Prehistoric Fishing at Bukit Tengkorak, East Coast of Borneo Island Rintaro Ono 1 ABSTRACT Fish bones excavated from a Neolithic site, Bukit Tengkorak. on the east coast of Borneo Island were analysed. Twenty-eight taxa of marine fish were identified, including Elasmobranchii and the families Scaridae, Labridae, Lethrinidae, Serraoidae, Lutjanidae, Balistidae, Sigaoidae, Haemulidae and Diodontidae, with only a few occurrences of pelagic fish such as Scombridae, Caraogidae and Sphyraenidae. Observations of local Bajau fishing activities near the site revealed that most were carried out inside the coral reef, and that the major fishing methods were netting and line fishing. Ethnographic information on traditional Bajau fishing patterns indicates the same tendency. These results suggest the importance of netting and line fishing and the lesser importance of pelagic trolling in the subsistence of the prehistoric Bukit Tengkorak people io Neolithic limes. Keywords: BORNEO ISLAND, BUKIT TENGKORAK, FISH BONE ANALYSIS, PREHISTORIC FISHING STRATEGIES. INTRODUCTION Fishing was an important aspect of subsistence in many communities in the Pacific and Island Southeast Asia. However, archaeological analysis of fish remains in Island Southeast Asia bas been very limited compared with the Pacific region. This paper presents the results of the analysis of a substantial collection of fish bones from Bukit Tengkorak, a Neolithic site in Sempoma district, east coast of Borneo Island, and compares them with modem fish specimens collected near the site. The traditional use of marine resources by Bajau people who live in the Semporna region was also studied as a basis for interpreting the prehistoric fishing done by the Neolithic people who lived in the same area. The study focuses on the major fish caught, the variety of fish used in subsistence, and the catching technology. Cultural continuity and changes in fishing in east Borneo since Neolithic times are discussed from these points of view. As part of my study, about 200 specimens of modem fish were collected to permit identification of the archaeological bones. This was especially important as adequate reference material is lacking from Island Southeast Asia. BUKIT TENGKORAK ROCK SHELTER The Bukit Tengkorak site is a complex of rock shelters at the south-eastern end of Sempoma Peninsula on the east coast of Sabah, Borneo Island (Fig. l) . The site is located at the summit of a low coastal bill at around 150 m above sea level. Archaeological 1 National Museum of Ethnology, Senro Expo Park, Suit.a, Osaka 565-85 l l , Japan.

The total area excavated was 10.5 m2• Seven trenches of 1 x 1 m and one of 0.5 x 0.5 m were excavated in the southern side of the rock shelter complex in 1987, 1994 and 1995, and three trenches of 1 x 1 m in the northern side in 2001 (Fig. 2). Both areas were excavated through 30 spits to a depth of almost 150 cm (1 spit= 5 cm). In both parts of the rock shelter complex, seven to eight stratigraphic layers were recognised. In the southern part, Layers 1 and 2 are the disturbed top layers. Layers 3 to 6 are composed of blackish to brownish organic soil. Layers 7 and 8. composed of ashy or brownish soil, possibly belong to the Neolithic age on the basis of their radiocarbon dates and excavated artefacts (Chia 1997). In the northern part, Layer 1 is the disturbed topsoil (sandy: lOYR 4 .0/2.0). Layers 2 to 6, composed of blackish to brownish organic soil (lOYR 2.0/1.0 to 7.5YR 3.0/ 2.0), are late to early Neolithic layers. Layers 7 and 8, the lowest light to dark reddish clay layers (2.5YR 3.0/3.0 to 5.0YR 4.0/5.0), produced no artefacts except some chert tools and chips, and certainly do not belong to the Neolithic age (Ono 200la). These excavations unearthed a quantity of potsherds and stone tools, including obsidian tools, and abundant fauna! remains, especially fish bones and marine shells. Most of the radiocarbon dates obtained during the research clustered around 1400 to 500 BC (Table 1)2 . ~·· Semporna P e ninsula South China Se:i :· :: ·.·.·.. .... \ : ., Figure 1: Location of the study area and the Bukit Tengkorak site. 2 As Table 1 shows, most of the radiocarbon dates from the middle to lower layers in both southern and northern shelters at Bukit Tengkorak ranged from about 800 to 1400 BC, except for one date of about 4000 BC from Layer 8 in Trench G 17 in the southern rock shelter complex. 79 Ono: Prehistoric fishing at Bukit Tengkorak o.

The analysis of excavated obsidian tools and chips by Bellwood (Bellwood and Koon 1989) and also by Chia (1997, 2001) revealed that some of them originated in Talasea in New Britain, which is about 5,000 km away from Bukit Tengkorak. This suggests that the site may have bad an important relationship with the Lapila cultural complex in Melanesia3. 3 In Chia's study, 30 of the 552 excavated obsidian pieces were analysed by Cameca MBX electron microprobe. The analysis was conducted by Robert Tykot and revealed four different and distinct compositional groups of obsidian in Bukit Tengkorak. The largest compositional group, which came mainly from middle LO upper layers, matches very well with the Kutau/Bao obsidian source in Talasea, while another group, which mainly came from the lower layer, matches obsidian from Talaud Island, Indonesia. for which no geological source bas yet been determined. The other two groups (only one piece in each) did not match up with any of 66 known obsidian sources in the Pacific and South East Asian regions (Chia 1997). During 1994 to 1995, a search for a local source of obsidian 80 NEW ZEALAND JOURNAL OF ARCHAEOLOGY TABLE 1 RADIOCARBON DATES FROM BUKIT TENGKORAK Lab Number ANU 5773 ANU 5772 BETA 74447 ANU 5771 ANU 6544 ANU 5770 ANU 5768 ANU 5769 BETA 156152 BETA 74448 BETA 156147 BETA 156152 BETA 83783 BETA 83784 BETA 156148 BETA 83705 Date (BP) 145.2±2.5 138.4±4.8 101.0±0.6 1050±500 2870±80 2330±170 2320±250 2700±110 2890±70 3190±60 2780±40 2860±40 2940±50 2650±90 3040±40 5330±80 Trench/depth Material Cal age 032/0-5 cm charcoal charcoal 032/45-50 cm charcoal 017/15-20 cm charcoal AD 530-1400 032140-45 cm shell 550-400 BC 0321surface charcoal 764-199 BC 032/30-35 cm charcoal 800-100 BC 033n0-75 cm charcoal 1000-800 BC 03210-5 cm shell 1380-990 BC Cl/20-25 cm shell 1190-860 BC Gl 7/50-55 cm charcoal 940-810 BC F3n0-75 cm charcoal 1060-880 BC 03/65-70 cm charcoal 1285- 990 BC Gl7n0-75 cm charcoal 980-745 BC Gl7/95-100 cm charcoal 1360-1360 BC F3/100-105 cm charcoal 4340-3975 BC Gl 7/125-130cm Reference Bellwood 1988 Bellwood 1988 Chia 1997 Bell wood 1988 Bellwood 1988 Bellwood 1988 Bellwood 1988 Bellwood 1988 Ono 200la Chia 1997 Ono 200la Ono 200la Chia 1997 Chia 1997 Ono 200la Chia 1997 The material excavated from the southern rock shelter complex in 1987, 1994 and 1995 was sieved through 5 nun mesh. Smaller meshes were tried on the material excavated in 2001 but were not effective, because of the wetness and stickiness of the excavated soil. Consequently, only 5 mm mesh was used, the same as in the earlier research, because no water source was available for wet sieving at the sununit of the hill.4 Not all the faunal materials from the 1987 excavation have yet been identified5. Shells, mammal and reptile bones recovered from the southern rock shelter complex in 1994 and 1995 were counted and identified by Chia and Davison (Chia 1997). However, most of the fish remains were not identified in detail because of the complete lack of comparative modern fish bone specimens in Malaysia at the time of the analysis. Of the faunal material, including shells, recovered from the northern rock shelter in 2001, only the fish remains are presented in this paper. Unfortunately, only a few artefacts identified as possible fishing tools were recovered in 1987. Three pieces of worked shell were tentatively identified as parts of fishhooks and one as part of a trolling lure shank by Bellwood (Bellwood 1989). However, these artefacts were around Bukit Tengkorak was conducted, but no source was found. 4 For further analysis, 100 g of U1e excavated soil was collected from each spit of three trenches for water sieving through l.O mm mesh at the laboratory. All samples have been sieved but identification of sieved fish remains bas not yet been completed. Here, I mention only U1e average number of identifiable fish bones in each spit of Trench D3, which was about 50. s On the basis of the radiocarbon dates obtained (Bellwood 1989) and Cbia's survey, it was suggested that the area excavated in 1987 was possibly disturbed and might not have yielded an accurate sequence (Chia 1997). For these reasons, I did not include the fish remains excavated in 1987 in my analysis. Ono: Prehistoric fishing at Bukit Tengkorak 81 not complete and could not be confirmed as fishing tools. No artefacts related to fishing were excavated in 1994, 1995 and 2001. This situation might be due to the location of the site, which is on the summit of the bill. The manufacturing site might be somewhere on the coast or at the foot of the hill, although no archaeological sites have been found or excavated in the low land area around Bukit Tengkorak so far. METHOD OF ANALYSIS OF FISH REMAINS At the beginning of this study, about 200 specimens (38 families/90 species) of modern fish were collected for use in identification (Table 2). Most were collected in Semporna where the site is located, although some were collected in other towns in Sabah. They were identified by the author and staff of Sabal1 Museum during the survey using reference books (Masuda and Allen 1991; Okamura and Amaoka 1997; Allen 1998). Nomenclature and taxonomy follow Allen (1998). Cranial elements, special elements, vertebrae and teeth were used for identification in the first stage of the analysis. The cranial elements were maxilla, premaxilla, dentary, articular, quadrate, pharyngeal clusters, opercular, preopercular, byomandibular, palatine, cleithrum, post-temporal, scapula, and supracleithrum; special elements included the first spine of trigger fishes (Balistidae) and spines of porcupine fishes (Diodontidae). The use of gill elements such as cleithrum, post-temporal, scapula and supracleithrum was more limited than the use of mouthparts such as maxilla, premaxilla, dentary and articular6 . In this first stage of the analysis, vertebrae were used only to distinguish bony fish (Teleostomi) and cartilaginous fish (Elasmobranchii). Teeth were used to identify trigger fishes and distinguish cartilaginous fish from bony fish. In the second stage of the analysis, identification by vertebrae was carried out on some fish remains. Thoracic, precaudal, caudal and ultimate vertebrae were used. The aims of this second stage of analysis were (l) to determine bow many taxa could be added by using vertebrae for identification; (2) to ascertain how much the total NISP and MNI were increased as the result of analysis of vertebrae; and (3) to judge the effectiveness of using vertebrae for identification. For the purpose of analysis, an assemblage was defined as the contents of any single excavation trench. Thus all bones from one excavation trench and one excavation level (layer/spit) were designated as an assemblage. Following the method of Leach (1986), each assemblage was sorted into identifiable and not identifiable piles, and all materials were rebagged, then identifiable fragments were sorted anatomically and re-bagged again. Taking each part of the anatomy in tum, bones were sorted into species, genera, and families. and identified with reference to the comparative collections. The Minimum Number of Individuals (MNI) and also Number of Identified Specimens (NISP) are calculated with reference to this assemblage unit. The calculation of MN1 basically follows the general technique of Chaplin (1971), although size mismatches were also take n into account when counting major cranial elements such as premaxilla, dentary, maxilla, articular, quadrate and pharyngeal clusters. 6 For example, the cleitbrum could be used only for the identification of Siganidae spp., and the scapula was used only for double head parrotfish (Bolbometopon spp.), because of their diagnostic characteristics in these families and the fragility of these elements. 82 NEW ZEALAND JOURNAL OF ARCHAEOLOGY TABLE 2 THE MODERN COMPARATIVE FISH COLLECTION ? =name not yet collected Family Belonidae Haemulidae Hemiramphidae Serranidae Carangidae Lutjanidae Lethrinidae Mullidae Scaridae Labridae Ephippidae Siganidae Acantburidae Sphyraenidae Scombridae Balistidae Ostraciidae Tetraodontidae Diodontidae Nemipteridae Muraenidae Menidae Caesionidae Elopidae Sparidae Holocentridae Mugilidae Platycephalidae Plotosidae Kyphosidae Ariidae Pomacanthidae Psettodidae Malacanthidae Dasyatididae Myliobatidae Carcharhinidae TOTAL Local name selo kaci togen kerapu ikan putih ikan merah ketambak tin bu nan ogos/batu bukan bunaq bawis kumay Iengo ikan kayu tombat buntal buntal buntal duri kerisi tago salap selap sulig ? ? ketong brenang ? batik ilap barukang ? ? ? pahi pahi manok kalitan No. of species 2 Total Specimens 2 4 1 7 3 15 9 5 14 4 3 5 7 2 3 4 2 4 3 1 l l 2 1 1 1 2 1 l 9 21 10 4 11 10 3 5 4 2 10 4 1 l 3 3 2 2 2 2 2 2 4 2 l 1 2 2 90 l 2 2 1 2 l 1 1 158 Ono: Prehistoric fishing at Bukit Tengkorak 83 In searching for any changes through time and space, it is us ually found desirable to combine the basic results into totals by family, rather than at the taxonomic levels identified and recorded (Leach 1986). In this report, tables present infonnation only at family level. RESULTS OF THE FIRST STAGE OF ANALYSIS In both the southern and northern parts of the rock shelter complex, 25 of the 30 excavated spits contained fish bones. Fish remains from three of the nine trenches have been identified and are presented here. The nwnber of faunal remains from other trenches is smaller7 . These three trenches were Trench J 19 and G 17 in Ule sou them rock shelter complex and Trench 03 in the northern rock shelter. Identification was carried o ut by spit level at first and combined into layers for the purpose of identifying significant changes though time. No fish bones were recovered from Layers 7 and 8 in either the southern or northern rock shelters, and the analysis is therefore confined to Layers l to 6 for all three trenches. A total of 22,071 pieces of fish bone were counted from these three trenches. Identified bones numbered 4,086 and recognisable elements numbered 11 ,180. This means that about 19% of the total bones were identified and 50% of them were recognisable as elements. The other 50% were mostly very small fragments, which cannot so far be identified or recognised. Table 3 shows the numbers of each anatomical part identified in each trench. The major anatomical elements apart from vertebrae were (1) premaxilla, (2) dentary, (3) quadrate, (4) maxilla, (5) articular and (6) pharyngeal clustef!. Twenty taxa were identified during the first stage of the analysis (Fig. 3). Parrotfish are the most abundant, followed by wrasses, groupers and emperors (by MNI). The numbers of identified bones of pelagic fish such as barracudas and jacks were very small, and no tunas were identified. Tables 4 to 6 show the MNI and NISP of each family in each of the six occupatio n layers in each trench. There are significant differences in temporal variation and distributio n between Trench 03 in the northern rock shelter and Trenches J19 and Gl7 in the southern rock shelter complex. The major difference is in the amount of fish remains in the upper layer and the middle to lower layers at each rock shelter. In Trench 03, a very small number was recovered from the upper layer and tl1e nwnber was larger in the middle to lower layers (Fig. 4 top). However, the tendency in Trenches J 19 and G 17 was the exact opposite. The largest numbers of fish remains were produced from the upper layers and fewer from the lower layers (Fig. 4 middle). 7 Three trenches in the southern rock shelter complex produced no fish remains (Chia 1997), and trench C 1 in the northern rock shelter produced fewer than 20 pieces of fish bone. One trench in the southern rock shelter complex produced about 600 pieces of fish bone and one in the northern rock shelter 250. However, these numbers are still much smaller than those from the three trenches selected for analysis and reported in this paper. 8 However, if the vertebra is included as an identifiable anatomical element, it is the most abundant. NEW ZEALAND JOURNAL OF ARCHAEOLOGY 84 As mentioned before, lhe upper layers, especially layers 1 and 2, were disturbed. This means lhat about 30% of fish remains from Trench 119 and Gl7 came from the disturbed layer, although the olher 70% were from Layers 2 and 3, which were estimated to date around 1000 BC. The exact date of the disturbed layers bas not yet been ascertained, although according to the sequence in Trench 03, they might have been deposited around 500-1000 BC, in Neolithic times. In contrast to lhe sequences in Trenches 119 and Gl7, the numbers of fish remains in Trench 03 increased abruptly from Layer 3 to Layer 5, all of which are estimated to belong Neolithic times around 800-1400 BC9 .

Lastly, Figure 4 (bottom) shows the temporal distribution of the major fish families in the whole of the Bukit Tengkorak site. The numbers of each taxon tend to be larger in Layers 2 to 5, especially Layers 2 and 3, while the numbers in Layers l and 6 are generally small. This suggests that all the major fish could be caught from early to late Neolithic by the people in Bukit Tengkorak, but the intensity of fishing activity was greater during the middle Neolithic time, dated around 1000-800 BC. 00 OI TABLE 4 MNI (NISP) OF FISH FAMIUES IN TRENCH Jl9 Family Scaridae Labridae Serranidae Lethrinidae Lutjanidae Balistidae Haemulidae Diodontidae Sparidae Pomacanthidae Siganidae Muraenidae Nemipteridae sub-total Mullidae Platycephalidae sub-total Ariidae Mugilidae Carangidae Elasmobranchii sub-total Total Habitat reef, rock reef botlOm reef, sand bottom reef, reef edge reef, reef edge shallow to 40 m reef, reef edge shallow to 50 m shallow to 30 m reef, reef edge reef, rock shallow to 50 m reef bottom Layer 1 15(29) 6(9) 3(4) 2(3) 1(3) 4(9) 0(0) 1(1) 0(0) 0(0) 0(0) 0(0) 0(0) Layer 2 34(133) 29(70) 18(107) 19(65) 12(35) 8(22) 5(15) 2(6) 3(4) 2(3) 2(6) 1(2) 1( 1) Layer 3 27(76) 24(38) 13(18) 11(13) 12( 14) 5(10) 7(4) 4(7) 6(11) 2(2) 0(0) 1(2) 0(0) Layer 4 24(53) 21(32) 15(31) 10(19) 3(3) 3(7) 5(12) 3(13) 1(1 ) 1(1) I (I) 0(0) 0(0) Layer 5 7(11) 1(1) 6(18) 6(6) 1(1) 2(2) 0(0) 3(4) 0(0) 2(2) 0(0) 0(0) 0(0) Layer 6 4(6) 2(2) 3(8) 2(2) 2(2) 1(1) 1(1) 2(2) 1(1) 0(0) 0(0) 0(0) 0(0) - 32(58) 0(0) 0(0) 0(0) 0(0) 0(0) 0(0) 4(4) 135(468) 1(1) 1(1) 2(2) 2(2) 0(0) 2(2) 15(15) 19(19) 112(189) 0(0) 0(0) 0(0) 0(0) 1(I) 0(0) 7(12) 8(13) 87(173) 0(0) 0(0) 0(0) 0(0) 0(0) 0(0) 9(9) 9(9) 28(45) 0(0) 0(0) 0(0) 0(0) 0(0) 0(0) 1(1 ) 1(1) 18(25) 0(0) 0(0) 0(0) 0(0) 0(0) 0(0) 1(1) 1(1) 36(62) 156(485) 120(197) 96(182) 29(46) 19(26) sand bottom sand bouom reef-estuarine inner bay coastal sea coastal sea - . 4(4) Total 111 (308) 83( 152) 58(186) 50(108) 31(52) 23(5 1) 18(32) 15(33) 11(17) 7(8) 3(7) 2(4) 1(1 ) 41 3(959) 1(1) 1(1) 2(2) 2(2) 1(1) 2(2) 37(42) 42(47) 457(1006) % 24.2(30.7) 18.1(15.1) 12.6(18.5) 10.9(10.7) 6.7(5.1) 5.0(5.0) 3.9(3.2) 3.2(3.2) 2.4(1.7) 1.5(0.8) 0.6(0.7) 0.4(0.4) 0.2(0.l ) 90.3(95.6) 0.2(0.l) 0.2(0.l) 0.4(0.2) 0.4(0.2) 0.2(0.l) 0.4(0.2) 8.0(3.7) 9.1(4.2) 100 z l!1 ~ ~ > z 0 ~ 0 c:: ~ > t"" 0 "" > :ii::!

Of 1,611 vertebrae in Trench D3, 1,099 (68.2%) could be identified at least to family level; of 624 vertebrae in Trench 119, 467 (74.8%) could be identified. The slightly higher proportion in Trench J 19 might be because the total number of vertebrae was smaller than in Trench D3. In Trench D3, total NISP increased dramatically, from 2,087 to 3,224, an increase of about 60%, and six new taxa were identified (Table 7). These were surgeon fishes (Acanthuridae), fusiliers (Caesionidae), jacks or trevallies (Carangidae), longtoms (Belonidae), archer fishes (Epbippidae) and tunas (Scombridae). Among these newly identified taxa, surgeonfishes were most numerous and ranked as the twelfth largest of the 28 taxa in Trench D3. In Trench Jl9, the total NISP increased from 1,006 to 1,497, an increase of about 50%, although only one taxon, surgeon fishes (Acanthuridae), was newly identified (Table 8). The total MNI in Trench D3 increased from 716 to 880, an increase of about 25%, and that in Trench Jl9 increased from 457 to 571, an increase of about 23%. These results strongly suggest the importance of vertebrae for identification of fish remains, if the total number and proportion of vertebrae are relatively high among all identifiable elements. At Bukit Tengkorat, the use of vertebrae increased NISP by about 50 to 60% and MNI by about 25%. The use of vertebrae can also increase the total number of taxa, adding at least one to six taxa in Bukit Tengkorak. Even when vertebrae were used for analysis, however, few pelagic fish, especially tunas, were found in the fish remains from Bukit Tengkorak. Most of the bones of parrotfish, wrasses, and other big fish such as groupers, emperors and snappers from the southern rock shelter tend to be bigger than those in the northern rock shelter10 . On the other hand, of the smaller fish, the proportion of rabbit fishes (Siganidae) was much higher in Trench D3, and the proportions of other identified small fish such as goat fishes (Mullidae) and breams (Nemipteridae) were also higher in Trench D3 compared with those in Trench 119 and Gl7. Moreover, the bones of the six newly identified taxa in Trench D3 were also small, even including tunas (Scombridae). The number of identified fish remains in Trench D3 was 2,037 without vertebrae and 3,224 with vertebrae; t11e number of identifiable elements was 6,661 witl1out vertebrae and 7,751 with vertebrae, out of a grand total of 14,758 pieces from this trench. This means that without vertebrae, about 14% of tl1e total fish remains were identified at least to family level, and about 30% of all recognised elements were used for identification. When vertebrae were used, the proportions increased to 22% and 52% respectively. 10 The soil of tl1e upper layers in the southern rock shelter complex generally ranges from pH 7.0 to 6.5, and in the lower layer ranges from pH 6.5 to 6.0. Similarly, the soil of the upper layer in the northern rock shelter ranges from pH 6.8 to 6.5, and that of lower layers from pH 6.5 to 6.0 . This suggests that the differences in size of excavated fish remains between the southern and northern rock shelters may not be caused by the environmental context of the archaeological deposits, and could be due to other causes such as site function, site formation process and so on. Re-calculation of mean sizes of the assemblage in both rock shelters is not completed yet.

This means that about 50% of all identifiable elements were used for identification, and that the proportion of identifiable fish remains was about 25 % in these trenches compared with Trench D3, where the proportion was just 14%. Taking into consideration all the results of different stages of analysis, il can be concluded that the fish caught by the people in prehistoric Bukit Tengkorak were mostly inshore coral fishes, especially fishes that inhabit relatively shallow water. The number of pelagic fish such as tunas was very small. As commonly admitted, the main purpose of analysing fish remains is to reconstruct the range of the prehistoric fishing area and estimate the fishing methods and techniques used by the prehistoric people of a certain site. It can be concluded that the main fishing area used by prehistoric people in Bukit Tengkorak was limited to the coral reefs near the site. However, the results of analysis of fish remains alone are not sufficient to reconstruct prehistoric fishing methods and techniques. It is therefore worth applying ethnological data on the Bajau people who have lived near the site in recent times. GENERAL CHARACTER OF MODERN BAJAU FISHING IN SEMPORNA Bajau people11 are a major ethnic group who comprise more than 90% of the total population in Sempoma district today. Traditionally, Bajau people were famous for their maritime-based subsistence and life style as boat dwellers and full time fishermen 12, hence they have often been referred to as "sea gypsies" or " sea nomads" in the literature. However, since the mid-twentieth century, most Bajau people have tended to live in pile houses on the coral terrace near the coast of Sempoma peninsula and its surrounding islands and no-one now lives on boats except a few families drifting around the Sulu Islands to Sempoma sea Their life style and subsistence have also changed fairly rapidly since last century, although more than half the population of Bajau people are still engaged in fishing as full time fishermen. Notl1ing is known directly of Bajau people before the early sixteenth and seventeenth centuries (Sather 1997). However, according to a linguistic reconstruction by Pallesen 11 Bajau people in the Sempoma area conunonly identified themselves as "Sama Dilaut" or "Sama Mandelaut", names that mean literally, "sea" or "maritime Bajau". The cognate terms "Bajau" and "Bajo" appear with regularity in botl1 English and Dutch ethnographic literatures from the early eighteenth century onward (Sopher 1977). The name "Bajau" is not. however, a Sama autonym. The term in the form of "Bajau" has been estimated as Malay or Brunei in origin (Evans 1952; Pallesen 1985; Sather 1997). 12 Until recently, Sama-Bajau language was thought to belong to the Philippine phylum of Austronesian languages (Sather 1978). However, it is now recognised by linguists as comprising a separate Sama-Bajau subgroup within the Western Malayo-Polynesian language family (Sather 1997). Lexical reconstruction suggests that these people were predominantly sea-oriented, but not exclusively so. Also, the reconstructed lexicon points to a long familiarity witl1 farming, iron-forging, pottery-making and weaving, as well as with fishing and seafaring. Although their knowledge of the sea may have been intimate, these early proto-Sama-Bajau speakers were by no means wholly sea people. Ono: Prehistoric fishing at Buk.it Tengkorak 95 (1985), a Sama-Bajau language group can be traced only lo the firsl millennium AD. Around AD 800, speakers of proto Sama-Bajau can be placed with some confidence in the northern islands of the Sulu Archipelago, on Basilan, and along the adjacent Mindanao coastlines bordering the Basilan StrailS (Pallesen 1985). This linguistic reconstruction suggeslS a similarity between proto-Sama-Bajau speakers and prebisLoric people in Bukit Tengkorak. Observations were carried out in some Bajau fishing villages in Bumbum Island, the biggest island in Semporna area, located just in front of Sempora town and Bukil Tengkorak (Fig. 5). The ultimate objective of collecting delailed data about U1e fishing practices of Bajau people is lo reconstruct the prehistoric fishing practice of Bukil Tengkorak and to acquire infonna tion about the geo-ecological features of the fishing area around the sile. However, the observations have been carried out only since 2000, and data are still limited. Therefore, only the basic varieties of Bajau fishing are described here, and some case studies of their fishing activities in recent times are introduced and discussed. Table 9 shows the varieties of traditional Bajau fishing in and around Sempoma. These data were compiled from previous ethnological works conducled by Sather in Sempoma (Sather 1984, 1985, 1995, 1997) and by NagaLSu in Ule Sitankai Islands, about 100 km away from Semporna (Nagatsu 1995, 1997)13 .

As a lot of Bajau people still kept their traditional fishing practices in Ule early 1990s, their data are useful for reference purposes. 96 NEW ZEALAND JOURNAL OF ARCHAEOLOGY fishing lechniques, with a greal variety of methods. On the other hand, there are fewer varieties of line fishing . For example, there was no pelagic trolling by Bajau people and in most of the cases, only simple band line fishing in depths of 10-20 m was practised. The minor importance of pelagic trolling targeting tunas is possibly related to the traditional avoidance or dislike of tunas by the Bajau people. In Nagatsu's (1995) study on cognitional meaning of fish names in Bajau (or Sama language), he found less variely in names for tuna compared with other fish 14• Other lypes of fishing such as spearing, poisoning, trapping, and general foraging are also practised. Spearing is usually done at night, and major fish caught are rays, rabbit fishes, squids and sea turtles . Poisoning is employed in a shallow coral reef environment to catch fish living behind large coral heads, such as long-tailed catfish and groupers. Traditionally, roots of the tuba plant (Derris elliptica) are used as the poison. For trapping, usually about 10-m-long weirs called kelong are erected in the shallow water near the villages. Kelong are made from mangrove trees, and each village usually owns one or two kelong near by. Many kinds of fish are caught using kelong 15 . The methods of traditional Bajau fishing have many varieties, and most of them are practised even now. The major lechniques are various kinds of net fishing such as amokot, agalinggiq (the same fishing style as the so-called 'anakap' and 'binakat' in the 1960s) and amahang. However, magambit, which is the highly co-ordinated fonn of net fishing in connection with large-scale fish drives16 is disappearing, and large scale ne t fishing has also vanished. Bombing was introduced from the Philippines to Semporna in the 1970s and has been practised by some fishermen since then. It was prohibited by the government in the late 1970s because of the danger it poses to the coral reefs. However, some fishennen still prefer to use this illegal fishing method even now (Ono 200lb). Table 10 shows examples of fishing activities by the villagers of Kampong Tongkaloh in Bumbum Island in 200017 (Fig. 5). Net fishing produces much more fish in a much shorter time compared with other fishing styles, and an the fishing takes place on a shallow reef flat, around 0-2 m deep depending on the tide. During the observations, the major fish 14 He also reported that tunas are one of Ute most avoided fish among Bajau people, mainly because of their bloody flesh (Nagatsu 1997). 15 According to Sather, no owners had licenses for kelong at the time of his first research during 1964-1965, although in 1979 there were 67 licensed kelong in Semporna district (Sather 1997) . The number increased from 1980 to the 1990s according to the annual report of the Fisheries Department of Sabal1 (Jabatan perikanan Sabah 1980-1995). 16 According to Sather's study of Semporna Bajau people in the 1960s, magambit fishing was one of the major sources of the best quality dried fish produced by Bajau people in 1964-1 965, though this fishing was observed only imermittently in 1974 and had totally ceased in 1979 (Sather 1997: 127). 17 Kampong (village in Malay) Tongkaloh is located on the southeastern edge of Bumbum Island, just opposite the side of Semporna peninsula where Bukit Tengkorak is situated. There is a huge and beautiful coral reef terrace in front of the village, called Creagh reef, which extends to Menampilik island at its southern edge, about 3 km from Tongkalob (Fig. 5).

Rabbit fishes were mainly caught by netting or spearing. Emperors and wrasses were caught by band line fishing and most of the rays were caught by spearing (Ono 200lb). Rabbit fishes were mainly caught in Zone A, located at the northern side of Kalindingan Island, and damsel fishes were the major fish of the landings in Zone B, on the coral terrace near the village (Fig. 5). According to the villagers, rather big fishes such as jacks and longtoms are usually caught in 10-20 m depth around the coral reef flats. These facts indicate that the fishermen know the habitat of each fish in the shallow reef around their village, and that they can catch the fish in their habitat zones in the coral reef. THE GENERAL CHARACTER OF FISHING IN BUKIT TENGKORAK As shown above, the dominant fish taken by the prehistoric fishennen of Bukit Tengkorak were parrotfish, members of the Scaridae family. These fish are nonnally the major fish diet fo r Pacific people (Davidson et al. 2002; Leach et al. 1996; Masse 1986; Kataoka 1991). They generally live on a shallow coral reef, and are usually caught by netting or spearing at night. The next most abundant fish families were Labridae, Serranidae and Lethrinidae. These groups of fish include many kinds of wrasse, rock cod, grouper, coral trout and emperors. They tend to be bottom feeders and live in a shallow coral reef to a deeper coral sea depending on species. Most of them are usually caught by baited book in deeper water, and sometimes by poisoning and spearing in shallow water. Snappers (Lutjanidae) and trigger fishes (Balistidae) were the next major fish caught in Bukit Tengkorat. Snappers prefer to live around 20--60 min depth and are generally caught by netting or baited book. Trigger fishes are carnivorous and feed on a wide range of bottom-feeding animals, using their powerful jaws to crush prey. These fish tend to live in shallow coral reefs around 5-30 min dep1.h and are commonly caught by netting or baited books. Porcupine fishes (Diodontidae) and Sweetlips (Haemulidae) were also commonly caught in Bukit Tengkorak. Porcupine fishes tend to inhabit shallow coral reefs and are caught by general foraging in shallow water during the daytime. Sweetlips prefer to live on coral reefs around 10-30 m in depth, and are generally caught by netting and baited hook. Only the vertebrae and teeth of cartilaginous fish such as sharks and rays were counted, but they have not yet been identified to lower taxa because of limited comparative material. However, it is worth mentioning that these cartilaginous fish (Elasmobranchii) were also commonly caught in Bukit Tengkorak. Rays, especially, are easily caught by spearing during night fishing and are commonly caught, even in recent times, around Bukit Tengkorak. Sharks are mainly caught by baited hooks. Anotber feature of the fish remains in Bukit Tengkorak is tl1e general lack of pelagic fish such as tunas (Scombridae) and jacks (Carangidae) in t11e assemblages . No cranial bones of tunas were identified in the first stage of tl1e analysis. When other elements such as caudal peduncle and other vertebra portions were analysed, only one vertebra was identified as Scombridae. These results strongly suggest that pelagic fishing was far less important for the people in Bukit Tengkorak, or that t11ey disliked and avoided pelagic fish during Neolithic times. 100 NEW ZEALAND JOURNAL OF ARCHAEOLOGY BUKIT TENGKORAK CATCH COMPARED TO OTHER PACIFIC ISLANDS Excavations in Bukit Tengkorak have suggested a cultural connection with some prehistoric sites in the Pacific islands, especially those related to the Lapita cultural complex in Melanesia. The main basis for this suggestion is the excavated obsidian tools and fragments, some of which have been shown to originate from Talasea in northern New Britain (Bellwood and Koon 1989; Chia 1997). The Talasea obsidian sources were used by Lapita people, and the Bukit Tengkorak discovery of this material increased its distribution at about 1000 BC to 6500 km, from Borneo to Fiji (Bellwood 1989, 1997). Besides the obsidian, other artefacts such as red slipped pottery in both areas suggest a possible relationship between Bukit Tengkorak and other prehistoric sites in western Melanesia and the Pacific islands during the second to first millennia BC. However, the most specific similarity is possibly the subsistence patterns, which might be characterised as highly maritime-oriented. At Bukit Tengkorak, the proportion of fish bones in the total amount of excavated faunal remains was very high. Moreover, marine turtles were most numerous in the animal remains, according to the results of the 1994-1995 research (Chia 1997). These facts characterise the nature of subsistence in prehistoric Bukit Tengkorak, which is located on the edge of the eastern coast of Borneo Island with a huge land and forest area behind the coast line. When we compare the result of the analysis of fish remains from Bukit Tengkorak with those in the Pacific islands, there are some common features and some differences. When the MNI of fish from eight archaeological sites18 in the Pacific region were combined (Leach et al. 1996: Table 16), the proportion of excavated coral fish tended to surpass that of pelagic fish (Table 11). Interestingly, all top seven fish in these eight archaeological sites live in and around coral reefs, although pelagic fish such as tunas and jacks are also among the major fish caught in some Pacific islands. Table 12 presents the relative importance of the different methods of fishing of the Bukit Tengkorak people, based on the ethnological data on Bajau fishing and the general habitat of each fish . As Leach er al. (1988) have pointed out, interpreting bow people caught fish from archaeological remains is fraught with difficulties. and their conunents should not be read too literally. The approach taken here is just to make an assessment about the most likely catch method employed based on the information mentioned above. Table 12 suggests that the prehistoric Bukit Tengkorak people caught most of their fish (51.5%) by baited hook and line fishing. This percentage of line fishing is rather high, even compared with other assemblages from the Pacific. Serranidae, Lethrinidae, Labridae and Lutjanidae are the main fish usually caught by line and baited hook. However, these fish are also sometimes caught by netting, according to ethnological observations. Netting comes next in importance at Bukit Tengkorak (32.5%). A high proportion of netting is a feature of many Pacific islands and also of traditional Bajau fishing. Scaridae, Balistidae and Siganidae form the bulk of the fish mainly caught by this technique. 18 These sites were Huabine, Mochong in Rota, Pohnpei, Nan Madol, Kapingamarangi, Nukuoro, Palau and Rota airport sites (Leach et al. 1996). 101 Ono: Prehistoric fishing at Bukit Tengkorak TABLE 11 COMBINED MNI OF FISH FROM EIGHT PACIFIC ARCHAEOLOGICAL SITES Source: Leach et al. 1996: 338, Table 16 No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 Total Family Scaridae Serranidae Lethrinidae Nemipteridae Balistidae Labridae/Coridae Lutjanidae Carangidae Elasmobrancbii Scombridae Anguillifonnes Diodontidae Holocentridae Acanthuridae Mullidae Coryphaenidae S ph yraenidae Ostraciidae Belonidae Tetraodontidae Istiophoridae/X yphiidae Acanthocybiidae [Scombridae] Siganidae Kyphosidae Scorpaenidae Aluteridae [Monocanthidae] Plectorhyncbidae Bothidae Gerreidae Mugilidae Caesionidae Platacidae [Ephippidae] Exocoetidae Megalopidae Channidae Hemirarnpbidae Apbareidae [Lutjanidae] Pempheridae MNI 1686 603 482 459 457 392 337 314 273 259 227 223 204 89 70 67 44 42 38 29 27 18 16 14 14 13 7 6 6 5 4 3 2 2 I l l l 6436 102 NEW ZEALAND JOURNAL OF ARCHAEOLOGY TABLE 12 MINIMUM NUMBERS BY CATCHING METHODS AT BUKIT TENGKORAK % Likely Catch Method MNI Netting Scaridae Balistidae Siganidae Mugilidae Mullidae Pomacanthidae Baited hook Labridae/Coridae Lethrinidae Lutjanidae Haemulidae Nemipteridae Sparidae Platycephalidae Pelagic lures Carangidae Sphyraenidae Spearing Elasmobranchii Trapping/poisoning Muraenidae Ariidae General foraging Diodontidae Tetraodontidae 550 32.5 871 51.5 4 0.2 154 8.1 11 1.5 54 3.1 Perhaps the most significant feature of prehistoric Bukit Tengkorak fishing is U1e very minor role of pelagic lure fishing . TI1e proportion in Table 12 (0.2%) is extremely low compared with other Pacific archaeological assemblages of fish remains. Spearing accounts for 8. 1% and general foraging activities for 3. 1%. The relatively high percentage of spearing is due to the idea that Elasmobranchii are caught by spearing. However, according to the ethnological information, rays are commonly caught by spearing, but most sharks are caught by baited book. Spearing is also important for catching sea turtles and sea mammals such as dolphin in Bajau fishing. General foraging is an important method for collecting shells, sea urchins and sea cucumbers, and Ulis method might have been commonly employed in prehistoric Bukit Tengkorak, since a huge quantity of shells was also recovered from the site (Chia 1997). Comparison of the results of the analysis of Bukit Tengkorak fish remains with those in the Pacific islands revealed the same tendency in major and minor fish caught. However, the proportions of Carangidae (jacks and trevallies) and Scombridae (tunas) are extremely small in Bukit Tengkorak, while the proportion of Siganidae (rabbit fishes) is rather high compared with other sites in the Pacific. According to the ethnological observations in Ono: Prehistoric fishing at Bukit Tengkorak 103 Sempoma area, these fishes are commonly caught and are also preferred by local Bajau people. These facts tentatively suggest that the prehistoric people in Bu.kit Tengkorak really preferred to conduct their fishing only around tJ1e inner reefs near tlle site. This line of evidence leads to the idea that tlle prehistoric Bu.kit Tengkorak people benefited from the abundance of marine resources inside coral reefs and also from the land resources in Sempoma peninsula. The people might not have needed to go out to the pelagic seas to catch tlle bigger pelagic fish, or there might have been other reasons such as avoidance of pelagic fish or dislike of them, just like the traditional Bajau community in Sempoma region. CONCLUSIONS Twenty-eight taxa were identified during the analysis of fish remains from Bukit Tengkorak. Altllough tlle deposits cover a long period. no chronological change in fish remains is apparent in any individual excavation. There are, however, some differences between the soutllem and the nortllem rock shelters, such as temporal variety and tJ1e size of fish bones. The number of fish types taken is more limited tl1an expected for such a large assemblage of fish bones. The major fish caught in Bukit Tengkorak are coral fish such as Scaridae, Labridae, Serranidae, Lethrinidae, Lutjanidae, Balistidae, Siganidae and Diodontidae. The number of identified pelagic fish such as Carangidae, Scombridae, and Sphyraenidae is extremely low, even when vertebrae were used for identification. In terms of temporal change, t1le numbers of each taxon tend to be larger in Layers 2 to 5, especially Layers 2 and 3, while the numbers in Layers l and 6 are generally small. This suggests iliat all ilie major fish could be caught from early to late Neolitllic by the people in Bukit Tengkorak, but tJie intensity of fishing activity was greater during t1le middle Neolithic time, dated around l 000-800 BC. Ethnological observations of local Bajau fishing near tlle site revealed that most of tlie fishing activities took place inside the coral reef. The et1lnological infomJation regarding traditional and modem Bajau fishing patterns showed the same tendency: ilie major importance of netting and line fishing. These results indicate ilie reason for the much lesser importance of pelagic lure fishing in tlle subsistence of ilie prehistoric people in Bukit Tengkorak compared with oilier archaeological sites in ilie Pacific.
