All taxa are new records of ammonoids in Thailand. They comprise the Devonian ammonnoid ?Parawocklumeriidae gen. et sp. indet., the Carboniferous form Goniatites cf. eganensis Korn and Titus, 2011, the Permian ammonoid Cyclolobus sp. indet. from Satun province, on the western part of the peninsula, and the Triassic ammonoid Ceratitina gen. et sp. indet. from Phatthalung province, on the eastern part of the peninsula. Key words: new records, ammonoids, Cephalopoda, peninsular Thailand. INTRODUCTION IURP .RK 0DSUDR R൶FLDOO\ .R 3UDR Phuket province.
