If there is one animal that could be considered the living (or, ah, once-living) emblem of the Ice Age, that animal is undoubtedly the woolly mammoth. But second place is nothing to sneeze at, and second place is firmly defended by a pair of 20-centimetre-long canine teeth. Yes, in the popular imagination, the second-most iconic animal of the Ice Age is the ferocious sabretooth tiger.

It's rather shame that there's not really such a creature as a sabretooth tiger.
