Over the past fifty years,Numerous fossils have been discovered in Thailand and especially during the last decade. Some of the earliest reports of fossils in Thailand in 1916 on trilobites from the Carboniferous Period in Phatthalung Province in the South in 1920. The known fossil record in Thailand ranges from Cambrian trilobites up to Holocene pollen. Although these fossils are considered part of the national heritage, many of them face multitudinous threats. Numerous fossils have been damaged and the sites destroyed during the process of mining lignite, sand, limestone, and other economically important rocks. Additional fossils have ended up in private collections both locally and overseas.
