THE ARMORED TANK THE SIZE OF A CAR
Glyptodonts were 2-tonne armadillo relatives the size of a small car, wrapped in a domed shell of solid bone.
One of them, Doedicurus, carried a spiked club on its tail that could shatter the shell of a rival.
They grazed Ice Age South America alongside giant sloths and saber-tooths, too armored to fear almost anything.
A tank with a mace for a tail.
Best armor in prehistory: shell, spikes, or speed?
