摘要
新疆柯坪大湾沟和甘肃平凉官庄剖面是 N emagraptus gracilis带及上奥陶统底界的重要剖面 ,研究这两剖面的牙形刺具有十分重要的意义。本文描述了采自新疆柯坪大湾沟和甘肃平凉官庄剖面上奥陶统底界附近的牙形刺共 13属
The Dawangou section of Kalpin area,Xinjiang and Guangzhuang section of Pingliang area,Gansu were proposed as the global stratotype for the base of the Nemagraptus gracilis Biozone and the base of the global Upper Ordivician Series.So the description of conodonts from these two sections is very improtant for the study of the stratotype section.This paper describes the conodonts of 18 species referred to 13 genera from the interval across the Upeer Ordovician Series in the Dawangou section of Kalpin,Xinjiang and Guangzhuang section of Pingliang Gansu.
