摘　　要：Mesozoic to Cenozoic petrified woods are very rich and well preserved in the Khorat Plateau, Northeast Thailand, serv ing as remarkable material for investigations of tropical vegetation history, paleoclimatic evolution, and paleoenvironmental changes. Our recent field survey and investigations have defined about 50 species of fossil wood assigned to 19 genera and 11 families from Mesozoic to Cenozoic deposits in this region. These woods are ascribed to two groups, gymnosperms and angiosperms. Among them, about 20 species assigned to 7 genera and 5 families are the first reports of the taxa in Thailand. The fossil wood floras indicate that during the late Mesozoic period, the tropical conifer vegetation in Northeast Thailand was dominated by the family Araucariaceae. From the Miocene to Pleistocene, a tropical climate prevailed in this region with perhaps both deciduous and evergreen broadleaf forests comprising the vegetation.到新生代的中生代石化森林很富于 Khorat 高原，东北泰国，为热带植被历史的调查的服务同样显著的材料， paleoclimatic 进化，和 paleoclimatic 、很好保存进化，和 paleoenvironmental 变化。外面最近的领域调查和调查定义在这个区域从中生代分到 19 个类和 11 个家庭到新生代存款的石块木头的大约 50 种类。这些森林被归功于到二个组，裸子植物和被子植物。在他们之中，分到 7 个类和 5 个家庭的大约 20 种类是税的第一份报告一在里面泰国。石块木头植物群显示在迟了的中生代时期期间，在东北泰国的热带针叶树植被被家庭 Araucariaceae 统治。从对更新世中新世，热带气候在这个区域占优势与也许包括植被的脱落、常绿树的阔叶烟草森林。
