摘　　要：重新研究了甘肃玉门含大山口动物群的地层,讨论了北祁连区二叠和三叠系划分,指出西大沟组存在误用,建议将上三叠统的西大沟组更名,将中二叠统产大山口动物群的西大沟组更名为青头山组,并将青头山剖面指定为青头山组命名剖面。After reexamining the horizon producing the Dashankou Fauna and the division of Permo-Triassic strata in northern Qianlian area,China,we found the misuse of the name ＂Xidagou Formation＂.Xidagou is held as group name for lower-middle Triassic of northern Qilian area,and cannot apply to other strata.We suggest rename former Xidagou Formation with Dashankou Fauna as Qingtoushan Formation and design the Qingtoushan section as the holostratotype;and the former Xidagou Formation applied to upper Triassic should be renamed.
