To date, West Malaysia (Peninsular Malaysia) has recorded more than 100 prehistoric sites. The archaeological record demonstrates that early humans arrived in this region beginning in the mid-Palaeolithic. While the Lenggong Valley possesses a long history of human occupation spanning the last 200,000 years, archaeological investigations in Upper Kelantan and Upper Pahang, on the other hand, have suggested that these areas were occupied by early humans throughout the Late Pleistocene-Holocene period (10,000-1,500 ya). With a special focus on the lithic assemblages recovered from Gua Sagu and Gua Tenggek in Pahang (14,000 ya), this project explores the behavioural signatures and palaeo-economy of the early humans of Malaysia through an in-depth investigation of the lithic reduction technology adopted by the Palaeolithic and Neolithic communities in Malaysia. The results shows that the lithic technology of Gua Sagu and Gua Tenggek included freehand percussion and bipolar percussion/splitting. On another note, these studies also suggested that the reduction technology of Gua Sagu and Gua Tenggek is similar to that identified at the early modern human site of Kota Tampan (ca. 70 ya) in Lenggong Valley, further indicating continuity of lithic tradition from the middle Palaeolithic to the late Palaeolithic in West Malaysia.
