* The woolly mammoth: This massive mammal was widespread in the northern hemisphere during the last ice age. Although the woolly mammoth itself is extinct, its closest living relative is the Asian elephant.
* The saber-toothed tiger: This ferocious predator was also found throughout the northern hemisphere during the ice age. The saber-toothed tiger is extinct, but its closest living relatives are the modern-day lions, tigers, and jaguars.
* The giant ground sloth: This herbivore was found in South America during the ice age. The giant ground sloth is extinct, but its closest living relatives are the modern-day sloths.
* The Irish elk: This gigantic deer species once roamed the forests of Europe and Asia during the ice age. The Irish elk is extinct, but its closest living relatives are the modern-day red deer and elk.
* The aurochs: This large wild cattle species was found in Europe, Asia, and North Africa during the ice age. The aurochs is extinct, but its closest living relative is the domestic cow.
