通过对中国化石骨舌鱼类及骨舌鱼类现生主要类群的比较研究,用 PAUP 软件对31个分类单元的65个特征进行了分析,得到了16个最简约的分支图(步长为206,一致性指数为 0．4320,保留指数为0．7194)。严格合意树显示,中国早白垩世的骨舌鱼类(酒泉鱼、狼鳍鱼、固阳鱼、吉南鱼、同心鱼、西夏鱼、昆都仑鱼和华夏鱼)主要为骨舌鱼超目中不同等级的干群；与一般的观点不同,始舌齿鱼与蛟河鱼组成了姊妹群关系；骨舌鱼目由 Thaumaturus、弓背鱼亚目和骨舌鱼亚目组成；弓背鱼类与象鼻鱼类关系更近；Ostariostoma 为弓背鱼科的姊妹群；副狼鳍鱼与[骨舌鱼亚科+犁齿鱼亚科]组成了姊妹群,该姊妹群关系的建立,将骨舌鱼科的历史延伸到了早白垩世。
Through the comparative study of the main living groups of fossil fossils and fossil fishes in China, 65 features of 31 taxa were analyzed by PAUP software, and the 16 most simple branches were obtained 206, consistency index 0.4320, retention index 0.7194). Strict congenial tree shows that the early Cretaceous China’s turtle fish (Jiuquan, Langyu, Guyang, Guinanus, concentric, Xixiayu, Qindulun and Huaxiayu) mainly for Gracilaria Different from the general point of view, different from the general point of view, the tongue teeth fish and Jiaohe fish formed a sister group relationship; the tongue turtle by Thaumaturus, Arched fish and bone tongue suborder fish; Ostariostoma is a sibling group of Archidae, and Sophori fin fish form a sister group with [Bifidobacterium subfamily + Dendrolimus subfamily]. The establishment of this sibling group relationship, Extending the history of the Osteidae to Early Cretaceous.
