For each bone, we took between 2 and 5 measurements and plotted the obtained values against the fork length. For the osteometric model, we used the neurocranium, premaxilla, dentary, anguloarticular, quadrate, hyomandibula, maxilla, opercle, anterior and posterior ceratohyals, scapula and vertebrae. lineatus, the relationship is W = 2E-05 FL2.9578, with r2 higher than 0.98 for both species. affinis, the length-weight relationship is W = 1E-05 F元.0682, and for E. lineatus (FL: 294 mm to 614 mm, W: 481 g to 4200 g) from Ecuador. affinis (FL: 274 mm to 828 mm, W: 305 g to 8674 g) from the Sultanate of Oman and 26 specimens of E. Therefore, we built an osteometric model for these two species, using 31 specimens of E. In archaeology, these studies make it possible to highlight fishing strategies. Size reconstruction from isolated bones is interesting for both biologists and archaeologists.
They have long been exploited and are common finds on coastal archaeological sites. lineatus) from the Indo-Pacific and the Eastern Pacific are today classed as commercially important. Two neritic species of scombrids (Euthynnus affinis and E. However, variability between assemblages screened with 6.4 mm and 3.2 mm mesh and those screened with only 6.4 mm mesh are discussed in the results. As very few scombrid bones were reported in the 3.2 mm screens, these sampling proto- cols did not influence the observed trends. All excavated sediments were wet- screened through 6.4 mm mesh, and only TP 6 and TP 17 (MLEb-1) and TP 13 (MLEb- 5) were sieved using 3.2 mm mesh. The dates, re- ported here, are all on coconut husk or shell and calibrated to two standard devia- tions (with median reported) using IntCal09 curve and the OxCal program ( Reimer et al.
Only four AMS radiocarbon dates from the sites discussed here were in- cluded, but the comprehensive Ebon Atoll chronology developed from 59 radiocar- bon and U-series dates (Weisler et al., in prep) supports a model of continuous oc- cupation over two millennia. With 11 documented archae- ological sites on Ebon Islet, we focus on MLEb-1 and MLEb-5 ( Figure 2), as these sites provide well-preserved early, middle, and late period prehistoric faunal assem- blages.
Ebon Islet as the largest islet, with the most developed Ghyben-Herzberg fresh- water lens, hosts the most extensive vil- lage and horticultural systems and the old- est habitation sites (Weisler 2001a Weisler et al. field seasons (1995)(1996)(2011)(2012)) of survey and excavation were di- rected by Weisler (2002) on Ebon Atoll.
