| 摘 要： | Jurassic deposits of the Malayan Peninsula (Thailand) are stratigraphically limited to Toarcian and Aalenian only (Meesook & Sha, 2010, and literature cited therein). These are represented by wide spectrum of both clastic and carbonate rocks with full develop-ment of transitional ones. In the middle part of penin-sula (vicinity of Krabi) distribution of Jurassic facies suggest occurrence of full marine palaeoenvironments in NE part of it with gentle transition by lagoonal (brackish?) and tidal environments up to terrestrial ones in the SW part of peninsula. Sections studied, close to Thung Song city, are represented by 20 m thick sequence of thin-bedded limestones and marls of the Khlong Min Formation, most probably lagoonal palaeoenvironments (transitional = restricted ma-rine-brackish), indicated by specific benthic fauna dominated by different kind of ethological group of bivalves – infaunal, epifaunal and encrusted (epibion-tic) species like Protocardia, Praemytilus, Modiolus, Myrene, and Actinostreon. Very characteristic is a lack of full marine, stenohaline, other invertebrates – brachiopods, crinoids, echinoids etc.
