Abstract

Recently, some planktic foraminifera were successfully retrieved from the shale unit of the Temburong Formation at the Paal River in the Tenom district, southwest Sabah. The area is underlain by the Crocker and Temburong Formations and overlain by alluvial deposits. The Temburong Formation is mainly composed of fine-grained flysch deposits, characterized by rhythmic repetitions of siltstone and shale. Two samples of shale were collected for micropaleontological analysis. The samples were processed according to standard micropaleontology method for foraminifera. A total of eleven species of planktic foraminifera have been identified. The planktic foraminifera comprise Catapsydrax dissimilis, Catapsydrax unicavus, Globigerina ciperoensis, Globigerina connecta, Globigerina eamesi, Globigerina praebulloides, Globigerinoides primordius, Globigerinoides triloba, Globoquadrina venezuelana, Globorotalia bella and Praeorbulina sicana. The planktic foraminifera can be divided into two assemblages representing two biozones namely the Globorotalia ciperoensis Zone (Zone P22) of Chattian age (Late Oligocene) and the Catapsydrax dissimilis-Preaorbulina sicana Zone (N7) of late Burdigalian (Late Early Miocene). The Temburong Formation was deposited at a distal part of a deep-sea fan.
