文中通过对Ushbaspis hubeiensis(Lin,1978)新材料的研究,对该种三叶虫躯体构造特征做了重要补充,使人们对它有更全面的认识,也将为今后进一步对乌什巴盾壳虫类(ushbaspid)三叶虫的分类、系统演化的研究以及对寒武纪第二世生物地层划分,提供一些重要依据。文中还就张文堂等(1980)将采自贵州湄潭的Kepingaspis sp.标本鉴定为Metaredlichioides constrictus Qian and Yao,1974提出质疑。
Through the research on the new material of Ushbaspis hubeiensis (Lin, 1978), this article makes an important supplement to the somatic structure feature of this kind of trilobite and makes people have a more comprehensive understanding of it. It will also further study the characteristics of Ushbaspis hubeiensis (Ushbaspid) trilobite classification, phylogeny and the Cambrian second biological strata, provide some important basis. The paper also Zhang Wen Tang et al (1980) will be collected from Meitan, Guizhou Kepingaspis sp. Specimens identified as Metaredlichioides constrictus Qian and Yao, questioned.
