摘    要:比较了已经描述的新铺龙(Xinpusaurus)的三个种,确定以往确立的种间鉴别特征是无效的。吻部比例以及齿骨形态都不能用来区分它们,戈氏种(X.kohi)的头后骨骼鉴别特征基础不牢,大多因标本保存欠佳不能明确其有效性。因此,建议废除巴毛林种(X.bamaolinensis)以及戈氏种,新铺龙属仅保留属型种——孙氏新铺龙(X.suni)——为有效种。文中还进一步阐明了本属种脑颅的形态。

关 键 词:贵州关岭  三叠纪  海龙

Abstract:After examining the holotypes and the referred specimens of three species of Xinpusaurus, I conclude that the snout and the shape of the dentary cannot be used to differentiate the known species of Xinpusaurus and that the postcranial diagnostic characters of X. kohi cannot be confirmed because of the poor preservation; so both X. bamaolinensis and X. kohi should be junior synonyms of X. suni. The anatomy of the braincase of this taxon is further clarified.
Keywords:Guanling  Guizhou  Triassic  Thalattosauria
