中文摘要	详细描述我国新疆塔克拉玛干沙漠东北部轮南探区50井的中-上奥陶统界线附近的牙形刺动物群,包括 Pygodus anserinus,P. serra,P. xinj iangensis, Ansella jemtlandica,Cornuodus longibasis,Periodon aculeatus, Protopanderodus calceatus, P. cooperi,P. uaricostatus,Scabbardella altipes,Spinodus spinatus 和 Cahabagnathus sweeti 等,由上而下可划分 Pygodus anserinus,P. serra 和 P. xinjiangensis 等3个牙形刺带,并以Pygodus anserinus 带的底界稍偏上处视为中-上奥陶统界线。尤为重要的是,本文对Pygodus xinjiangensis的有效性、Pygodus 属的演化趋势及其3个种的区别进行详细讨论,同时说明Pygodus anserinus由P. serra演化而来。
英文摘要	Conodont faunas from the Middle and Upper Ordovician boundary interval are recorded from Ln 50 well in the Lunnan exploration area, northwestern Taklimakan Desert, Xinjiang, China. The fauna includes Pygodus anserinus,P. serra, P. xinjiangensis,Ansella jemtlandica,Cornuodus longibasis,Periodon aculeatus, Proto panderodus calceatus, P. cooperi, P. varicostatus, Scabbardella altipes, Spinodus spinatus, and Cahabag-nathus sweeti, etc. Three conodont zones can be recognized. In descending order they are the Pygodus anserinus, P. serra and P. xinjiangensis zones. The Middle and Upper Ordovician boundary is just above the base of Pygodus anserinus Zone. In this paper, particular attention is paid to Pygodus xinjiangensis, the evolution of Pygodus, and the differences between these three species. Because species of Pygodus are of extraordinary importance for global correlation, the results of present study, which have clarified some taxo-nomic problems within this genus,are of international significance.
