| 摘 要： | 首次报道新疆伊宁地区下侏罗统八道湾组叶肢介化石１新属２新种（Ｉｌｉｅｓｔｈｅｒｉａｎｉｌｋａｅｎｓｉｓｇｅｎ．ｅｔｓｐ．ｎｏｖ．；Ｉ．ｘｉｎｊｉａｎｇｅｎｓｉｓｇｅｎ．ｅｔｓｐ．ｎｏｖ．）。其装饰特征与已知侏罗纪早、中期的类型有一定的相似性。据叶肢介在地层中分布特点及保存状况，认为其生活在浅水的湖沼环境并属于原地埋藏。

| Abstract: | The widespread Jurassic strata in Xinjiang of NW China contain comparatively abundant conchostracans(Novojilov, 1958 1 Zhang Wentang et al.,19761 Wang St-en, 1985),but the Early Jurassic conchostracans are relatively rare, especially in the lower LowerJurassic Badaowan Formation. The conchostracans described here come from the LowerJurassic Badaowan Formation in the Hongguang Pasture-ground, Nilka County, Xinjiang.Most samples possess well-preserved ornamentation on the growth bands of the valve. Anew genus and two new species (lliestheria nilkaensis gen. et sp. nov. 1 I. xinjiang6nsisgen. et sp. nov.)have been established, using scanning electron microscope. |
