| 摘 要： | 根据早期脊椎动物化石证据及生物地层对比,云南曲靖穿洞组的时代为晚Emsian期。该地区下、中泥盆统界线应划在穿洞组与海口组之间,或从穿洞组顶部穿过。

On the Lower-Middle Devonian Boundary in Qujing, Yunnan |

| Abstract: | On the basis of the evidences of early vertebrates and biostratigraphic correlations, it is suggested that the age of the Chuandong Formation (Qujing, Yunnan) is Late Emsian, and the Lower-Middle Devonian boundary may be drawn between the Chuandong Formation and the Haikou Formation, or through the top of the Chuandong Formation. |
