Situated about 20 kilometers west from the provincial capital and near Laem Pho Village, Susaan Hoi is one of the most exceptional natural phenomena and archaeological finds you may ever see. During the Tertiary era or around 75 million years ago, the place was once a huge freshwater swamp, inhabited by particular diverse snail species. The swamp was entirely filled with snails and layer upon layer of snails built up the swamp floor. In the long run, due to the changes in weather and the surface of the Earth, seawater flooded the area and wiped out the swamp; the snail shells were enveloped with limestone elements from the sea and what’s left are layers of fossilized shells known as Shelley Limestone. It left about 40 centimeters thick of fossilized shell over 10 centimeters of lignite rock. Further geographic upheaval caused the spreading of these impressive broken layers around the shore of Laem Cape.
Literally meaning ‘shell cemetery’, Susaan Hoi is best observed during low tides to further appreciate the number of fossilized remains. [Read more…]
