Fossil Shell Beach Krabi (Susan Hoi)

This guide to Fossil Shell Beach in Krabi walks the limestone slabs that crack open along the tideline to reveal millions of fossilized freshwater snail shells, cemented together some forty million years ago when this stretch of coast was still a freshwater swamp. It traces how the beach became a tourist stop, with food carts once feeding busloads of visitors along the shore, and introduces the vendors who still work a handful of stalls here. Guides say this shell limestone turns up in only two other spots on Earth.
