7. Porth Nanven, Cornwall, UK
At Porth Nanven Beach in Cornwall, England, a multitude of boulders are lapped by waves. They lie strewn along the shoreline – but also sit high on the cliffs above. The boulders have a smooth oval shape, which has given rise to the nickname ‘Dinosaur Egg Beach’. If they were dinosaur eggs, they would have had to have come from many different species, because the dimensions of the rocks vary from over three feet long to about the size of a chicken’s egg.
