摘要: 本文记述了甘肃明水“龙凤山群”渝州鱼属(Yuchoulepis)一新种—甘肃渝州鱼(Y.gansuensis sp. nov)和金尾鱼科(Caturidae)一新属、新种—明水似凶暴鱼(Plesiofuro mingshuica gen. et sp. nov)。根据鱼化石性质,将含鱼化石地层的时代定为早侏罗世。

Abstract: The specimens of ganoid fishes described here were collected from Mingshui, Gansu by some geologists of a local field party. All the 35 specimens came from lower subgroup of "Longfengshan Group" (Early Jurassic). Sixte n of them are assigned to a new species of Yuchoulepis, Y. gansuensis, of the ptycholepidae. The other nineteen are referred to a new genus and species, Plesiofuro mingshuica, of the Caturidae. Early Jurassic fishes were previously rarely found in China, this new discovery is of great significance to the study of the ichthyofauna of the period.
