摘要
对甘肃靖远一带和内蒙古自治区黑山地区早石炭世前黑山组、臭牛沟组和靖远组中三亚纲鱼类微体化石进行了形态学和古组织学研究。这些化石涉及 7个目或亚目 ,含 4属 4种 ,其中有 2新种。文中记述的属均为全球广布的属。建立了 3个早石炭世鱼类组合 ,这是我国早石炭世第一个鱼类组合序列。辐鳍鱼类和软骨鱼类中
Carboniferous fishes have been found from localities of the east sector of north Qilian Mountain, north China, the majority in Jingyuan County, Gansu Province. The Carboniferous of the east sector of north Qilian Mountain, typical marine alternating with non marine facies, has been subdivided lithologically into Qianheishan (Tournaisian Visean), Chouniugou (Visean), Jingyuan (Serpukhovian), Hongtuwa (Bashkirian), Yanghukou (Bashkirian, Moscovian and Kazimovian) and Jingci (Gzhelian) Formations (Li et al., 1974;Wu et al., 1987; Yang et al., 1997). In this paper we examine in detail the Lower Carboniferous microvertebrate fossils from Heishan area of Nei Mongol and Jingyuan, Gansu Province, and give the fish assemblage sequence in Qianheishan, Chouniugou and Jingyuan formations (Early Carboniferous). The early Carboniferous Actinopterygians and Elasmobranchians: Xenacanthida and Hybodontiformes are the first record from China. The material described here is housed in the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Chinese Academy of Sciences.
