| 摘 要： | 本文记了塔里木盆地东北地区早二叠世介形类化石，化石采自柯坪县丘达依萨依剖面萨热哲依组，共计９属１５种，其中１０新种，并建立了Ｒｏｕｎｄｙｅｌｌａ－Ｈｅａｌｄｉａ－Ｓｕｌｃｅｌｌａ－Ｂａｉｒ－ｄｉａ介形类组合，此组合明显不同于以Ｂａｉｒｄｉａ为主的中国南方早二叠世介形类动物群。

| Abstract: | Ostracod fossils described in this paper were collected from the Sarezheyi Formation of the Qiudayisayi section in the northeast area of the Tarim basin. The formation consists lithologically of grayish brown calcareous lithic sandstone, siltstone and silty mudstone. Fossils are rich and include nine genera and 16 species, making up an ostracod fauna represented by Roundyella, Heal-dia, Sulcella and Bairdia. The more abundant forms are Roundyella and Healdia with subordinate Sulcella, Bairdia and Pseudoparaparchites. The new species form the bulk of the fauna, so the fauna displays a very strong endemic character, which makes the fauna notably different from the ostracod fauna dominated by Bairdia in Early Permian strata of southern China. The fossils associated with ostracods are fusulinids, conodonts and foraminifers. This fauna is Early Permian in age and it is inferred that it might belong to the forms living in a warm, semi-enclosed shallow-sea bay environment with weak hydrodynamic conditions. |
