    The mass extinction at the end of the Otau period was the first mass cluster extinction event suffered by the Earth's ecosystem since the birth of Zeus, and the first major transformation experienced since the origin and early evolution of paleozoic evolutionary fauna.
    extinction event ranks second among the five extinction events in biodiversity loss.
    In recent years, studies have concluded that the extent of the destruction of the ecosystem is disremmetred to the loss of its diversity, and that the loss to the ecosystem is far lower than that suffered by the other four mass extinction events, ranking only 6th or even 7th in the number of mass extinction events in the visible zeus.
    Recently, Huang Bing, a researcher at the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, and other benthic crustacean animal groups based on the residual period after the end of the Otao period in southern China (published in the form of monographs), analyzed in detail the ecological pattern of wrist-footed animals in the post-extinction period from aspects such as abundance models and benthic combinations.
    In order to further understand the ecological effects of mass extinction, Huang Bing and so on further compared the structure of similar molecular populations in two different wrist-footed animal groups before and after the mass extinction, so as to arrive at the ecological effect of the end of the Otao era at the community level, which is a brand-new attempt to study the mass extinction at the end of the Otao era.
    In addition, the analysis of the data on the diversity and benthic combination of wrist-footed animals in the residual period after the great extinction of the Otau period in the world, and the recent scholars' view that the "deep-water benthic combination of carpal-footed animals that do not exist or are rare after the end of the great extinction" have been questioned and importantly supplemented, and it is believed that South China is not necessarily a refuge for wrist-footed animals at the end of the Otau era.
    related studies also show that the ecological distribution of wrist-footed animal combinations before and after the end of the Otau era has not changed much, and the impact of mass extinction events on ecosystems may indeed be limited.
    By analyzing the performance of wrist-footed animal abundance and diversity data on the advanced classification order before and after the end of the Otao era in south China, it is confirmed that wrist-footed animals with the characteristics of the aspiring period began to appear in large numbers before the mass extinction and even tend to flourish locally, and the great extinction at the end of the Otao era only briefly broke the process of replacing the characteristic wrist-footed animals of the Otao era.
    the study explores the complex ecological effects of the end of the Otao period, from the population and benthic combination to the advanced classification order.
    results were published in Journal of Asia Earth Sciences.
