摘　　要：潮水盆地潮参 1井发现 Darwinula- Timiriasevia化石组合 ,化石丰富 ,保存完好 ,组合特征显示其地质时代为中侏罗世晚期。The fossil ostracods reported here were collected from the Jurassic of the Chaocan 1 hole in east Chaoshui Basin,Gansu. They contain 16 species in 2 genera, including Darwinula impudica,D. sarytimenensis,D. magna,D. xiaoxiaensis,D. longula,D. agitibilis,D. protensa,D. jinhuaensis,D . sp.1, D . sp.2, D . sp., Timiriasevia mackerrowi,T. gracilis,T. incognata,T . cf. humilis ,and T. catenularia . This ostracod assemblage is similar to those found from the Middle Jurassic in Xining, North Shanxi, Henan, Yunan, Sichuan and Xinjiang, and analogous to the ostracod assemblages Middle Jurrassic in Kazakhstan and Oxford in England. This ostracod assemblages is considered to be late Middle Jurassic in age.
