Europe (Mio-Pleistocene)

During the Mio-Pleistocene, Europe has gotten colder, but animals are relatively unchanged by this, also many animals have increased populations or were bred from domesticated animals to be identical to it's extinct ancestors.

European Prairie
A grassland that is full with many megafauna.

Mammals
