摘　　要：赵兵等(2006)将羌塘盆地北部产有Codonofusiella-Gallowayinella组合带化石的拉卜查日组归入到上二叠统长兴阶的上部,将那益雄组归入长兴阶下部,可能是错误的。王成源等(1997)早已指出,Gallowayinella的时代是吴家坪期而不是盛金章所确认的长兴期的早期。拉卜查日组应归到吴家坪阶。二叠纪的主导化石门类是牙形刺而不是。The Lapuchari Formation bearing Codonofusiella-Gallowayinella was assigned to the Upper Changhsingian Stage by Zhao Bing et al. （2006）, based on the Sheng et al. ＇s （1980） conclusion that Gallowayinella is a zonal fossil for the lower part of the Changhsingian. But the range of Gallowayinella is only limited within the Wuchipingian as it was pointed out by Wang et al. （1997） based on the study of conodonts. Gallowayinella never appears in the Changhsingian. The Lapuchari Formation should be assigned to Wuchipingian rather than Changhsingian. Permian leading fossil groups are conodonts.
