Abstract

Some 13 species of Middle Triassic ammonoid fossils were discovered from two outcrops of sedimentary rocks belonging to the Telong Formation. The outcrops are located within the Felda Aring 5, along the road connecting Gua Musang Town and Kuala Berang. These two localities contained two ammonoid assemblages that are correlatable with the Standard Ammonoid Zone of the Tethyan region. Locality QZ480 contains four ammonoid species i.e. Balatonites cf. B. balatonicus, Danubites kansa, Kellnerites samneuensis, Hollandites sp. and Acrocordiceras sp., while locality QZ467 contains eight species i.e. Frankites regoledanus, Frankites apertus, Celtites epolensis, Clionitites sp., Protrachyceras costulatum, Anolcites sp., Joannites sp. and Megaphyllites jarbas. Biostratigraphically, ammonoid assemblage of locality QZ480 characterize the middle Anisian Balatonicus Subzone of Balatonites Zone while those of locality QZ467 characterize the late Ladinian Regoledanus Subzone of Protrachyceras Zone. Based on correlation, the results support the idea that the study area which can be correlated to the Triassic Lampang-Phrae Basin located on the Sukhorthai Terrain of Shan-Thai Block, belonging to the Cathaysian domain. The ammonoid assemblages pose a high scientific heritage value, particularly in their role as good age indicators for the Triassic.
