The Loire Valley formed the floor of a vast sea 90 million years ago. Over the millennia, sediment from the sea floor, comprising fossilized living organisms and sand particles, became compressed to form what is now known as Tuffeau stone. Today whilst walking the dogs in the vineyards we came across this sea urchin - imagine it's 90 million years old and this vineyard used to be the sea bed!!

INCROYABLE......
