What is the historical range of saiga antelopes?
The saiga antelopes ranged from as far west as modern-day England and France to as far east as northern Siberia, Alaska, and probably Canada before the Holocene. During the Pleistocene epoch, they also occurred in Beringian North America and the British Isles. Today, the dominant subspecies of the saiga antelope is only found in one region in Russia and three areas in Kazakhstan, and the Mongolian subspecies is found only in western Mongolia. Saigas are now extinct in China, Ukraine, and southwestern Mongolia.
