中国水生蜥与潜龙名称合法性之争     

季燕南  王旭日  季强 《江苏地质》2014,38(1):12-16

热河生物群中有一种水生爬行动物,以长颈、长尾、小头颅为主要特征。在研究中,不同学者使用了不同的学名,构成了同物异名。简要回顾它的研究历史,主要讨论究竟哪一个学名是合法有效名称。根据国际动物学命名法规,认为中国水生蜥(Sinohydrosaurus)命名在先,是合法有效名称,而潜龙(Hyphalosaurus)为无效名称,应当废弃。  相似文献   

Two Early Cretaceous fishes discovered from the most northern area of China: implications for the palaeobiogeography of the Jehol Biota

From a newly discovered Early Cretaceous fossil site at the Sanlianhe Coal Mine in Tahe County, Heilongjiang Province, the most northern area in China, two freshwater fossil fish had been recovered. This paper reports their classifications and implications regarding the palaeobiogeography of the Jehol Biota. The fish assemblage consists of Yanosteus sp. (Acipenseriforms) and Sinamia sp. (Amiiformes). Both are important members of the well known Jehol Biota, and their occurrence supports the correlation of the Yiliekede Formation at Sanlianhe Coal Mine site with the Jiufotang Formation of West Liaoning. The remains of the Yanosteus sp. from this locality is the first known record of the genus other than in the Yan‐Liao area of China, and the specimens of Sinamia sp. is quite similar to what may be a new species of Sinamia from West Liaoning. The new fossil site represents the most northern site that is undoubtedly part of the extent of the Jehol Biota as currently understood. The northern Great Xing'an Range area is an important region that may link correlations between the Early Cretaceous continental biotas of China, Mongolia and Russia.
