摘要： 本文记述的是采自云南武定中泥盆统地层中的一个总鳍类、骨鳞鱼目(Osteolepiformes Jarvik 1942)、骨鳞鱼科(Osteolepididae Cope 1889)的瑟索鱼属(Thursius)化石新种—武定瑟索鱼(Thursius wudingensis sp. nov.)。对骨鳞鱼化石的记述在国内尚属首次。本文除了对化石新种进行描述和分类之外，还对武定瑟索鱼的生物地理意义以及它与杨氏鱼的关系作了尝试性的探讨。
Abstract: A new osteolepidid crossopterigian, Thursius wudingenszs sp. nov., is described from the middle Devonian Haikou formation, Wuding, Yunnan, China. This is the first description of osteolepidid fish from China. The fossil materials were discovered in the quarry of Wuding cement factory in early 1960's. Several Placoderm forms from the same site were identified by Zhang Guorui (1965, 1980) as Dianolepis, Xichonolepis, and Bozhriolepis. Recently, more materials have been collected from the site. These and those collected years ago include most parts of the head of an osteolepidid fish. Since they are all cosmine covered, have the same color, similar thickness and size, it is natural to consider them as belonging to the same form. With reference to the description and plates of Scotland osteolepidid fish (Jarvik, 1948), these disarticulate dermal bones are recognized and reconstructed as an almost complete head. And a new species is set.
