Bubalus wansijocki
Bubalus wansijocki (sometimes misspelled Bubalus wansjocki) is an extinct species of water buffalo known from northern China during the Late Pleistocene. A 2014 study on extinct Chinese buffalo species indicates that the related Bubalus fudi is a subspecies of B. wansijocki. Paleoecology
Many of the faunal assemblages associated with Bubalus wansijocki indicate that it lived in a relatively warm and moist environment, with a mixture of grassland, forest and swamp. However, the period it lived in was associated with a cold environment and other assemblages its remains have been found in show it and other warm-adapted animals together with cold-adapted ones. It is now believed that northern China went through many short, abrupt periods of very warm and very cold climate change during the Late Pleistocene. References
