贵州纳庆(纳水)剖面莫斯科阶与卡西莫夫阶界线层牙形刺研究新进展

摘要：

　　The current base of the global Kasimovian Stage is raised to approximately the base of the Khamovnikian Substage．This level is approximately one substage higher than the traditional base of the Kasimovian at the base of the Krevyakinian Substage in the Moscow Basin of Russia，but it facilitates global correlation(Uenoand TaskGroup，2009)．<br>　　Either Idiognathodus sagittatis Kozitskaya, 1978 or Idiognathadus turbatus Rosscoe and Barrick, 2009a is the potential biostratigraphic marker by which the level of the base of the Kasimoviancan be selected and correlated globally.
