Abstract: The late Early Devonian vertebrate fossils including antiarchs and polybranchiaspids were collected from Yuantou Valley, Pingle County of Eastem Guangxi. The antiarvh fossils were named Dayaoshania youngi by Wang Shitao in Ritchie et al. (1992), and referred to the Sinolepidae. Dayaoshania has no median ventral plate, similar to Liujingolepis, Xichonolepis and Sinolepis of South China and Grenfellaspis of Australia. In this paper the polybranchiaspid fossils are described, and the Discaspis pinglensis— Dayaoshania youngi Paleocommunity is termed, representing the late Early Devonian Paleocommunity in the Hexian Fomaüon of Guangxi (unnamed Paleocommunity in Wang, 1991).

摘要： 描述了产自广西东部平乐下泥盆统贺县组的一脊椎动物群中的无颌类化石，建立了盔甲鱼类的一新属、新种—平乐圆盘鱼(Discaspis pinglensis get. et sp. nov.)。圆盘鱼鳃囊数目多达32对。同层产出的尚有保存较完好的胴甲鱼目中华鱼科化石。该动物群的发现为华南区早泥盆世晚期脊椎动物群的演化及其生物地层的对比提供了重要依据。
