禄丰古猿化石地点的鱼化石

FISH FOSSILS FROM THE HOMINOIDE BEARING LOCALITY AT SHIHUIBA, LUFENG, YUNNAN

在禄丰古猿化石产地采获许多鲤的咽喉齿化石,由形态特征看,相近于现代广泛分布的鲤(Cyprinus carpio Linn.)的咽喉齿,当代表其早期记录。现今云南一带生存有多种鲤,可能为其繁衍的后代,且相当繁盛。这一发现为鲤属(Cyprinus)起源于亚洲提供了化石依据。

Fish remains described here were collected from the fossil ape site of Lufeng, Yunnan. They were represented by numerous lower pharyngeal teeth. Judging from the morphological characteristics of the pharyngeal teeth, fin-spines, and other characters, it is apparent that all of them belong to the genus Cyprinus and one species only. The shape and the pattern of masticating surface of these teeth are similar to those of the common Chinese carp, Cyprinus carpio Linnaeus. This species is widely spreaded in Asia at present time. Therefore the data of Miocene carp in this district is valuable in the study of the appearence and the distribution of this genus. It seems to me that fossil carp occurred there represent the early member of this species. Nowadays, there are many species and subspecies of Cyprinus in this region. It indicates that Cyprinus carpio has a long existent history and gave rise numerous offsprings. Basing upon this the author inclines to conclude that Cyprinus is a native fresh-water fish in China, and Bast Asia is the place of its origin. From the habit of carp we can recognize that the fish-bearing beds are lacustrine deposits, and had a warm, humid climate during late Miocene.
