Abstract

–Biological clues, particularly marine fossils in Holocene coastal deposits from Sam Roi Yod National Park, Prachuap Khiri Khan province, western Thailand were preserved. Detailed systematic biological description and coastal stratigraphy presenting in this paper were contributed to unveil the characteristics of sedimentary sequences in association with the history of marine transgression and regression. Sedimentary sequences and fossils reveal marine episodes that were deposited mostly under intertidal and estuarine conditions. Marine faunas indicate regression periods of the sea. The age of some marine faunas were determined using AMS method and given the range of their deposition about 4,000 to 2,000 years BP. Results of dating confirm precise period of rapid marine gradual regression after the mid Holocene.
