Late Miocene mammalian fauna of Halajin Hushu in Nei Mongol,China
摘要
Abstract
Discoveries during the past 40 years of continental Neogene fossil sites in central Nei Mongol,through the adoption of screen washing techniques,have rapidly filled previous gaps in our knowledge of late Cenozoic faunal evolution and biochronology.Small mammals have become the backbone of our efforts in serializing individual fossil assemblages and in establishing a detailed framework of faunal sequence.We present another Late Miocene fauna from a new Halajin Hushu locality that,once again,shows the"embarrassing riches"of the Mongolian Plateau.The new locality is the northern-most fossil site in this region and is capped by a sheet of basalt.The new fossil assemblage is represented by 62 taxa of small mammals and one large mammal based on more than 7000 specimens.Our collections thus captured a remarkably complete small mammal fauna,possibly including 6 reworked species.Despite this mixture of reworked taxa from strata of older age,the Halajin hushu Fauna closely represents a coherent Late Miocene small mammal assemblage and its environments.Our preliminary analysis suggests a Bahean Chinese Land Mammal age in the early Late Miocene for the Halajin Hushu Fauna,probably slightly younger than Amuwusu Fauna but older than Shala Fauna.关键词
