中国内蒙古中部地区新近纪小哺乳动物化石(2016)

内蒙古中部新近纪地层发育，哺乳动物化石丰富，是研究近代脊椎动物演化和新生代生物地层学的理想地区。本书对1995年以来在该区发现的啮齿动物化石进行了详细研究，共记述15科、82属、144种，其中包括10新属、53新种。这一地区发现的新近纪啮齿动物，占中国北方同期已知属和种的三分之二以上，分布于从早中新世至早上新世大部分时段的堆积物之中，组合成18个动物群，其中包括中国、甚至亚洲新近纪某一时段含化石最丰富、种类最多的几个动物群。根据动物的系统演化关系，本书对这些动物群进行了先后排序，并与欧亚时代接近的动物群做了对比。书中还探讨了啮齿动物各科在内蒙古中部地区的演化历史，阐述了各属的地理分布，推测了不同地质时期的生态环境，诠释了这一地区啮齿动物的多样性及其在中国新近纪陆生哺乳动物年代地层系统（LMS /A）框架内各个时期的组成特征。
本书是新近纪地层古生物学研究的重要参考书，可供国内外地质科研人员、大专院校地质教学人员和自然博物馆科研工作者参考使用。

Central Inner Mongolia has well-developed Neogene strata and is rich in mammalian fossils, making it an ideal locality for studying Cenozoic vertebrate evolution and biostratigraphy. This book provides a detailed study of rodent fossils discovered in this area since 1995, documenting a total of 144 species belonging to 82 genera and 15 families, including 10 new genera and 53 new species. The Neogene rodents discovered in this region account for more than two-thirds of the known coeval genera and species of rodents in northern China. Their remains are preserved in deposits spanning most of the interval from the Early Miocene to the Early Pliocene, and they form 18 faunal assemblages, among which are some of the most fossil-rich and species-diverse faunas in the Neogene of China and even Asia. Based on the phylogenetic relationships of the rodents, this book arranges these faunal assemblages in chronological order and compares them with coeval faunas from Eurasia. Additionally, the book discusses the evolutionary history of each rodent family in central Inner Mongolia, elaborates on the geographic distribution of each genus, reconstructs the paleoenvironmental conditions of different geological periods, and interprets the rodent diversity of this region and its compositional characteristics at each stage within the framework of the Chinese Neogene Land Mammal Age (LMS/A) chronostratigraphic system. This book is an important reference work for Neogene stratigraphic paleontology research, and can be utilized by geological researchers at home and abroad, geology faculty in colleges and universities, and scientific researchers in natural museums.
