The fossilised remains of a giant claw that once belonged to a sea scorpion roughly 2.5 metres long have been found in Germany.
Researchers say the massive creature is the largest arthropod ever known, and it is 30 centimetres bigger than the previous largest specimen of the same species.
The University of Bristol, UK examined the claw which measured 46-centimetre-long, and believe it belonged to a sea scorpion species called Jaekelopterus rhenaniae that roamed the ocean floors some 390 million years ago. The claw was found in a quarry in western Germany.
J. rhenaniae belongs to a category of animals known as arthropods, distinguished by traits such as a segmented body and an exoskeleton, which includes modern species such as spiders and horseshoe crabs.
