| 摘 要： | 在内蒙古西乌珠穆沁旗哈尔努尔山西南阿木山组剖面的一个层位中发现早二叠世牙形刺新种Neostreptognathodus costatus sp.nov.。根据牙形刺地层分布分析判断,该剖面地层是倒转的,但由于现有资料有限,地层是否连续或有缺失存疑;此剖面是否适合全部归入阿木山组,也有待进一步论证。期待能对此剖面重新详细的考察和大量采样,以便解决上述问题。

| Abstract: | A new species of conodont(Neostreptognathodus costatus sp.nov.)came from the horizon of the Amushan Formation in Xiwuzhumuqin Qi,Inner Mongolia,China.Based on the stratigraphic distribution of conodonts,the strata of the investigated section is found reversed.However whether the strata of the section is continuous or have some gaps,is not clear.Even the assignment of the all section to the Amushan Formation is also questionable.It is necessary to measure this section again and collect more abundant conodont samples. |
