Here we report a new iguanodontian dentary found from the Lower Cretaceous Khok Kruat Formation,Nakhon Ratchasima,northeast Thailand.A unique character,which is an elongated and flat shape of the dentary ramus,makes it possible to assign the specimen to the new genus of non-hadrosaurid iguanodontian,Ratchasimasaurus suranareae *** *** shows both primitive and derived characters,such as a caudally inclined coronoid process and alveolar trough with a primitive crown impression,and a derived buccal shelf between tooth row and coronoid *** discovery of a new iguanodontian from the Indochina Terrene,considering that the previously reported 'Probactrosaurus-like' iguanodontian,points out a great diversity of this group in the late Early Cretaceous in Thailand,and corresponds to the Asian iguanodontian diversity at that time.

Mesozoic to Cenozoic petrified woods are very rich and well preserved in the Khorat Plateau, Northeast Thailand, serving 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.

泰国东北部柯叻府及邻区特有生物化石的研究近年来引起地质古生物学界的广泛关注。该地区中新生代木化石非常丰富,并具有保存完好的解剖构造,成为了解热带植被历史和气候演化以及古地理环境变迁等问题的重要实证材料。通过新的联合野外调查和室内专题解剖研究,查明该地区中新生代木材化石在种级水平上的分类学属性,确认19属约50个种或种级分类单元,分别隶属于11个科以及裸子植物和被子植物两大分类群。
