10,000 years of human predation and size changes in the owl limpet (Lottia gigantea) on San Miguel Island,California

To investigate potential human impacts on California Channel Island shellfish stocks over the past 10,000 years, we measured 1718 owl limpet shells from 19 archaeological components on San Miguel Island. Inhabiting the middle intertidal zone of Pacific Coast rocky shores, owl limpets are slow-growing mollusks that can live for 30 years and reach lengths of over 100 mm. Recent ecological studies indicate that owl limpets are highly susceptible to heavy human predation, which results in reduced mean shell sizes among Lottia populations along the coasts of Alta and Baja California. On San Miguel Island, we identified a significant trans-Holocene reduction in mean owl limpet size, beginning more than 6500 years ago and accelerating at least 4400 years ago. Fluctuations in limpet size show no clear correlation with changes in sea surface temperature and marine productivity, suggesting that increased predation by growing human populations was primarily responsible for the reduction in Lottia size over time. Our results provide further evidence that prehistoric peoples significantly influenced nearshore fisheries long before the development of the commercial and industrialized fisheries of historic times.     

社区考古学:文化遗产管理还是考古学研究

社区考古学反映了一种全新的文化遗产管理和考古学研究的思路,其实践仍然具有草创性、不平衡性和多元性。社区考古学是作为让本土社会获得考古学权力的工作方式,以权力让渡为核心,主要涉及发掘权、阐释权、教育权和商业开发权。社区考古学理念确立了社区在文化遗产管理的主体观念,廓清了中国的生态博物馆运动对生态观念和文化保护与经济发展的关系的误解。在考古学研究上,社区考古学是情境考古学的表现形式,将通过采取不同的视角揭示传统考古学研究所无法触及的问题。

Excavation and Study of Skeletal Remains from a World War I Mass Grave

This study presents the excavation and multidisciplinary analysis of seven skeletons recovered in a World War I Mass Grave on the mountains of the Veneto Region, Italy. While it is not a rare phenomenon to these mountainous areas involved in the First Conflict, it is exceptional, on these mountains, to find a mass grave with soldiers in primary burials. Stratigraphic excavation was the mean used for recovery, along with 3D laser scanning documentation. Every skeleton but one was found complete and in anatomical connection. Four soldiers lay in the prone position; two subjects were lying on their side. Identification of the nationality was performed for two of the subjects, who both of whom had personal effects such as a badge for military vaccinations and religious medals. What remained of their uniforms gave clues about their Italian nationality. The entomological analysis conducted on fly puparia discovered close to the bones revealed that the bodies had not been buried immediately. The skeletons were biologically profiled by sex, age, height and ancestry. An accurate study of pathology and stress markers was carried on, as well as on skeletal trauma in order to establish the type of trauma and ammunition involved. The remains belonged altogether to seven Italian male soldiers ages between 18 and 35. Various kinds of stress markers revealed occupational (enthesopathies) and metabolic stress: several signs of cribra cranii and of cribra orbitalia were registered. The study of the injuries revealed a surprising variety of types of lesions, mostly lethal: a few subjects were struck by a shrapnel grenade; one soldier was killed by a grenade explosion. Two of the soldiers were probably executed, instead: this conclusion reached on the basis of gunshot holes (9 mm) in their skulls, and by the position of the injuries.

Charcoal analysis and dendrology: data from archaeological sites in north-western France

During the last 15 years, charcoal analysis of archaeological sites in north-western France has been carried out in conjunction with systematic and detailed dendrological examination. By considering these extrinsic criteria in association with the analytical results, palaeo-ethnographic and palaeo-environmental information can be obtained. The charcoals are classically identified under the microscope on the basis of their cellular structure. This examination is associated with an observation of the ligneous structure on transverse sections using a binocular lens. When charcoal fragments are large enough, the growth ring widths are measured. Tree ring curvature is also noted. Finally, alteration by fusion or radial cracks, the presence of fungal hyphae, and insect degradation are also recorded. Results are thus obtained on the nature of fuel used in domestic fireplaces and kilns. The selection of timbers and their catchment areas are also revealed. The average width of the growth rings in oak charcoal from domestic hearths coming from about forty sites in north-western France shows a significant increase from 6000 to 2000 BP. There is a similar increase in the number of heliophilic taxa used from the Neolithic to the Iron Age. This implies that the environment became more and more open because of use by society. The interpretation of the dendrology results applied to charcoal analyses is obtained through a convergence of criteria. Thus, charcoal analysis can provide more than just an identification of the species used, and can yield fundamental information on the interaction of society with the environment.     

The emergence of status inequality in intermediate scale societies: A demographic and socio-economic history of the Keatley Creek site,British Columbia

Explaining the emergence of status inequality in human societies is an important priority for many anthropological archaeologists, particularly those whose research includes intermediate scale societies (complex hunter–gatherers and early agriculturalists). Yet, fine grained records of emergent inequality are still exceedingly rare. This paper outlines a fine-grained record of cultural change from the Keatley Creek site, a complex hunter–gatherer village in British Columbia, in which it is possible to recognize the emergence of inequality and its demographic and economic correlates. Results of the study suggest that status inequality emerged abruptly after an extended period of socio-economic stability in the village under conditions of adversely altered resource conditions, demographic packing, and subsistence resource diversification and extensification.     

Raman microprobe analysis of stucco samples from the buildings of Maya Classic Copan

Micro-Raman spectroscopy has been applied to painted stucco samples from three buildings at the Maya site of Copan, Honduras. The buildings, Clavel (AD 450–550), Ani (AD550–650) and Structure 10L-22 (AD730,) date from three phases of the Classic Period (AD400–820) acropolis construction. The red pigment has been identified as haematite and the stucco as a mixture of calcite particles dispersed throughout a calcite based lime wash stucco. The physical structure of the stucco changed through time, indicating a refining of production techniques over this period. By combining Micro-Raman spectroscopy with other micro-ATR infrared spectroscopy and environmental scanning electron microscopy a detailed investigation of the materials and production techniques used to decorate these buildings has been made. Differences in the mineralogy of the red pigment used on each building indicate a different geological pigment source for each period.

Spinning Yarns: The Archaeological Evidence for Hand Spinning and its Social Implications,c ad 1200–1500

THIS PAPER EXAMINES the archaeological evidence for hand spinning in medieval Britain from c 1200 to c 1500. Ceramic, stone and baked clay spindle whorls have dominated the excavated finds, but a new corpus of lead-alloy spindle whorls, recorded through the Portable Antiquities Scheme and Scottish Treasure Trove, is presented here. Analysis of the metal whorls’ distribution, manufacture, dating and decoration is provided, illuminating the wide social and economic contexts in which they were used. From memento mori of pious spinners to sexually potent objects representative of lubricious gossips, the ubiquitous spindle whorl was a universal tool that had a powerful agency. The artefacts are small finds embodying daily life but also tie into the wider national economy of the High and Late Middle Ages.     

The medieval to early modern transition in a digital age: new developments relevant to the study of domestic buildings

SUMMARY: Transitions in the archaeological and historical record are difficult to discuss and frequently avoided. The authors briefly outline here how this topic has been studied, particularly in Post-Medieval Archaeology, reviewing differences of approach between European-based archaeologists, who stress continuities with medieval times, and archaeologists in the USA and elsewhere, who commence their studies with the arrival of Europeans. This outline is then used to explore how this earliest formative era of the post-medieval period can be studied via modern digital techniques, using a case study drawing on the study of buildings archaeology to further understanding of the transition. This 50th-anniversary contribution therefore intentionally bridges the old and the new.
