| 摘 要： | 新疆巴楚小海子剖面发现的牙形刺被有关作者鉴定为Icriodus de formatus Han，并将弗拉斯阶-法门阶界线置于巴楚组中段底部，认为东河塘组的时代为弗拉斯期或更老。但巴楚小海子剖面的牙形刺不是Icriodus de formatus，泥盆系-石炭系的界线应划在巴楚组中段下部之内，东河塘组的时代很可能是法门期的。

| Abstract: | The conodonts from the Xiaohaizi section of the Bachu area in Xinjiang were identified by some authors as Icriodm deformatus, who placed the Frasnian-Famennian boundary at the base of the Middle Member of the Bachu Formation, and assigned the Donghetang Formation to the Frasnian in age. However, their identification is incorrect; it is not Icriodus deformatus, but may be a new species of Icriodm, in the late Famennian. The Devonian-Carboniferous boundary should fall within the lower part of the Middle Member of the Bachu Formation, and the Donghetang Formation may be Famennian in age. |
