Toward the Historical Archaeology of Levuka, a South Pacific Port of Call

In the latter half of the nineteenth century, the Fijian port of Levuka alternately passed through incarnations as a beachcomber community, boisterous port of call, commercial entrepôt, and colonial capital. Initial investigations in this town in 2000 provide a data set through which archaeology's potential for a meaningful dialogue on Levuka's past can be explored. These data reflect upon an increasingly segregated European community structure, through which social transformations in alcohol use, landscape alterations, and material culture consumption patterns are examined.     

Stone anchors from the Mediterranean coasts of Anatolia, Turkey: underwater surveys and archaeometrical investigations

This study is mainly based on the expeditions and underwater study of stone anchors from the Cilician coast, Bodrum Museum of Underwater Archaeology and the Kaš Uluburun wreck. The stone anchors found on the Cilician coast are very similar to eastern Mediterranean stone anchors with respect to shape and characteristics. The stone anchors from BMUA and KUW were examined by thin section and XRD analysis. They are made of volcanic, sedimentary and metamorphic rocks. The study indicates that the anchors are similar to others found in the Mediterranean.     

Hohokam Craft Economies and the Materialization of Power

The Prestige Goods Economy Model invoked by archaeologists to explain the development of power in middle-range societies generally fails to discriminate the varied roles of social valuables. This study illustrates a multi-faceted approach for identifying the symbolic utility of craft economies among the Hohokam in North America. Contextual analyses of marine shell artifacts disclose their functions as material symbols of group membership and identity, ritual performance paraphernalia, instruments of power, and insignia of office. These valuables were imbued with ideological meanings that legitimized the emergence of corporate modes of power from individualized networks. Applications of the Prestige Goods Economy Model in other world regions would also be enriched by more detailed examination of the meanings of social valuables.     

Cattle Before Crops: The Beginnings of Food Production in Africa

In many areas of the world, current theories for agricultural origins emphasize yield as a major concern during intensification. In Africa, however, the need for scheduled consumption shaped the development of food production. African cattle were domesticated during the tenth millennium BP by delayed-return Saharan hunter-gatherers in unstable, marginal environments where predictable access to resources was a more significant problem than absolute abundance. Pastoralism spread patchily across the continent according to regional variations in the relative predictability of herding versus hunting and gathering. Domestication of African plants was late (after 4000 BP) because of the high mobility of herders, and risk associated with cultivation in arid environments. Renewed attention to predictability may contribute to understanding the circumstances that led to domestication in other regions of the world.

Experimentally produced glass compared with that occurring at The Torr, NW Scotland, UK: vitrification through biotite melting

It is proposed that the vitrification in some Iron Age forts in NW Scotland can be explained through decomposition of micas (largely biotite) giving melts that react with or dissolve quartz and crystallise orthopyroxene and feldspars, so equating with the reaction biotite + quartz = sanidine + orthopyroxene + liquid. A sample of Moine semi-pelite has been experimentally melted at c. 850 °C demonstrating this breakdown reaction. A preserved thermal gradient across the sample reveals the progressive degradation of biotite towards the melting (upper) surface. Degradation is evident from the initial emphasis of mica cleavages in grains at the bottom of the sample, and then appearance and progressive increase in size of bubbles associated with biotite and melt towards the top of the sample. A chocolate-brown melt was produced as a coating on the upper surface and along micaceous layers. A near equivalent sample was located from the fort at The Torr that, whilst being more thoroughly affected by heat, with no unaffected biotite, preserved similar textures. Compositions of original Moine minerals are used to constrain the melts produced and melt evolution is tracked through quenched crystals. These include ternary feldspars as well as sanidine, spinels and orthopyroxene. Spot geochemical evidence demonstrates the heterogeneity of the melts, plus varying contributions of Ca and Na that could be attributed to the onset of reactions involving feldspars and other minerals from the original assemblage. It is thus concluded that a similar temperature to that of c. 850 °C derived in the experiment was reached in the vitrification process at The Torr in order to produce the glass observed.

Going underground: experimental carbonization of fruiting structures under hearths

We show that carbonized fruits and seeds recovered from Middle Stone Age deposits in rock shelters are likely to have been carbonized as part of post-depositional processes. We buried indigenous South African fruits, nuts and seeds at pre-determined depths and distances from the centers of experimental fires. The cold ashes of the hearths and the sand surrounding them were subsequently excavated, using standard archaeological techniques and dry-screening. The fruiting structures from the oxidizing part of the fire were burnt to ashes, whereas those buried in sand under anoxic conditions survived in varying forms. Those buried 5 cm below the center of the fire were carbonized; those buried 10 cm below the center of the fire were dehydrated; and those 5 cm and 10 cm below the surface at the outer edge of the fire were unaffected. Size, moisture or oil content of the original fruit or seed did not appear to influence whether or not carbonization took place. Temperatures recorded 5 cm below the experimental fires suggest that the carbonization occurred at or before a maximum temperature of 328 °C, and also at lower maximum temperatures (152 °C) that were maintained for long periods. Even when the quantities of a particular wood are controlled, open fires may produce variable underground temperatures and the temperatures below ancient hearths would have been equally variable. We suggest that Cyperaceae (sedge) nutlets, the most numerous fruiting structures in the Sibudu Middle Stone Age archaeobotanical assemblage, occur in the shelter as a result of human activity, subsequent burial, and accidental carbonization when hearths were built directly above the buried nutlets.     

Palynology and archaeological inference: bridging the gap between pollen washes and past behavior

Credible interpretation of pollen recovered from archaeological sites hinges upon understanding how pollen becomes deposited by both the environment and human behavior. The environmental role has been studied to some extent, but how the activities of people have formed the pollen assemblages at archaeological sites is usually just assumed rather than considered explicitly. Moreover, the complexity involved in the interaction between human behavior and pollen ecology is seldom considered. An archaeological case study of grinding tool pollen washes highlights the ambiguities of standard practice because the results confound common assumptions about pollen washes. A series of experimental seed and grinding tool washes designed to test the relationships between the processing of seeds and the deposition of pollen help explain why, for most situations, artifact pollen washes do not provide direct or even faithful records of plant processing. These results highlight the need for further experimental research with pollen so that we are warranted in making behavioral inferences from palynology. This conclusion is easily extended to other microbotanical data classes that archaeologists regularly employ.     

Comparing the survival of osteocalcin and mtDNA in archaeological bone from four European sites

The small mineral-binding bone protein, osteocalcin, has been applied in a number of studies on ancient bone due to predictions of its long-term stability. However, the intact protein has not been shown to survive in ancient bone devoid of DNA, which is a much more phylogenetically informative biomolecule. In this investigation, the survival of osteocalcin is directly compared to the amplification of mtDNA in a set of 34 archaeological samples from four sites throughout Europe. We also present unpublished osteocalcin sequences of seven mammalian species in addition to the 19 published sequences to highlight phylogenetic limitations of this protein. The results indicate that the intact osteocalcin molecule survives less in archaeological samples than mtDNA and is more subject to the temperature of the archaeological site. Amino acid analyses show the persistence of the dominant protein collagen in samples that failed both osteocalcin and mtDNA analyses. The implications these findings present for biomolecular species identification in archaeological and palaeontological material are that, although proteins do survive beyond ancient DNA, osteocalcin does not appear to be the most ideal target.
