One big bug.
This ancient creepy-crawly was very different from today's land-dwelling scorpions. With short legs and a broad tail fin instead of a stinger, it likely lived only underwater, says O. Erik Tetlie, a geologist at Yale University in Connecticut. The scorpion's fearsome claw probably made it a top ocean predator. But once large fish like sharks evolved, they may have hunted the sea scorpions to extinction.
