Late Pleistocene mammalian fauna from Wulanmulan Paleolithic Site, Nei Mongol, China

Discovered in 2010 with the construction of Landscape Park on the left bank of Wulanmulun River in Kangbashi District of Nei Mongol, Wulanmulun Paleolithic Site yielded large quantities of mammalian specimens during 2010-2012 rescue excavations. Identified fossil materials include Myospalax sp., Cricetulus sp., Microtus sp., Apodemus sp., Arvicola sp.?, Dipodidae gen. et sp. indet., Lepus sp., Mustelidae gen. et sp. indet., Coelodonta antiquitatis, Equus przewalskii, Camelus cf. C. knoblochi Megaloceros ordosianus and Gazella sp. The fauna analyses show that the paleoenvironment in Wulanmulun Site area might have been a mixture or mosaic of grassland and forest with some small streams and swamps. The fluctuation of annual temperature might have been high, with the winter very cold and the summer relatively warm. The Wulanmulun fauna is in the same paleozoogeographic sub-province as Baotou, Shiyu, Salawusu and Loufangzi faunas, different from that of the Xiaogushan and Yanjiagang faunas of Northeast China, and more different from that of the Dantu fauna of East China. The Wulanmulun area was suitable for the habitation of the late Paleolithic humans, and Wulanmulun fauna were their main hunting prey.
