| 摘 要： | 新疆西准噶尔哈拉也门地区原有一套地层划分为下石炭统和布克河组，岩性组合与标准剖面差异较大，因此，新建塔克台组.在该组参考剖面TK01第3层含化石的灰岩透镜体中，发现了少量非常重要的浅水相牙形刺，包括3属6种1未定种:Icriodus alternatus alternatus、Icriodus cornutus、Icriodus expansus、Polygnathus krestovnikovi、Polygnathus procerus、Polygnathus makhlinae、Ancyrognathus sp.，与这些牙形刺共生的还有软骨鱼类化石Protacrodus sp.和Phoebodus sp..该化石组合表明，新建的塔克台组的时代为晚泥盆世法门期早期.

| Abstract: | The Devonian Famennian conodont and chondrichthy have been found from the newly established Taketai Formation which previously was assigned to the Early Carboniferous Hebukehe Formation in Halayemen region, western Junggar. Conodont fossils include 3 genera, 6 species and 1 indeterminate species: Icriodus alternatus alternatus, Icriodus cornutus, Icriodus expansus, Icriodus sp.1, Icriodus sp.2, Polygnathus krestovnikovi, Polygnathus procerus, Polygnathus makhlinae, Polygnathus sp.1, Polygnathus sp.2, Polygnathus sp.3, Ancyrognathus sp.. Chondrichthyes include 2 genera: Protacrodus sp. and Phoebodus sp.. It indicates that Taketai Formation belongs to early Famennian of Late Devonian. |
