【摘要】：在世界范围内,"贵州三叠纪化石群"是为数不多的三叠纪化石群产地之一。该生物群是海生爬行动物类、海百合类、脊椎动物类、无脊椎动物类、鱼类、植物类等为一体的生物群,世界罕见。为探究该化石群具有的潜在遗产价值,以对比的思想为指导,从化石群的古地理与古生态环境等几个方面为切入点,采用对比分析的方法,与世界范围内有关三叠纪生物群的世界遗产地或重要的、具有可比性的三叠纪生物群进行对比,探究其潜在的世界遗产价值和全球唯一性。结果表明:该地区在古地理上位于特提斯洋的东段,属于西特提斯古地理构架与东太平洋古地理构架的过渡地区,具有特殊性。同时,记录了三叠纪安尼期—卡尼期的连续完整的地质演化史与生物演化过程,代表着中生代古生物演化的重要阶段,在世界自然遗产提名中具有突出普遍价值。
[Abstract]:In the world, Guizhou Triassic Carbide Group is one of the few Triassic Carboniferous origin.The biota is a marine reptile, sea lily, vertebrate, invertebrate, fish, plant and so on, which is rare in the world.In order to explore the potential heritage value of the fossil rock group, a comparative analysis method is adopted from the aspects of paleogeography and paleo-ecological environment of the fossil rock group, under the guidance of the comparative thought, and from several aspects, such as paleogeography and paleo-ecological environment, etc.Compared with the world heritage sites or important and comparable Triassic biota in the world, the potential value and global uniqueness of the Triassic biota are explored.The results show that the region is located in the eastern part of the Tethys Ocean in paleogeography and belongs to the transitional region of the West Tethys paleogeographic framework and the eastern Pacific paleogeographic framework.At the same time, the continuous and complete geological evolution and biological evolution of the Triassic Annian-Carney period are recorded, representing an important stage of the Mesozoic paleontological evolution, which is of great universal value in the nomination of the World Natural Heritage.
