| 摘 要： | 贵州剑河八郎松山寒武系黔东统都匀阶“清虚洞组”灰岩、泥岩中产大量三叶虫及带软躯体动物多门类化石.其中三叶虫非常丰富,包括莱德利基虫类、耸棒头虫类、褶颊虫类等.本文描述的褶颊虫类八郎村虫Balangcunaspis （Yuan et Zhao,1997）包括横宽八郎村虫Balangcuna-spis（B.）transversus及次柱形八郎村虫（相似种）Balangcunaspis（B.） cf. subcylindricus,其中横宽八郎村虫也见于凯里组下部层位.八郎村虫的发现,使其产出层位下延,丰富了“清虚洞组”三叶虫的组合,也为寒武系第4阶的研究提供了新的三叶虫材料和依据. |

| Abstract: | Abundant fossils of Trilobites and soft-bodied animals have been found in mudstone and limestone of ＂ Tsinghsutung Formation＂ in Songshan Section （Dunyunian Stage, Qiandongian series, Cambrian） of Balang district, Jianhe County, Guizhou Province. ＂ Tsinghsutung Formation＂ is rich in trilobites, including Redlicbiida, Corynexochida and Ptychopariida. Balangcunaspis trilobites described here contain two species： （ B. ） trasversus Balangcunaspis and Balangcunaspis （ B. ） cf. subcylindricus, and the Balangcunaspis （ B. ） trasversus had ever been reported from lower Kaili Formation. The discovery of the Balangcunaspis indicates not only has the appearance layer extended downwards, but also the combination of Trilobite in ＂Tsinghsutung Formation＂ has became more affluent. Besides, it provides some material and evidence in study of the 4^th Stage of Cambrian. |
