三叠纪鱼类在中国分布广泛。与当时“南海北陆”的古地理格局一致,淡水鱼类主要分布于北方大陆的河湖相盆地,但也见于扬子板块与北方大陆碰撞后的四川盆地；海生鱼类则主要分布于华南和喜马拉雅地区。值得注意的是,鄂尔多斯盆地已知的三叠纪鱼类中,多数为海生类型或与海生鱼类密切相关。中国的淡水三叠纪鱼群主要由原始辐鳍鱼类组成,它们与西伯利亚和中亚的鱼群最为相近,但也有与劳业大陆其他地区及冈瓦纳大陆的鱼类相似的属种。海生鱼群则以“亚全骨鱼类”为主,并包含鲱亚部的进步类群和真骨鱼类的基干类型。华南扬子区拉丁至卡尼早期的鱼群远较早三叠世的鱼群丰富,且这一时期的鱼群与西特提斯同期的鱼群关系已极为密切,约有1/3的种类可归入相同的属。华南中下扬子区很可能是部分后来繁盛于特提斯区的三叠纪鱼类的发源地,如龙鱼类。中国的三叠纪鱼类虽然十分丰富,但大多已知鱼类仅限于零星发现和初步报道,因而仍有待全面深入的调查研究。 Triassic fish widely distributed in China. Consistent with the paleogeography of the “South China Sea and Hokuru” at the time, freshwater fish were mainly distributed in the rivers and lakes of the northern mainland, but also in the Sichuan Basin after the collision of the Yangtze Plate with the northern mainland. The marine fish were mainly distributed in southern China And the Himalayas. It is noteworthy that most of Triassic fish known in the Ordos Basin are of the marine type or closely related to marine fish. The freshwater Triassic fish stocks in China consist mainly of primitive radiating finfish, which most closely resemble fish stocks in Siberia and Central Asia, but also have similar species to fishes in the rest of the continent and Gondwanaland. Marine fish stocks are predominantly “sub-full-bone fish” and include the herring sub-group of progressive and skeletonfish types. The latin to kani early Yangtze Delta in South China was more abundant than the Early Triassic, and the relationship between the fish in this period and that in the same period of the same period was very close. About one third of species Can belong to the same genus. The middle and lower Yangtze region in South China is likely to be the cradle of some Triassic fish that later flourished in the Tethys, such as the Arowana. Although the Triassic fishes in China are abundant, most of the known fishes are limited to sporadic discoveries and preliminary reports. Therefore, there is still a need for a comprehensive and in-depth investigation.
