本文记述了在贵州省威宁县兔街乡海着村下二叠统茅口阶中发现的旋齿鲨类———Hunanohelicoprionxiandongensis(仙洞湖南旋齿鲨 )并讨论了其牙列形态和牙组织性质。
The Helicoprionid fossil from the Lower Permian Maokou Stage in Weining of Guizhou Province is described in this paper. It is quite similar to the Holotype of Hunanohelicoprion xiandongensis Liu discovered from the upper part of the Lower Permian Qixia Stage in Lianyuan of Hunan Province in 1994 in morphology of the dentition and in structure of the teeth, except that the teeth are smaller and the marginal serrations of the cutting blade are somewhat fewer.
