根据近来的发现 ,区域地层的阐明及生物在寒武系与前寒武系界线上下的变化 ,澄江早寒武世地层划分作了修订。早寒武世岩石地层名称的更换 ,年代地层及生物地层单位的分带这里作了简述。目前的岩石地层单位从下到上是渔户村组 (梅树阶 ) ,黑林铺组 (筇竹寺阶 ) ,红井哨组、乌龙箐组 (沧浪铺阶 )及山邑村组 (龙王庙阶 )。此层序可分为 12个组合带及 2个亚带。所有的组合带在中国西南地台区都有存在 ,但两个亚带在澄江是区域性的。云南东部震旦系与寒武系的界线暂时置于渔户村组小歪头山段的底界 ,位于小壳化石最早出现的下部。中国的Parabadiella ,摩洛哥的Abadiella及澳大利亚的Abadiellahuoi这里重新作了研究。Parabadiella及Abadiella是两个不同的属。模式标本的图片在这里再次刊出。澳大利亚的Abadiellahuoi一种应是Wutingaspis的一个新种 (WutingaspisjelliChangsp .nov .)。¨Opik( 1975 )的Dolerolenus( ?)sp .nov .一种应归属Parabadiellahuoi一种。Parabadiella是中国也是澳大利亚寒武系最古老的三叶虫。澳大利亚的Wutingaspisjelli的层位与摩洛哥Abadiella的层位相当 ,可与中国的Wutingaspis Eoredlichia带的上部对比。
Based on the recent discoveries, the clarification of regional stratigraphy and the change of biota between the Cambrian and Precambrian boundaries, the stratigraphy division of the Chengjiang Precambrian was revised. The replacement of the names of the Early Cambrian lithostratigraphy, the stratification of the Chronostratigraphy and the biostratigraphic units are briefly described here. The current lithostratigraphic units from bottom to top are the Fishermen’s Village Group (Meishujian), Heilinpu Formation (Qiongzhusi), Hongjinggou Formation, Wulongwan Formation (Canglangpu) and Shanyi Village Group (Dragon King temple). This sequence is divided into 12 combined bands and 2 sub-bands. All the combination zones exist in the southwestern Taiwan area, but the two sub-zones are regional in Chengjiang. The boundary between the Sinian and Cambrian lines in the eastern part of Yunnan was temporarily placed at the bottom of the Xiaowutou section of the Fudou Village and was located at the earliest lower part of the small shell fossils. Parabadiella in China, Abadiella in Morocco and Abadiellahuoi in Australia reopen here. Parabadiella and Abadiella are two different genera. The pictures of the model specimens are listed here again. A species of Abadiellahuoi in Australia should be a new species of Wutingaspis (Wutingaspisjelli Chhangsp .nov.). ¨Opik (1975) Dolerolenus (?) Sp. Nov. A species that belongs to Parabadiellahuoi. Parabadiella is the oldest trilobite in China and also in the Cambrian of Australia. The Wutingaspisjelli level in Australia is comparable to that of Abadiella in Morocco, comparable to the upper part of the Wutingaspis Eoredlichia belt in China.
