摘要: 在塔里木盆地杜瓦地区早三叠世地层(乌尊萨依组)中,发现了孢粉、大孢子、叶肢介、鱼和疑源类等化石。其中以孢粉化石最为丰富,共发现孢粉50属,67种,根据这些孢粉化石建立了一个孢粉组合,命名为Taeniaesporites-Camptotriletes组合,这些化石的发现,为建立皮山杜瓦地区早三叠世生物地层奠定了基础。

Abstract: The fossils such as sporopollen, big spore, conchostraca, fish and acritarch etc. were found in Wuzunsayi formation(Early Tnassic) in Duwa section of Tarim basin, among which the sporopollen prevails with 50 genus and 67 species. A sporopollen assemblage was established based on the sporojx)llen fossils, named Taemaesporites-Camptotriletes assemblage. Synthetic use of these fossils gives a solid biostratigraphic foundation of Elarly; Tnassic in Duwa area.
