Progress has been made in the paleo-ecological research of the mammoth-haired rhinoceros herd in Northeast Asia

A data map of carbon-nitrogen isotopes of the cave animal populations of the Yanjiagang and Geographical Society
the mammoths of the late Octinate northern hemisphere - the furry rhinoceros herd is known for the flourishing of herbivores such as real mammoths, furry rhinos, and grassland bison. However, after the end of the latest world, nearly half of the species in the herd went extinct. International academic attention to the mammoth-haired rhinoceros population is very high, but in northeast Asia, the southeastern boundary of the distribution of the herd, related research has stagnated in recent decades.
Recently, researchers such as Ma Wei of the Institute of Paleovertebrates and Paleoanthropology of the Chinese Academy of Sciences, Wang Yuan and Hu Yaowu of Fudan University, and Herv? Bocherens of the University of Tubingen, Germany, made comprehensive use of a variety of biogeochemical research methods to carry out systematic paleo-ecological research on mammoth-haired rhinoceros populations in the Shaojiagang site in Heilongjiang Province and the geographical society caves in the Russian Far East. The findings were published online in the International Fourth Era.
carbon-nitrogen stable isotope analysis revealed that the real mammoths at both sites were the main food sources for herring and moss, while the food sources of animals such as woolly rhinos and bison were more flexible and diverse than 3 mammoths. The animal archaeology analysis based on mass spectrometum not only provides accurate animal genus identification results, but also accurately identifies a sample of Wang's buffalo in Shaojiagang. The carbon XII results for multiple samples were 43,447/>41,964-38,204 14C BP, significantly earlier than those published at the Yanjiagang site in the 1980s.
Overall, the mammoth-haired rhinoceros herd in mid-latitude Northeast Asia presents a unique appearance compared with the high latitudes, because of the flat terrain in the eastern part of China, large mammals in the climate-turbulent MIS 3 stage may often occur north-south migration activities, thus shaping the true mammoth, woolly rhinoceros and other ice-resistant animals and warm buffalo co-existence of the unique face.
also revealed that the ancient environment of the cave of the Geographical Society is significantly different from that of the northeast region of China, and also reflects the environmental complexity of the southeastern boundary of the mammoth plain. In the future, systematic 1980s and paleo-ecological studies of mammoth-haired rhinoceros in different parts of northern China will redraw the unique evolution path of the animal group in China.
research has been supported by the Chinese Academy of Sciences strategic pilot science and technology special, the National Natural Science Foundation and other projects. (Source: Cui Xueqin, China Science Daily)
