系统描述湖北宜昌和秭归新滩晚奥陶世庙坡组球接子类及多节类三叶虫动物群中的 14种 ,分属于 9属、7科。根据化石保存状态、挤压变形以及个体发育特征 ,对前人所报道的产于本组的有关三叶虫作了大量归并、转移和重新厘定。新的材料支持解释Telephinalongicephala的性双形现象。Atractopyge系首次在庙坡组中发现 ,以往它在三峡地区只见于临湘组。文中还将新疆的一个保留命名种Lonchodomascf.yohi重新命名为Lon chodomaszhangisp .nov .。
It systematically described 14 species belonging to 9 genera and 7 families in the ballot subclasses of the Late Ordovician Miaopo in Yichang and Xungui of Hubei Province and the multistage trilobite fauna. According to the state of preservation of fossils, extrusion deformation and individual development characteristics, a large number of trilobites reported in our predecessors have been merged, transferred and re-determined. New material supports interpretation of the sexual bisexuality of Telephinalongicephala. Atractopyge was first found in the Miapo Formation, where it was found only in the Linxiang Formation in the Three Gorges area. The article also renamed a retained name Lonchodomascf.yohi in Xinjiang as Lon chodomaszhangisp. Nov.
