Abstract: In 1976, 1998 and 1999, vertebrate remains were collected at the second terrace along the northern and eastern banks of the Dabusu Lake (123°41′46″E, 44°43′45″N), located in the Qian’an County, Jilin Province of the People’s Republic of China. The fauna contains 19 species belonging to 6 orders, 12 families and 18 genera. The Dabusu Fauna is listed as follows: Struthio anderssoni, Marmota sp., Citellus sp., Canis lupus, Vulpes vulpes, Ursus arctos, Crocuta ultima, Panthera tigris, Mammuthus primigenius, Equus przewalskyi, E. hemionus, Coelodonta antiquitatis, Camelus knoblochi, Megaceros ordosianus, Cervus (E.) canadensis, Procapra przewalskyi, Bubalus sp., Bison exiguus, Bos primigenius. Most of the members of the Dabusu Fauna are important elements of the Mammuthus2Coelodon2 ta Fauna. So the Dabusu Fauna belongs to the Mammuthus-Coelodonta Fauna. The percentage of the extinct species in the Dabusu Fauna (36.84 %) is more than those of most other Late Pleistocene fauna , such as the Salawusu Fauna (33.3 %) (35 000aBP) , the Yushu Fauna (30 %) (31 800 ±900aBP) , the Antu Fauna ( 26 %) ( 30 000aBP), the Yanjiagang Fauna (25.9 %) (20 000aBP) , the Zhoukoudian Top Cave Fauna (12 %) (18 000aBP) , and the Qingshantou Fauna (8 %) (10 900aBP) , less than that of the Dingcun Fauna (5813 %) (90 000~60 000aBP) . However, the above relative ages based on the percentage of the extinct species do not wholly coordinate the 14C dating result of the Dabusu Fauna (20 530aBP), which should be studied further. Unlike the typical Mammuthus-Coelodonta Fauna, the members of the dry and cold prairie, such as Coelodonta antiquitatis, Equus przewalskyi, E. hemionus, and i etc., account for 52.63 % in the whole Dabusu Fauna. So during the age of the Dabusu Fauna, the climate was drier and colder than that of the most other Late Pleistocene faunas, which was similar to that of the Qingshantou Fauna near Dabusu. The analysis of the spore-pollen samples from the strata of the Dabusu Formation where the remains of the fauna were unearthed, shows nearly the same result of the climate trend during the period of the Dabusu Fauna.
摘要: 描述比较了在吉林省乾安县大布苏泡子新发现的鬣狗科化石Crocuta ultima。依据到目前为止所发现的6 目12 科18 属19 种脊椎动物化石组合,结合含化石地层的孢粉分析和14C 测年数据推测,大布苏一带在晚更新世晚期曾经以草原景观为主,兼有森林及荒漠,而且经历了从干凉草地向较潮湿凉爽的疏林或森林草原,直至干凉半荒漠草原环境变迁的历程。
