摘要
迄今为止 ,我国共发现异木属 (Xenoxylon)化石木 1 0种 (包括 2新种 ) ,它们是X .latiporosum ,X .conchylianum ,X .liaoningense ,X .japonicum ,X .ellipticum ,X .hopeiense,X .peidense,X .yixianense,X .fuxinensesp .nov .,X .huolinhenesesp .nov .。文中对该属的古生态作了初步探讨 。
The specimens of the Mesozoic fossil wood Xenoxylon have been systematically collected and investigated in this study from eighteen localities in northeastern China. Six species known and two new species have been found, including Xenoxylon latiporosum, X. japonicum, X. ellipticum, X. hopeiense, X. peidense, X. yixianense, X. fuxinense sp. nov. and X. huolinhense sp. nov. In addition, two other species reported by previous authos were also identified as X.conchylianum and X. liaoningense. The palaeoecological environment model and phylogenesis of the genus Xenoxylon are analyzed and discussed here also.
