is located at Ban Laem Pho, 17 kms from downtown Krabi along the route to Hat Noppharat Thara.  Long ago this was a freshwater marsh populated by clams and other bi-valves, chiefly little two centimeters long "Hoi Khom" or pond snails, which grouped and multiplied in such numbers that the dead formed a floor for the living.  This process, repeated over eons, led to the creation of layer of fossils about 40 cms thick, called shelly limestone.  Scientific test have established that the age of these fossils is about 40 million years.  Minibuses leave the town for the Fossil Shell Beach daily from 6.00-17.00 hrs.
