| 摘 要： | 对新疆乌恰县塔塔村下侏罗统莎里塔什组孢粉植物群的研究，共发现孢粉２２属２６种，植物化石１２属１５种。根据这些孢粉化石建立了一个孢粉组合，命名为Ｃｙａｔｈｉｄｉｔｅｓ－Ｃｌａｓｓｏｐｏｌｌｉｓ组合，再根据侏罗纪的标志植物锥叶蕨（Ｃｏｎｉｏｐｔｅｒｉｓ）的存在，将莎里塔什组的时代确定为早侏罗世，为乌恰地区早侏罗世生物地层提供了可靠依据

| Abstract: | By study of sporopollen and flord of Lower Jurassic in Tata village of Uqar county in Xinjiang,the sporopollen of 22 gena and 26 species, and plant fossils of 12 gena and 15 species were discopered. One sporopollen assemblage was set up, nammed bas Cyathidites-Classopellis assemb1age according to sporopollen fossils. And the existence of Coniopteris, a marking plant of Jurassic, suggests the age of Shalitash FOrmation is early Jurassic. It so supplies a reliable basis for the building of early Jurassic biostratigraphy in the Uqar area. |
