摘    要:贵州遵义松林中南村黑沙坡下寒武统牛蹄塘生物群下部层位产有大型三叶虫,计有2属3种,1未定种:Zhenbaspis subconica S. G Zhang in Lu et al. , 1974, Z. longa Zhou in Lee et al. , 1975 ; Zhenbaspis sp. , Runnania similis Lee in Yin et Lee, , 1978, 确认 Zhenbaspis (Zhenxiongaspis) Lin et Yin in Yin et Lee, 1978,为 Zhenbastn‘sChang et Chu in Lu et al. ,1974的同义名。探讨Zhenbaspis的古地理分布及演化趋势。论文还描述与Zhenbaspis,Runnania共生的Tsunyidiscus及Mianxiandiscus,其中Mianxiandiscus产于下生物群即牛蹄塘组近底部,再次证实牛蹄塘下生物群的时代早于澄江生物群。

关 键 词:贵州  牛蹄塘组  下寒武统  牛蹄塘生物群  三叶虫  镇巴虫类

Abstract:The Niutitang Formation of Lower Cambrian located at Heishapo of Zhongnan Village, Songlin Town, Zunyi County, Guizhou, South China yields the Niutitang Biota(Zhao Yuanlong et al., 1999; Steiner et al., 2001). It was preserved in black mudstone of the Niutitang Formation. After weathering,the exposed black mudstones become white-gray shales or mudstones. The Niutitang Biota was composed of over 23 genera belonging to 7 phyla as well as some problematic taxa. Because these fossils occur in both upper and lower parts of the Niutitang Formation, the Biota was divided to Upper and Lower Biota(Zhao Yuanlong et al., 1999; Steiner et al., 2001; Yang Xinglian et al., 2000, 2003). The main groups of fossils are sponges and arthropods(Zhao Yuanlong et al., 2002). Trilobite is rich in specimens ,but very rare in species. Recently, some genera and species have been found at the middle and lower parts of the Niutitang Formation. The occurrence of theses taxa from the Niutitang Biota is quite significant. They not only provide new information about palaeogeographical distribution of trilobite, but also enrich the composition in the Niutitang Biota.
Keywords:Zhenbaspis    Lower Cambrian    Niutitang Biota    Niutitang Frmation    Guizhou
