The spherical stones that line New Zealand’s Moeraki Beach reach up to seven feet in diameter and have been compared to everything from the marbles of giants to colossal dinosaur eggs to half-submerged prehistoric turtles, ready to stand up and shake off the sand at any moment. They’re actually concretions, masses of compacted sediment formed below ground more than 50 million years ago. As the sand that surrounds them erodes, they seem to rise to the surface as if pushed up from the center of the earth. The stones are also found on Bowling Ball Beach in Mendocino, CA, as well as elsewhere in the U.S. and Canada and Russia.
