| 摘 要： | 黄河下游边滩泥质沉积物表面常遗留有鱼类的各种痕迹,有(1)游泳迹:包括由鲻鱼尾鳍刻划形成的各种线状延伸和非线状延伸的单一波线;臀鳍形成的线状延伸的单一波线;腹鳍紧贴泥质沉积物表面形成的平行成对波线;胸鳍扇动时形成的不平行断续成对波线;以及上述各种波线所形成的组合.(2)鲻鱼进食遗留下来的圆环状或圆坑状牧食迹,可组合成葡萄状、弧形、星点状、线状、"之"字形、带状等各种形态.(3)鱼粪.本文对上述各种鱼类痕迹的特征、成因、形成环境进行了详细阐述,并认为缓慢沉积的泥质沉积物表面是鱼迹形成并保存的前提.

| Abstract: | Many fish produced markings are well developed on the argillaceous sediment overlying the Yellow River point bar. They are: (1) swimming trace, i.e. the simple wave line elongating in the linear or nonlinear form due to the scratch of the tail fin of fish; the simple line elongating in the linear form induced by anal fin; the parallel paired wave line on the argillaceous sediment caused by the ventral fin; the intermittent discordant paired wave line caused by the swing of pectoral fin; and the combinations of wave lines above. (2) round or pit like pascichnia, combined together in the grape, curved, disperse, linear, zigzag, banded form etc, produced by the fish grazinging. (3) fecal pellet. In this paper, the feature, genesis, and the environment related to the fish produced markings are discussed in detail, and therefore inferring that the argillaceous sediment subsiding slowly is the prerequisite for the forming and preservation of fish produced markings. |
