【Abstract】 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.更多还原
