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.
