Size trends in Holarctic anchitherines (Mammalia, Equidae)

Size increase in European Miocene Anchitherium was described early in the century. Increase in size, particularly of the teeth, was common to the middle and late Miocene Eurasian Anchitherium and North American Hypohippus, including Megahippus, over the whole Holarctic range of these anchitherines. In this paper, size trends are described and interpreted against the background of simultaneous climatic change.
