摘　　要：记述了云南丽江县鸣音区阿冷初早泥盆世山江组 (Lochkovian EarlyPragian)和阿冷初组(Middle LatePragian)棘鱼亚纲微体化石。这些化石被归属于 4属 5种 ,其中包含 1新属 2新种。这是西藏—滇西区棘鱼类化石的首次报道。不同于华南区棘鱼类的组成 ,丽江早泥盆世棘鱼类以栅棘鱼目属种为主 ,缺少锉棘鱼目属种。它与国外对比 。Acanthodian scales were discovered from the Shanjiang Formation and the Alengchu Formation (Early Devonian) in Alengchu area, Mingyin District, Lijiang County, Yunnan, China. 4 scale genera and 5 scale species are described with 1 new genus and 2 new species.\;This is the first report on the occurrence of acanthodian fossils in Tibet western Yunnan region. Different from the Early Devonian acanthodian constitution in South China region, the Early Devonian acanthodian assemblage at Alengchu mainly consists of the genera and species of Climatiida, lacking representatives of Ischnacanthida. It suggests many similarities to the assemblage of the same age in Centeral New South Wales, Australia.\;This paper is from the author's master thesis supervised by Professor Wang Nianzhong. The materials described are housed in the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP), Beijing, China.
