Recent archaeological discoveries in Malaysia, 1965: East Malaysia and Brunei
Tom Harrisson, writing in 1966, reports on a year of intensive archaeological fieldwork across Sarawak, Sabah, and Brunei, with the long-running Niah Cave project as its centrepiece. The article functions simultaneously as a progress report on the Niah excavation and as a broader argument for how helicopter-assisted reconnaissance was reshaping understanding of prehistoric settlement patterns in Borneo’s remote interior.
Summary
The article’s central argumentative thrust is methodological and interpretive rather than purely descriptive. Harrisson uses the 1965 season to demonstrate that the Niah Cave project—running since 1954—was reaching its terminal phase, with the West Mouth habitation deposit cleared to approximately 35,000 years before present, leaving only a small “very deep” section to bedrock. The completion of Lobang Angus as the last of the six Great Cave mouths to be excavated marked a significant milestone. Yet the more consequential intellectual contribution lies in what Harrisson calls the “checking” of Niah’s coastal, protein-rich context against the high interior: the deliberate decision to send parties into the Mersing Mountains of the Ulu Kakus, over 500 feet above sea level in dense rainforest, to test whether undisturbed limestone caves in such settings necessarily yield prehistoric remains.
The negative results from the Kakus are the article’s most important interpretive finding. Harrisson argues that the absence of stone-age evidence in the remote interior is itself significant, establishing that early human activity in western Borneo correlated with open fertile valleys, plateaux, swampy areas, and low-tree country rather than with the dense, unsettled highland forest. This coastal-interior dichotomy becomes a working framework for subsequent Bornean prehistory. The Sekaloh River work reinforces this pattern: the inland caves show a “much lower and later degree of human activity” compared with the seaward Great Cave and Painted Cave, with the richest neolithic burial phase dating to c. 1,180 B.C. and proto-historical use extending to c. 1650.
A secondary thread concerns the broader material culture of Borneo. The glass analysis programme at the Corning Glass Museum in New York, covering monochrome beads and bangles estimated between 600 and 1500 A.D. from Kota Batu, Brunei, and Sarawak river delta trade sites, introduces a range of trace elements (barium, antimony, cobalt, strontium, zircon, silver, zinc, boron, bismuth, vanadium) not previously reported in Malaysian glasses, complicating earlier source-attribution models. The megalithic work in West Sabah and south-west Sarawak, and the recovery of the nearly extinct papan turai “native writing” boards, round out a picture of a region where durable stone and wood are the only surviving traces of ancient human activity in a terrain and climate that destroys all other structural evidence.
Key Findings
- The Gan Kira fossil-oyster layer at Niah yielded a C-14 date of 36,900 ± 1,000 years (U.C.L.A., Dr. F. W. Libby’s laboratory), fitting existing data on late Pleistocene water levels and human activity at the site (p. 192).
- The West Mouth habitation deposit was cleared to the c. 35,000-year level; 65 whole burials were removed for physical anthropological study, along with the entire human contents of Jeregan Cave (p. 192).
- In the upper Sekaloh, 36 caves were visited by ground party; 12 held significant prehistoric materials, all but one completely removed due to quarrying threats. The neolithic burial phase is dated to c. 1,180 B.C. (± 240 years) by C-14 (pp. 192–193).
- The Mersing Mountains, Ulu Kakus (over 500 ft above sea level, in the 3,000+ ft range dividing the Third and Fourth Divisions) produced no positive evidence of stone-age frequentation—only proto-historical Punan burials—confirming that remote interior caves do not necessarily yield prehistoric remains (p. 193).
- Corning Glass Museum analyses of Bornean beads (estimated 600–1500 A.D.) detected trace elements including barium, antimony, cobalt, strontium, zircon, silver, zinc, boron, bismuth, and vanadium, not previously reported in Malaysian glasses, complicating earlier two-source models for early bead traffic (p. 196).
- A previously unrecognised earthenware ware decorated with subdermal turtle bones producing irregular waving designs was identified at Tapadong Cave (Sabah), Gomantong Caves near Sandakan, and possibly at Lobang Angus, Niah (p. 194).
Conclusion
Harrisson’s definitive historical takeaway is that the negative evidence from the remote Bornean interior is as archaeologically significant as positive finds: the absence of stone-age remains in high, dense-forest limestone caves demonstrates that early human settlement in western Borneo was fundamentally a coastal and lowland phenomenon, tied to protein-rich environments, and that the Niah sequence cannot simply be extrapolated inland. This finding, combined with the near-completion of the Great Cave excavation, positions the Niah project as a closed chapter whose interpretive framework now requires testing against the broader island context.
Context
- The article draws on primary fieldwork data, C-14 radiocarbon dates (U.C.L.A. and other laboratories), and instrumental glass analyses conducted at the Corning Glass Museum, New York, under Dr. H. Brill.
- Historiographically, the piece is notable for introducing helicopter reconnaissance (operated by the British Army’s Centre Brigade and Royal Tank Regiment) as a systematic archaeological method in Borneo, and for establishing the coastal-versus-interior settlement model that would structure subsequent Bornean prehistoric research.
