Based on the conodont data, the evolutionary sequence of the Ordovician conodonts in the platform facies of the Tarim Basin was cleaned, one assemblage and 7 biozones are revised. After the cleaning, there are 1 assemblage and 20 biozones across the Ordovician in ascending order in the platform facies region of the Tarim Basin.
基于所获得的牙形石系统资料，对塔里木盆地奥陶纪台地相区已建牙形石生物地层序列进行了清理，确定了1个牙形石组合和20个牙形石带，据新的资料对8个原有的生物地层单元作了厘定。

In a pelagic chert section at Dachongling of Xiaodong town in the Qinzhou area of southeast Guangxi, we found stratigraphically continuous condont fossils, and divided them into two conodont zones, namely, Jinogondolella granti zone and Clarkina dukouensis zone, in ascending order.
在广西钦州地区小董镇大虫岭深海硅质岩剖面中，首次处理出了层序连续的牙形石化石，并由老至新划分了二个牙形石带，即Jinogondolella granti带和Clarkina ducouensis带。

Among them,the chitinozoan succession in the Fenxiang Formation in West Hubei is the most complete Early Ordovician (Late Tremadocian to Early Arenigian) chitinozoan succession which have been not ever found in the world so far. The result on the precise subdivisions and corelations of the chitinozoan and graptolite and conodont biozone of Dawan Formation at Huanghuachang strongly supports the Huanghuachang section as the Global Stratotype Section and Point for the base of Middle Ordovician.
其中，有关在鄂西地区分乡页岩中所发现的连续保存的几丁虫序列是目前世界上早奥陶世晚特里马道克世-早阿伦尼克世最完整的几丁虫序列；宜昌黄花场奥陶系大湾组几丁虫、笔石和牙形石精细生物地层划分和对比的研究成果，为宜昌黄花场剖面最终竞争成为全球中奥陶统底界界线层型剖面和点奠定了坚实的基础。
