Man-sized Sea Scorpion claw found

Scientists have discovered an immense fossilized claw of an 8-foot sea scorpion. The 390-million-year-old specimen was found in a German quarry.

The creature, which has been named Jaekelopterus rhenaniae, would have paddled in a river or swamp. The size of the beast suggests that spiders, insects, crabs and similar creatures were much larger in the past than previously thought.

The eurypterids (sea scorpions) are believed to be the extinct aquatic ancestors of modern land scorpions and possibly all arachnids (the class of animals that also includes spiders).
