凯里生物群既是中国华南寒武系重要的布尔吉斯页岩型生物群之一,同时也是国内外已知少数微体布尔吉斯页岩型特异埋藏化石库之一,化石以二维的有机质壁形式保存。本文改进孢粉学处理方法,对来自中国贵州寒武系凯里组苗板坡、丹寨、竹坪和屯州等几个剖面以及相邻地层的共22个样品进行酸泡处理,获得微体化石新材料。结果显示,苗板坡剖面保存的化石多样性明显较高,其中发现的疑源类和丝状藻类最多,占统计总数(N=1549)的90%以上;同时还发现少量的后生动物残片,如威瓦西虫的骨板、腕足动物壳体残块以及蠕形动物表皮等,这些后生动物化石残片为研究某些后生动物的细微结构提供了重要补充信息,有助于对这些动物化石进行分类鉴定,并可能具有一定生物地层学意义。
The Kaili Biota is not only one of the important Burqish shale-type biota in the South China Cambrian, but also one of the known buried microfossil Burkith Shale type-specific burial fossils at home and abroad. Organic matter wall form preservation. In this paper, we improved the method of palynology, acid-treated the 22 samples from several sections of Miaobampo, Danzhai, Zhuping and Tuzhou, and other adjacent formations in the Cambrian of Cambrian of Guizhou Province in China. Body fossil new materials. The results showed that the fossil diversity preserved in Miaobailian section was obviously higher, of which, the highest number of suspected species and filamentous algae were found, accounting for more than 90% of the total number (N = 1549). A few epigenetic fragments were also found, Such as the bone of the wavidian worms, the remnants of brachiopods and the epidermis of the vermilion, etc. These metazoan fossil fragments provide important supplementary information for studying the fine structure of some metazoan species and help to fossil these animals Classification and identification, and may have some significance of biological stratigraphy.
