近5年全球古脊椎动物新分类单元研究概况

Overview of New Taxa on Global Vertebrate Fossil during 2017-2021

古脊椎动物多样性数据资源是研究地球历史以及深时生命演化的重要信息来源,古脊椎动物物种名录是研究古脊椎动物多样性的重要基础,及时了解古脊椎动物分类单元数据的更新,可以实时掌握古脊椎动物多样性的研究热点,把握学科发展脉络。基于“深骨”数据库,文章利用文献计量学方法对近5年古脊椎动物不同类群新分类单元的年变化特征、分布地、发表期刊以及主要贡献的机构进行了梳理。分析结果显示,近5年全球新增古脊椎动物分类单元2662个,涉及文献1946篇,在2019年底新冠疫情爆发后,古脊椎动物新分类单元和文章数量均呈下降趋势。近5年全球古脊椎动物新分类单元模式标本主要分布在古脊椎动物化石资源丰富、经济和科研实力较强的国家,主要有美国、中国、新西兰、阿根廷和德国。Journal of Vertebrate Paleontology、Cretaceous Research、Historical Biology、PeerJ和Journal of Systematic Palaeontology等刊物是新分类单元发表的主要载刊,而贡献度最高的机构分别为中国科学院、俄罗斯科学院、阿根廷国家科学与技术研究理事会和美国自然历史博物馆等单位,且各机构的研究合作十分密切。中国古脊椎动物分类学的研究已处于世界领先水平,未来还应该继续加强古脊椎动物多样性基础数据积累,为探讨生物多样性的起源和演化提供支撑。

Biodiversity data of vertebrate fossils is important information source for studying earth history and life evolution.The species list of vertebrate fossils is an essential basis for studying the diversity of global vertebrate fossils.Reviewing new taxa and literature on vertebrate fossils can reveal the research hotspots of vertebrate fossils diversity and grasp disciplinary development directions on a time scale.Based on the DeepBone Database,this study reviews the annual variation characteristics of taxa and literature,distribution countries of the holotype,published journals,and significant contributing institutions of new taxa on the different categories of global vertebrate fossils during 2017-2021 using bibliometrics analysis.The result shows that 2662 new taxa emerged,and 1946 literature were published on global vertebrate fossils during 2017-2021.New taxa and literature on vertebrate fossils have decreased since the outbreak of COVID-19 at the end of 2019.Countries with a high distribution of the holotype of new taxa for global vertebrate fossils during 2017-2021 and are rich in vertebrate fossil resources,are strong in the economic and scientific research,mainly including the United States,China,New Zealand,Argentina,and Germany.Journal of Vertebrate Paleontology,Cretaceous Research,Historical Biology,PeerJ,and Journal of Systematic Palaeontology are the prominent journals on new taxa of vertebrate fossils.The institutions with a high contribution to the new taxa for vertebrate fossils are the Chinese Acad Sci,Russian Acad Sci,Consejo Nacl Invest Cient&Tecn,Nat Hist Museum,and the research cooperations of various institutions are very close.The study of taxonomy on vertebrate fossils in China has reached a high level in the world.We should continue to strengthen the accumulation of primary data on vertebrate fossils diversity to provide the DeepBone database for exploring the origin and evolution of biodiversity in the future.
