| 摘 要： | 摘要: 泰国东北部新生代硅化木十分丰富且保存完好。经对23 件木化石标本研究，已鉴定出真双子叶植物6 科7 属约13 种，包括Canarium sp． ( Burseraceae) ; Terminalia sp． vel Combretum sp． ，Terminalia sp． ( Combretaceae) ; cf． Irvingia sp． ( Irvingiaceae) ; Cynometroxylon holdeni，Cynometroxylon sp． ，cf． Cynometroxylon spp． ，cf． Millettia spp． ( Leguminosae) ; Careya spp. ( Lecythidaceae) ; Azadirachta sp． ( Meliaceae) ; 以及其他4 个分类群( 分类位置待定) 。这些高度分化的古植物群显示出与泰国东北部现存的混合落叶林、干旱阔叶林和干旱常绿林非常相似的特征，反映了该地区当时的古气候是近于湿润的热带疏林草原气候( 热带干湿气候) 。

| Abstract: | The Miocene-Pleistocene petrified woods are very abundant and well preserved in the area of Suranaree subdistrict,Nakhon Ratchasima,northeastern Thailand.Twenty three specimens of the petrified woods have been studied by the authors,and determined to comprise at least 17 species of 10 genera,including 13 eudicot angiosperm taxa assigned to 7 genera of 6 families.The taxa are Canarium sp.(Burseraceae);Terminalia sp.vel Combretum sp.,Terminalia sp.(Combretaceae);cf.Irvingia sp.(Irvingiaceae);Cynometroxylon holdeni,Cynometroxylon sp.,cf.Cynometroxylon spp.,cf.Millettia spp.(Leguminosae);Careya spp.(Lecythidaceae);and Azadirachta sp.(Meliaceae),etc.In addition,there are 4 taxa(incertae sedis) needed further study.The highly diverse paleoflora shows a close resemblance in the floristic characters to the modern flora of mixed deciduous,dry dipterocarp,and dry evergreen forests in northeastern Thailand,which implies that the paleoclimate in the area was probably tropical wet and dry,corresponding to the present climate but with higher humidity. |
