摘要: 记述了塔里木盆地下石炭统介形类化石。化石主要采自塔北井下双峰灰岩之上的央拜希组。自上而下有３个组合（１）Ｐａｒａｐａｒｃｈｉｔｅ Ｍｉｃｒｏｃｈｅｉｌｉｎｅｌａ Ｂａｉｒｄｉａ；（２）Ｐａｒａｃａｒｂｏｐｒｉｍｉｔｉａ Ｃａｖｅｌｉｎａ；（３）Ｈｅａｌｄｉａｎｅｌａ Ｂｙｔｈｏｃｙｐｒｉｓ。化石组合的地质时代为早石炭世中期—晚期。Abstract: The paper describes the Lower Carboniferous ostracodes in the Tarim basin. These fossils were mainly collected from a well drilled in the Yangbaixi Formation above the Shuangfeng limestone in the Tarim basin and include three assemblages from top to bottom: （1） Paraparchites Microcheilinella Bairdia; （2） Paracarboprimitia Cavcllina; and （3） Hcaldianclla Bythocypris. Their ages are mid late Early Carboniferous.
