520 million year old fossil had nervous system

Big clawed fossil had spider-like brain
By Melissa Hogenboom Science reporter, BBC News
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.

Ancient  creatures may have been more evolved than first thought.If cryptids are ancient creatures still around today, they may be more sophisticated than we imagined .
