diversity of Brachiopods Evidence, but also for the study of the morphological characteristics of the mussel shell and shell and shell of calcareous shell brachiopod shale morphological changes and systematic classification provide a new material.
