3 - Woolly Mammoth
If there is one animal most associated with the Ice Age, it has to be the woolly mammoth, that giant shaggy beast with long ivory tusks curling up from its massive trunk-like nose. The woolly mammoth was one of several species of mammoth, the earliest of which were probably small and amphibious creatures living in North Africa until about three million years ago. Their descendants eventually dispersed throughout Eurasia and the woolly mammoth, one of the smaller mammoth species, migrated to North America across the Bering Land Bridge sometime during late Pleistocene. Alas, this enigmatic creature did not survive long in the New World. The last of the woolly mammoths died out at the end of the last ice age, about ten thousand years ago.
