Article: Triassic conodonts from Sumatra
I. Metcalfe, T. Koike, M. B. Rafek and N. S. Haile
Conodonts are for the first time recorded from Sumatra. Limestones near Prapat, Lake Toba, northern Sumatra have yielded conodont faunas characteristic of the Late Carnian Metapolygnathus polygnathiformis conodont zone. Limestones in the Sawahlunto area of central Sumatra have also yielded probable Late Triassic conodonts.
