摘　　要：在东准噶尔二台地区纳尔曼德山一带一套海相火山岩建造夹少量陆源碎屑岩地层中首次发现晚泥盆世菊石类Kosmoclymenia cf.tabulata Sun et Shen.(板状宇宙海神石(相似种)),为晚泥盆世顶部法门阶顶部层位的标志性化石,从而为厘定上泥盆统卡西翁组提供了重要的生物依据。In Naerdeman mountain,Ertai area,eastern Junggar basin,Xinjiang,Late Devonian Ammonoids Kosmoclymenia cf.tabulata Sun et Shen has been discovered in a marine volcanic and terrigenous clastic formation for the first time.This fossil is the iconic fossil for the top of Late Devonian Famennian.It provides an important paleontological basis for regional stratigraphic correlation of the Upper Devonian Kaixiweng formation.
