| 摘 要： | 本文记述了新疆柯坪志留纪塔塔埃尔塔格组中发现的盔甲鱼类一新种,张氏南疆鱼 Nanjiangaspis zhangi sp.nov.)和汉阳鱼类一未定种(Hanyangaspis sp.).前者以横椭圆形的前中背孔,7对侧横管,2对背中管等特征归于南疆鱼属,并以瘤点状纹饰等特征区别于南疆鱼属型种;后者的前腹片特征和雪花状纹饰表明其归属于汉阳鱼类,在前腹片形状上与属型种稍有一些区别.文中还记述了一件发现于克兹尔塔格组的节甲鱼类化石(Arthrodira indet.).

| Abstract: | Two new sorts of galeaspids,Nanjiangaspis zhangi sp.nov.and Hanyangaspis sp.,discovered in Silurian Tataertag Formation of Kalpin in northwestern Tarim Basin of Xinjiang,are described in this paper.The former is characteristized by transverse eclipse-shaped median dorsal opening,7 pairs of transverse branches of lateral dorsal canals and 2 pairs of median dorsal commissures,and tuberculate ornaments,whereas the latter is similar to the type species in its anterior ventral plate and its tesserae ornament,but shows slight difference in the shape of its anterior ventral plate.Besides,an anterior ventral lateral plate belonging to Arthrodira is also reported in this paper,which is found in the Kezirtag Formation and represents the first report of arthrodire fishes in the Tarim basin. |
