Boiled versus unboiled: a study on Neolithic and contemporary human bones

Bones treated at low temperature do not present major modifications although, macroscopically, boiled bones may be distinguished from unboiled ones as they are smoother, lighter and more transparent. Such observations should correspond to textural modifications at a nanometric level and should depend on boiling time. In this study, contemporary human bones, boiled during various time intervals, were characterized using scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and nitrogen adsorption (BET). The results were used to estimate the boiling time in four archaeological samples (Neolithic bones from Malalmuerzo cave, Spain). It is concluded, comparing Neolithic bones to contemporary ones and from the textural characterization at a nanometrical level, that two of the archaeological bones were boiled and that they were boiled for less than 6 hours.     

Raised fields in the Bolivian Amazonia: a prehistoric green revolution or a flood risk mitigation strategy?

The Llanos de Moxos (LM), Beni, Bolivia, with its impressive number of pre-Columbian earthworks, is an ideal region for studying past human–environment interactions in the Amazonia. Agricultural raised fields are among the most striking of those earthworks. They can offer us valuable information about the region’s agricultural carrying capacity and the nature and extent of human occupation in pre-Columbian times and, therefore, help adopt better informed conservation and development strategies for Amazonia in the future. However, before tackling these issues we need to further our understanding of why pre-Columbian raised fields were built and how they were managed in the past. Published data on raised fields in the LM is contrasted with new data gathered from field and remote sensing images. Raised fields have been analysed in relation to the hydrology, soil, topography and paleoclimate of the areas where they are found. In light of this new data we believe that there are grounds to question the current model that suggests raised field agriculture provided high yields without the need of fallow periods, representing a kind of pre-Columbian green revolution. Our alternative proposal suggests that raised field agriculture allowed pre-Columbian peoples to mitigate the risk of more intense and frequent flooding than is experienced today in the LM. We show that raised fields were built only in those areas where there were no alternatives, which do not coincide with those areas where pre-Columbian societies seem to have flourished and reached high levels of social complexity.     

Aviation Archaeology Offshore: The Recovery of a Rare Ju88 Aircraft Wreck during Work for the New London Gateway Port

Abstract

During dredging works for the new London Gateway Port in 2011, fragments of a German Ju 88 bomber were recovered from the Thames Estuary. Subsequent archaeological investigation by Wessex Archaeology, using geophysical survey and divers, resulted in the location of the wreck site and its subsequent recovery under licence in 2012. Post-recovery analysis has enabled it to be identified as a very rare prototype Ju 88T. The aircraft, flown by men of the secretive Luftwaffe special operations unit VOdL, was lost during a reconnaissance mission to record bomb damage at Chelmsford in 1943. The Norwegian fighter ace who shot it down, Marius Eriksen, subsequently achieved fame as a Norwegian skiing champion and actor. The recovery was unusual in that it was carried out as a staged archaeological investigation and in the context of offshore development, where ‘avoidance’ is the usual strategy.

The fusion of law and ethics in cultural heritage management: The 21st century confronts archaeology

Abstract

Archaeologists around the world face complex ethical dilemmas that defy easy solutions. Ethics and law entwine, yet jurisprudence endures as the global praxis for guidance and result. Global legal norms articulate ‘legal rights’ and obligations while codes of professional conduct articulate ‘ethical rights’ and obligations. This article underscores how a rights discourse has shaped the 20th century discipline and practice of archaeology across the globe, including in the design and execution of projects like those discussed in the Journal of Field Archaeology. It illustrates how both law and ethics have been, and still are, viewed as two distinct solution-driven approaches that, even when out of sync, are the predominant frameworks that affect archaeologists in the field and more generally. While both law and ethics are influenced by social mores, public policy, and political objectives, each too often in cultural heritage debates has been considered a separate remedy. For archaeology, there remains the tendency to turn to law for a definite response when ethical solutions prove elusive.

As contemporary society becomes increasingly interconnected and the geo-political reality of the 21st century poses new threats to protecting archaeological sites and the integrity of the archaeological record during armed conflict and insurgency, law has fallen short or has lacked necessary enforcement mechanisms to address on-the-ground realities. A changing global order shaped by human rights, Indigenous heritage, legal pluralism, neo-colonialism, development, diplomacy, and emerging non-State actors directs the 21st century policies that shape laws and ethics. Archaeologists in the field today work within a nexus of domestic and international laws and regulations and must navigate increasingly complex ethical situations. Thus, a critical challenge is to realign approaches to current dilemmas facing archaeology in a way that unifies the ‘legal’ and the ‘ethical’ with a focus on human rights and principles of equity and justice. With examples from around the world, this article considers how law and ethics affect professional practice and demonstrates how engagement with law and awareness of ethics are pivotal to archaeologists in the field.     

Apollo and the Virgin: The Changing Meanings of a Sacred Site on Anafi

The ruins of an ancient Greek temple on a Cycladic island form part of an Orthodox Christian shrine. To local people and returning migrants, the site is that of their patron saint; its pre‐Christian past is irrelevant except in so far as it establishes their specific link with the ancient world, and thus with national claims of unbroken continuity between modern and ancient Greece. To early travellers and antiquarians, and to today’s archaeologists, it has been primarily the ancient site which is of interest, while tourists are more concerned in finding “an unspoilt island”. A historical survey of information about the ancient and the Christian site reveals ambiguities and confusions about both. These multiple meanings for locals and scholars are discussed.     

Identifying wine markers in ceramics and plasters using gas chromatography–mass spectrometry. Experimental and archaeological materials

The identification of the organic residues preserved in archaeological materials yields good insights into understanding food production, trade and consumption. Wine is one of the most important beverages produced, traded and consumed in the Mediterranean area. Consequently, it is important to identify its presence in ancient materials. Nevertheless, the identification of wine markers is still an object of discussion. We present here the results obtained from analysing different materials using gas chromatography/mass spectrometry (GC/MS), which allowed for the identification of tartaric acid and other markers of wine. The method was first tested on experimental and traditional materials that have been used until recently to store and/or produce wine and was then used for investigating archaeological materials. The experiments also involved the degradation of wine through cooking, drastic heating and burial for seven years. The results from the analysis of ceramic and plaster materials are discussed.     

Palynological study of a Mi'kmaw shell midden,Northeast Nova Scotia,Canada

Before now, no palynological studies were made on shell midden deposits in Nova Scotia, despite a long history of archaeological research. A test study of samples taken from the shell midden at Maligomish (Indian Island) on the Northumberland Strait was conducted to determine if sufficient pollen, fern and moss spores, and other non-pollen palynomorphs (NPP's, including fungal remains, algal spores) could be recovered to allow interpretation of environmental conditions at the time of deposition. Several pollen processing methods were tested: sieving and swirling, chemical treatment with cold HCl, 5% KOH and brief exposure to 5% NH₄OH, and treatment with acetolysis solution. We recovered variable amounts of pollen, spores and NPP's from samples taken at 3–5 cm, 5–15 cm and 15–25 cm below surface. Abundant microcharcoal fragments prevented effective use of the swirling technique, but sufficient palynomorphs were recovered by chemical treatments to allow assessment of down-section changes in assemblages. Three radiocarbon ages from Mya arenaria and Crassostrea sp., and measurements of sediment grain size, moisture, organic and inorganic carbon, provide a framework for analysing palynological assemblage changes and context for interpreting differential palynomorph preservation. Despite some oxidation and microbial degradation of palynomorphs in the time interval (ca. 380–1600 cal yr BP), the midden assemblages correlate with pollen zones from marine and lake core sites within ca. 50 km of Maligomish. Shifts in abundances of algal spores, testate amoebae and aquatic plant pollen also indicate changes in depositional conditions during the time of midden use. The study provides the first reference for archaeologists attempting to use palynology for analysis of samples from Nova Scotian shell-bearing contexts.     

Champaner‐Pavagadh Archaeological Park: A Design Approach

Champaner‐Pavagadh, like many other heritage sites in India, is both an historic and ethnographic landscape. It possesses a unique status as a medieval city—Champaner—frozen in time, more or less protected by its sudden abandonment 450 years ago. At the same time, it is a living sacred site—Pavagadh Hill—visited annually by millions, with a resident population. Efforts are underway to declare the hill and the remains of the medieval city at its foot an archaeological park, which will ensure protection and conservation of cultural and natural resources. The challenge in designing the site as an archaeological park lies in articulating the pastoral image conjured up by the term in a manner that does not belie complex issues of land ownership, varied use, and ecological integrity of the site. Working landscapes—farms, flower fields, orchards, and nurseries—can be employed as a landscape‐design typology to ensure sustainability and to preserve and frame sightlines to monuments. Garden archaeology is necessary to uncover the symbiotic relationship between buildings and gardens of medieval Champaner.
