描述青海化隆拉脊山地区寒武纪武陵世至芙蓉世多节类三叶虫34个种,分属于33个属和17个科。其中包含4个新种,即:Paranomocarella dingmaoshanensis sp.nov.,Adelogonus oblongus sp.nov.,Placosema qinghaiense sp.nov.和Meteoraspis qinghaiensis sp.nov.。对有关的属、种及其归类做讨论和修订,研究表明该地区寒武纪武陵世至芙蓉世多节类三叶虫有较高的分异度,为进一步研究祁连山地层区寒武系地层的划分和对比、沉积相分析和生物地理区的划分等,提供重要的古生物依据。
Describe 34 species of the multinomial trilobites in the Wulings to Fleur seasons of the Cambrian in the Longhua area, Huilong area, Qinghai Province, belonging to 33 genera and 17 families. There are four new species, Paranomocarella dingmaoshanensis sp. Nov., Adelogonus oblongus sp. Nov., Placosema qinghaiense sp. Nov. And Meteoraspis qinghaiensis sp. Nov. The related genera, species and their classification are discussed and revised. Studies have shown that there is a high degree of differentiation between the Cambrian Wulings and Furong Sectarous Clover in the area. In order to further study the Cambrian Stratigraphic division and contrast, sedimentary facies analysis and the division of biogeographic areas, provide important paleontological basis.
