摘　　要：本文记述的介形类化石采自塔里木盆地北部柯坪地区大湾沟剖面坎岭组 ,共计 8属 14种 ,其中包括 2新种和 3未定种。 Thrallella,Octonaria,Predarwinula三属为本介形类组合最为重要且最具特色的分子。据此推测 ,坎岭组时代为晚奥陶世中期 (Caradocian)。Ostracodes dealt with in this paper were collected from the Ordovician Kanling Formation in the Dawangou Section of the Tarim Basin, Xinjiang. 8 genera and 14 species are recognized. The Thrallella Octonaria Predarwinula assemblage is proposed.This assemblage may represent the Ordovician Caradocian.
