贵州关岭晚三叠世早期海生爬行动物Neosinasaurusnom.nov.

笔者在研究关岭晚三叠世早期海生爬行动物(见本刊上期1～23页)时曾命名中国龙属Sinasaurus Zhou (2000).现发现,"Sinasaurus"这个属名早在1940年就已被杨钟健教授研究描述肉食恐龙类Sinosaurus Young (1940)(见Young Z.J., Bull. Geol. Soc. China, 1940,XX (3～4):235～240)时所占用,Sinasaurus是晚出名,应废弃不用,现给与新名Neosinasaurus Zhou, nom. nov. 而替代Sinasaurus Zhou (2000).因Sinasaurus Zhou (2000) 为中国龙科的模式属,故将Sinasauridae Zhou (2000) 更名为新中国龙科(新名)Neosinasauridae Zhou nom.nov..现将Neosinasaurus和Xinpusaurus的分类位置列述如下
