Abstract:
Cave sediments exceptionally rich with numerous vertebrate dental remains have been discovered in Merapoh, Pahang. To date, a total of 611 isolated teeth
have been collected, consisting of the following taxa: Hystricid, Rhizomys spp. (?), Helarctos malayanus, Ursus thibetanus , Neofelis nebuloso, Canid (?), Sus spp., Cervus unicolor, medium-sized Cervids, Tragulus spp., Capricornis sumatraensis, large-sized Bovids, Rhinocerotid, Cercopithecines and Colobines, Pongo sp. and possibly other higher primates. The faunal assemblage resembles those discovered in western Peninsular Malaysia that have been dated from 33-500ky (thousand years). Cave morphology shows the fissure filled with the sediments could have been part of a subterranean stream. The absence of bones may indicate that most of the fossils have gone through a long history of reworking and other taphonomic processes, and only the most resistant dental remains have been preserved.

Abstrak: Enapan
gua yang kaya dengan pelbagai tinggalan gigi haiwan vertebrata telah ditemui di Merapoh, Pahang. Sehingga kini, 611 gigi individu telah dikutip, terdiri dari
taxa berikut: Hystricid, Rhizomys spp. (?), Helarctos malayanus, Ursus thibetanus , Neofelis nebuloso, Canid (?), Sus spp., Cervus unicolor, Cervids bersaiz sederhana, Tragulus spp., Capricornis sumatraensis, Bovids bersaiz besar, Rhinocerotid, Cercopithecines dan Colobines, Pongo sp. dan kemungkinan primat yang lebih tinggi. Kumpulan fauna ini menyerupai kumpulan yang dijumpai di barat Semenanjung Malaysia yang telah ditentukan umur pada 33-500 ribu tahun. Morfologi gua menunjukkan fisur yang diisi dengan enapan mungkin adalah sebahagian dari aliran air bawah tanah. Ketiadaan tulang menunjukkan kebanyakkan fosil telah mengalami sejarah kerja semula dan proses tafonomi yang lain sehingga hanya tinggalan gigi yang paling tinggi ketahanan terpelihara.
