Lower and Middle Triassic conodonts from the Jerus Limestone, Pahang, Peninsular Malaysia

Abstract

The Jerus Limestone, Cheroh, Pahang, previously considered part of the Raub Group and of Carboniferous or Permian age, has yielded rich conodont faunas of Lower Triassic (late Dienerian) and Middle Triassic age. The Lower Triassic, until recently unrecognised in western Pahang, appears to be predominantly of carbonate facies, including channel filling conglomeratic limestones derived from nearby active fault scarps.
