text: Fossil evidence suggests that yak were extensively distributed in north-eastern Eurasia in the late Tertiary period (2.5 million years ago) and that these are the forerunners of wild yak found as Pleistocene fossils in northern China, Inner Mongolia (China), eastern Siberia and northern mid-Asia and on a line roughly connecting these locations (Dyblor, 1957; Belyar, 1980; Flerow, 1980; Olsen, 1991; but see also Chapter 15, Systematics and phylogeny).
