西藏志留纪牙形石化石丰富,保存较好,数量众多,可建立能与欧美地区进行对比的 6个化石带和2个动物群。其中3个化石带是国内迄今未曾报道的。牙形石样品是作者等 1980—1981年间采集于西藏南部喜马拉雅北侧聂拉木一定日一定结一带和西藏北部湖区申扎地区。我国志留纪牙形石的研究起步略晚,报道较少,目前仅在云南、贵州、陕西等地有另星发现。像西藏地区这样比较完整的志留纪牙形石动物群在我国其它地区尚报道不多。 Tibet Silurian conodont fossils are abundant, well preserved and numerous in number. Six fossil belts and two fauna can be established for comparison with the European and American regions. Three of these fossil belts have not been reported in China so far. Specimens of conodont were collected by the author from 1980 to 1981 in the certain knot of Nyalam northern part of northern Himalayas in southern Tibet and the Xainza area in the northern lake area of ​​Tibet. The study of Silurian conodonts in China started a little later, with fewer reports. At present, there are only other stars found in Yunnan, Guizhou and Shaanxi provinces. Like the Tibetan region, the Silurian conodont fauna is still relatively small in other parts of our country.
