"Guizhou Triassic Fossil Sites World Heritage Nominated Property is a series of fossil Lägerstattens composed of rich, complete and well preserved early Mesozoic fossils including marine reptiles, fishes, crinoids, ammonoids, bivalves, brachiopods and arthropods, etc. The nominated property is located in the subtropical region. The whole property shows a unique evolutionary sequence, ranging from Panxian Fauna in Anisian of Middle Triassic, to Xingyi Fauna in Ladinian, Middle Triassic and to Guanling Biota in Carnian of Late Triassic, indicating unique paleontological and paleogeography features. Guizhou Triassic Fossil Sites World Heritage Nominated Property is an outstanding physical marker of the evolution of the marine life and the ecosystem after the end-Permian Mass Extinction. The fossils are featured with high diversity, rich species, high integrity and exquisite preservation, presenting a complete evolutionary sequence of marine life in the Early Mesozoic age from the dead dreariness after mass extinction to start recovery, radiating, reaching the peak and establishing stable new Mesozoic ecosystem. Guizhou Triassic Fossil Sites, featured with special geographical location, are located at the border of two major oceans: Tethys and Panthalassic Ocean in the world, connecting West Tethys Bio-geographic Realm and east Panthalassic Ocean. The above information indicates that Guizhou Triassic Fossil Sites Nominated Property is the most important fossil origin place in Middle and Late Triassic for marine life in the world and delivers important scientific research and protection value."
