An ancient sea scorpion - bigger than a human
Scientists have found the fossilised claw of a 2.5 metre long sea scorpion, a nighmarish creature living before the age of dinosaurs.
German scientist Markus Poschmann, who found the claw in a quarry around 15 years ago, says scientists didn't previously know that these prehistoric animals were so big.
