摘要
我国有关早寒武世中期以后的单板类报道和研究较少。本文描述和讨论产于贵州省台江县八郎村下寒武统顶部和中寒武统下部的一些单板类化石,计有Helcionella terraustralis,Coreospiracf.rugosa,Latouchella taijiangensis sp.nov.,Latouchella sp.,Monoplacophora gen.et sp.indet.等。这些单板类化石的发现不仅丰富了“凯里动物群”的内容,为该区中、下寒武统的划分提供了单板类的证据,而且对研究单板类的演化和地理分布规律增加了重要材料。
The Cambrian monoplacophorans described in this paper were collected from Taijiang,Guizhou. Among them, Helcionella terraustralis, Coreospira cf. rugosa and Monoplacophoragen. et sp. indet. from the top of the Qingxidong Formation are associated with Chittidillasp.,Protocephalus sp., Redlichia cf. takooensis and Bathynotus kueichouensis,indicating latestEarly Cambrian in age. The other two species from the middle and upper parts of the Kaili Formation, Latouchella taijiangensis sp. nov. and Latouchella sp., may corrcspond to MiddleCambrian in age (the Oryctocephalus--Xingrenaspis Zone).
