On March 17th, the Chinese Paleontological Society released the selection results of the "Top Ten Advances in Chinese Paleontology in 2022" in Nanjing. A batch of scientific research achievements led by the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, China University of Geosciences (Wuhan), Peking University, Nanjing University, Chang'an University and other scientific research institutes and universities were selected. The "Top Ten Advances in Paleontology in China in 2022" selected this time include: the Silurian Fossil Pool reveals the rise and diversity of early jaw vertebrates; Paleogenomics reveal the formation history of Xinjiang's population over the past 5000 years; The ultrastructure revealed that Yunnan insects had primitive vertebrate pharyngeal bones; The crinkle cysticercus is an early molting animal, not the earliest hindmouth animal; Sexual selection promotes the specific evolution of the head and neck of giraffes; The pigment processing and innovative composite tool use of modern East Asian people 40000 years ago; Evolution of key ecological behaviors of Mesozoic insects; The world's first tiger paleogenome; Changes in atmospheric carbon dioxide content reveal the mechanism of mass extinction at the end of the Permian; Global warming and marine hypoxia under the late Paleozoic ice chamber climate (parallel progress 10); Volcanism and the impact of terrestrial ecosystem fluctuations at the turn of the Triassic Jurassic (Parallel Progress 10). The reporter learned from the Society of Paleontology that the selected scientific research achievements reached international standards. For example, "The Silurian Fossil Library Reveals the Rise and Diversity of Early Jawed Vertebrates" has discovered two unique fossil libraries in the world that preserve a large number of early Silurian (Landuoleian) jawed fossils, pushing forward the earliest record of fully preserved jawed fossils by about 11 million years, displaying previously completely unknown information such as the body structure and tooth development of fish 440 million years ago, It has greatly filled the key leap in the evolution of "from fish to man".
