The Ordovician Dawan Formation of Yichang has been studied for a long time,but the graptolite succession of the formation is still poorly known,particularly due to the rare occurrences of graptolites.
根据宜昌陈家河剖面大湾组的笔石标本,确立笔石序列自下而上为:Didymograptellus eobifidus带、Corymbograptus deflexus带和Azygograptus suecicus带(大湾组下段),Exigraptus clavus带和Undulogr aptusaustrodentatus带(大湾组上段)。
Based on the analysis and study of poptolite fossil data from well Tazhong 29 in Tdrim Basin, it is considered that the geologic time of the graptolites is Middle Ordovician and early Late Oniovician,approximately corresponding to Caradoc in westem Europe.
