摘要: Abstract. The non-marine Mesozoic sedimentary rocks of Thailand, which consist the Indochina block and Sibumasu block, have yielded several terrestrial aquatic vertebrate fossils, but only few amphibian remains been reported. Here, we present an overview on Thai amphibian palaeo-diversity based literature, re-examination of published material, new findings, unpublished material. Thai amphibian fossil remains are assigned to Stereospondyli (Cyclotosauridae, Plagiosauridae, Brachyopoidea) Anura were discovered from four formations, ranging Upper Triassic Lower Cretaceous Thailand. The occurrence Brachyopidae in Thailand, which related Chinese forms, supports previous hypothesis physical connections between the Indochina blocks during era.
