Scientists have discovered the best-preserved nervous system in an ancient fossil.

Dating back 520 million years, the clawed spider-like fossil shows clear evidence of a brain and of nerve cords running through the creature's trunk.

The specimen now confirms that the ancestors of spiders and scorpions were related, but branched off more than half-a-billion years ago.
