Ground Penetrating Radar in the Northern Great Lakes: A Trial Survey of a Contact Period Occupation in Marquette County,Michigan

ABSTRACT

Timing, inclement weather, and limited budgets can obstruct archaeological survey efforts. Here, we ameliorate some of these with use of ground penetrating radar (GPR) at the Goose Lake Outlet #3 (GLO#3) site (20MQ140). GPR surveys to guide survey and excavation efforts in these well-drained sandy soils are limited. GPR imagery exhibited false positives; however, shovel probes, subsequent site excavation, and artifact analysis led to numerous discoveries at this protohistoric site—including glass trade beads dating to the 1630s. These discoveries solidify evidence for some of the earliest European-made trade items in the region and provide further confirmation for placement of an Indian trail and ancient travel corridor between Lake Superior and Lake Michigan. Two ¹⁴C samples obtained from moose-bone in features with trade goods fall within the expected occupation range of 1633–1668 and 1615–1647. Several anomolies, possible hearth clusters were seen on the GPR imagery; however, many features remained invisible.     

Diet and Oral Health of Populations that Inhabited Central Argentina (Córdoba Province) during Late Holocene

The aim of this work is to study, from a bioarchaeological perspective, the diet and oral health of the populations that inhabited Central Argentina in two periods which would reflect changes in subsistence strategies: earlier late Holocene (ca. 2500–1500 years BP) and later late Holocene (ca.1500–400 years BP). The sample is composed by 83 adult individuals from 47 archaeological sites. We considered five non‐specific indicators of stress, infectious and degenerative diseases: hypoplasia of dental enamel, dental caries, abscesses, antemortem teeth loss, and calculus. We also considered hypercementosis, dens in dens, and agenesis. We test intraobserver error by means of intraclass correlation coefficient and analysis of variance of repeated measures. We calculated prevalence by sex, age, geographic subregion, and chronological period. We applied Chi‐square (X²) to test statistical significance of observed differences. Considering the sample as a whole, low prevalence of dental caries (10.27%), abscesses (16.52%), and hypoplasia (10.84%) are coincident with values observed for populations with mixed or hunter‐gathering subsistence strategy. In later late Holocene, high incidence of caries should be considered as indicator of consumption of C4 vegetables or other carbohydrate‐rich vegetables, such as legumes of Prosopis sp. Also, moderate values of dental enamel hypoplasia should be related with metabolic‐systemic stress episodes. Summarizing, these results are coincident with isotopic, archaeological, and ethnohistorical evidences which suggest climatic, social, and demographic pressures that might have affected the lifestyle of these populations before the Spanish conquest.

A NEW METHOD FOR EXTRACTION,ISOLATION AND TRANSESTERIFICATION OF FREE FATTY ACIDS FROM ARCHAEOLOGICAL POTTERY

This paper presents evidence for increased recovery of organic residues from archaeological pottery through use of a microwave‐assisted liquid chromatography protocol. C_16:0 and C_18:0 saturated fatty acids were obtained from archaeological potsherds recovered from nine Neolithic settlements in the Middle East dating between 4700 and 7300 cal bc , including materials that had not produced evidence for the survival of any lipid species through use of ‘conventional’ solvent extraction techniques. Compound‐specific isotopic analyses of C_16:0 and C_18:0 fatty acids in potsherd extracts subsequently revealed δ¹³C/δ¹²C compositions consistent with modern subcutaneous fats of wild boar and goats pastured on lands adjacent to the Jordan Valley, and residues from a modern pottery vessel used in the manufacturing of butter, cheese and yogurt in central Turkey. These results are presented as an illustration of capabilities of the microwave‐assisted recovery protocol. The reclamation of saturated and unsaturated fatty acids from archaeological pottery fragments recovered from a number of the earliest ceramic horizons in the Middle East is herewith reported, and the extraction methods and instrumental analytical techniques are described.     

The “Blind” State: Government Quest for Formalization and Conflict with Small‐Scale Miners in the Peruvian Amazon

The Peruvian government is attempting to implement a formalization plan to deal with the chaotic expansion of small‐scale mining activities in the Amazon. However, this plan has been contested, delayed and halted by local miners. Why exactly has it been so hard for the government to enforce a formalization plan in Madre de Dios? This article aims to answer this question by analysing both government efforts to establish control over the region and the challenges it faces in enforcing its formalization plan. It is argued that current resistance to and conflict over the formalization process in Madre de Dios reveals a state governance problem due to the region having been historically governed as a zone for exploitation rather than for social and economic development. Similarly, the analysis highlights the absence of major corporations through which the state can establish a basis for governance, as in other parts of the country.     

A NEW DATE FOR THE NEANDERTHALS FROM EL SIDRÓN CAVE (ASTURIAS,NORTHERN SPAIN)*

Torres et al. (2010 ) published a series of radiocarbon, AAR, ESR and OSL dates from the site of El Sidrón, northern Spain, which is notable for the discovery of the partial remains of 12 Neanderthals. Whilst the non‐radiocarbon methods suggested an age beyond 32 600–46 300 years, direct radiocarbon dates on the human fossils were inconsistent, ranging between 10 000 and 50 000 bp . This study uses the ultrafiltration pre‐treatment protocol to obtain a date of 48 400 ± 3200 bp (OxA‐21 776) on a bone fragment and confirm the antiquity of the Neanderthal assemblage. Moreover, it demonstrates the comparability of the ultrafiltration and ninhydrin bone radiocarbon pre‐treatment protocols, and highlights the need for appropriate screening methods where valuable collections with poor biomolecular preservation are sampled for collagen extraction.     

ORTHOIMAGE‐BASED DOCUMENTATION OF ARCHAEOLOGICAL STRUCTURES: THE CASE OF A MEDIAEVAL WALL IN PONTEVEDRA,SPAIN

During the completion of the expansion works at the Museum of Pontevedra (Spain), a stretch of about 60 m of the medieval walled enclosure surrounding the historic city centre was discovered. Due to its value as a heritage element, the discovery of this archaeological structure required the implementation of preservation activities and exhaustive documentation so that future generations will be able to know and enjoy this piece of history. This paper presents digital models that reproduce the original structure of the wall using close‐range digital photogrammetry, as well as orthophotos, which thoroughly document the dimensional and textural characteristics of the archaeological site. In addition to analysing the accuracy and validity of photogrammetry in the conservation of archaeological heritage, a methodology of data capture, processing and photogrammetry representation is evaluated.     

南京祖堂山南唐3号墓考古发掘的主要收获及认识

祖堂山南唐3号墓位于顺陵西北约100米的南唐陵园西墙之内,其砖室平面呈"中"字形,由甬道、墓室、耳室等部分构成。尽管墓葬早年多次遭盗扰,但仍出土银、玉石等质地遗物40余件。根据墓葬规模、形制、出土遗物的特点以及墓葬在陵园内的位置、遗骸鉴定结果等,墓葬时代应为南唐,墓主极有可能是南唐后主李煜昭惠国后周氏,陵号懿陵。该墓是20世纪50年代初南唐二陵发掘后祖堂山南唐陵区的最重要考古发现。     

Potemkin Revolution: Utopian Jungle Cities of 21st Century Socialism

This paper explores the entanglement of ideology and materiality in the production of the spaces of 21^st century socialism. “Millennium Cities” are currently being constructed for indigenous communities throughout the Ecuadorian Amazon, with revenues derived from petroleum extracted within their territories. As iconic spatial symbols of the “Citizens’ Revolution”, the Millennium Cities would appear to embody “the original accumulation of 21^st century socialism”—a utopian state ideology promising the collective appropriation of natural resources without the dispossession of the peasantry. Drawing on extensive field research, we argue that they are better understood as a simulation of urban modernity that is symptomatic of the predominance of ground rent in South American capitalism, and which conceals the violent repression of an autonomous indigenous project of petroleum‐based modernization. The original accumulation of 21^st century socialism can therefore be interpreted as a “fantasy of origins”, which functions to reproduce the primitive accumulation of capital.     

Ulama in Islamic Law‐Making and Adjudication in Contemporary Egypt

The article examines the legislative and judicial tasks of Islamic jurists and how they carried it out in constitutional or general legal structure. While the Pakistani experiment was inspired by the Iranian model of jurists' involvement in legislatures, Egypt took a different path by not recognizing any official role for Islamic jurists with ambiguous recognition of Islamic jurisprudence. The legislative role could take the form of incorporating Islamic jurists into the legislature, establishing a committee partially made up of Islamic jurists, or handing over some legislative task to an Islamic jurisprudential institution. Despite the fact that Islamization was intended to respond to the people's requests, it employed autocratic and authoritarian mechanisms. The project attempted to replace the typical class of socially recognized jurists with appointed committees entrusted with Islamic codification. The experiment was challenged for its operation and its Islamicity but never introduced Shari'a courts or Islamic clerical legislation.
