| 摘 要： | 本文记述了产自长兴阶层型剖面下部的龙鱼化石,其特征与已知属种皆有区别,而与 Saurichthys madagascariensis Piveteau 比较相似.但在鳍的大小,鳞片行数等方面有所不同,今命名为赵氏始龙鱼 (Eosaurichthys chaoi gen. et sp. nov.). 它代表已知龙鱼中最早的记录,证明古生代末期,亚洲这一区域已有龙鱼分布.始龙鱼的发现对了解该类鱼的分布,二叠三叠纪鱼群的演替,以及古地中海的范围,均有重要意义.本文还讨论了龙鱼类鳞列的演变等.

| Abstract: | A new form of saurichthyid, Eosaurichthys chaoi gen. et sp. nov., discovered from the Changhsingian (Upper most Permian) is mainly characterized by its remarkably small fins and particular arrangement of squamation. The lithofacies of Changhsingian which is situated at Meishan coal field is composed almost of deep grey bituminous limestone with cherty bands, 40.39 m in total thickness (Zhao et al., 1981). Many fossil fishes have been collected from the lower part of this limestone sequence. |
