Permian and Early Triassic conodonts from Northwest Peninsular Malaysia

Abstract: Limestones exposed at Gunong Keriang, Kedah, have yielded conodonts representative of the Early Permian (Wolfcampian) Neogondolella bisselli-Sweetognathus whitei and the Early Triassic (Smithian) Neospathodus waageni Zones.

The Kodiang Limestone exposed at Bukit Hantu near Kodiang, Kedah has yielded conodonts representative of the Late Permian (Capitanian) Neogondolella rosenkrantzi-Neospathodus divergens Zone and species of Neospathodus characteristic of the Early Triassic. The Permian-Triassic boundary is for the first time recognised in exposed sections in Malaysia. Since the Kodiang Limestone is shown to extend down into the Permian it is considered probable that it is continuous with the underlying Chuping Limestone.

The Middle and Late Permian appear to be absent at Gunong Keriang, being cut out by an unconformity or non-sequence.
