Organic Remains

Examples of wetland deposits can be found across the globe and are known for preserving organic archaeological and environmental remains that are vitally important to our understanding of past human–environment interactions. The Mesolithic site of Star Carr (Yorkshire, United Kingdom) represents one of the most influential archives of human response to the changing climate at the end of the last glacial in Northern Europe. A hallmark of the site since its discovery in 1948 has been the exceptional preservation of its organic remains. Disturbingly, recent excavations have suggested that the geochemistry of the site is no longer conducive to such remarkable survival of organic archaeological and environmental materials. Microcosm (laboratory-based) burial experiments have been undertaken, alongside analysis of artifacts excavated from the site, to assess the effect of these geochemical changes on the remaining archaeological material. By applying a suite of macroscopic and molecular analyses, we demonstrate that the geochemical changes at Star Carr are contributing to the inexorable and rapid loss of valuable archaeological and paleoenvironmental information. Our findings have global implications for other wetland sites, particularly archaeological sites preserved in situ.

The City

In this article I focus on the emotional, sensory and aesthetic affordances of urban archaeological remains conserved in situ and explore what these ruins ‘do’ in the context of the layered urban fabric of the city. I am concerned with a particular category of archaeological remains: those that illustrate the colonial history of settler nations, exploring examples in Sydney and Montreal. Using Sara Ahmed’s concept of ‘affective economies’ – where emotions work to stick things together and align individuals with communities – I tease out some of the distinctive aspects of this particular form of social/emotional/material entanglement, that appears to create stable objects of memory and identity from a much more contingent and complex matrix of politics, social structures, and the more-than-human materiality of the city. I argue that an understanding of the affective qualities of ruins and archaeological traces, and of how people feel heritage and the past through aesthetic and sensuous experiences of materiality, authenticity, locality and identity, bring us closer to understanding how heritage works.

Power Tools

In situ protection and conservation of the Underwater Cultural Heritage are now considered a primary choice by the scientific community to be preferred, when possible, over the practice of recovery. The conservation of the artefacts within their environmental context is essential in fact for a correct interpretation of archaeological presences and to preserve their true value intact for future generations. However, this is not an easy task because modern technological equipment is necessary to make the work carried out by underwater restorers and archaeologists faster and more efficient. To this end, the paper presents three innovative underwater power tools for the cleaning, conservation, and consolidation activities to be performed in submerged archaeological sites. The first one is an underwater cleaning brush tool for a soft cleaning of the underwater archaeological structures and artefacts; the second one is a multifunctional underwater hammer drill suitable to be used as a corer sampler, chisel, or drill; the last one is an injection tool specifically designed to dispense mortar underwater for consolidation techniques of submerged structures.

<p>Reflectance spectroscopy is widely used to rapidly and quantitatively determine soil properties. This study introduces a method to identify archaeological soils, which are soils influenced by ancient anthropogenic activities, from the surrounding landscape using a portable VIS-NIR reflectance spectrometer. To identify spectral features of archaeological soils, the method statistically calculates the difference between an archaeological soil spectrum and a non-archaeological soil spectrum. Such difference is quantified by an R-value. Any soil spectra with R-values larger than 1 are more likely to be anthropogenically-affected soils.</p><p>Previously, the method was successfully applied to several archaeological sites in Italy and Hungary showing clear differences between the archaeological and non-archaeological soils. In this study, we will investigate the R-values for soils from prehistoric settlement sites in Sintanjin, Korea, and compare these to the results from Italy and Hungary. Both in-situ and topsoil spectral measurements were gathered using a portable ASD spectrometer. In this site, soils from kitchen areas showed R-values between 2.5 and 4.2, while soils from graves ranged from 1 to 1.4. The results indicate that the R-values vary a lot depending on the type of archaeological remains and a more detailed investigation of the method to various archaeological remains is essential to improve the method. One of our interesting results is that the method can be applied to soil spectra gathered with low-resolution spectrometers which leads to the possibility of applying continuous 2D spectral imaging applications.</p>

AbstractIn recent years, with the participation of genetics and other disciplines, the controversy on the origins of the domestic chicken has returned. As the resource of primary data, archaeology plays an extremely important role in this dispute. Taking an archaeological standpoint, this paper aims to establish a set of bone morphological identification standards for domestic chicken bones unearthed at archaeological remains, beginning with the bone morphology as the most basic but also the least studied aspect. By this set of standards, we reanalyze available chicken bone materials and relevant pictorial and textual materials for domestic chicken candidate samples as mentioned by previous scholars. The results show that no confirmed domestic chicken bones have been found in China’s early to mid-Holocene remains to date; meanwhile, there is no substantial archaeological evidence to support China as the earliest place of origin of domestic chicken. Future work seeking to advance research on the origin of the domestic chicken should first pay proper attention to the archaeological background; only continuing scientific analyses and exploration on the origin of domestic chicken based on scientific morphological identification will prove the most convincing methodology.

Coastal archaeological sites that lack organic remains for radiocarbon dating are often abundant sources of molluscan shells. As a substitute for materials such as bone and charcoal, shells can be analyzed with 14C dating to determine a site's age. Despite their being convenient, non-mobile archaeological artifacts, molluscan shells are plagued by several issues, including carbonate remodeling, in which aragonite in shells is converted to calcite as predicted by thermodynamics. We present here a carbonate density separation technique that addresses the issue of carbonate remodeling. Using a density fractionation with bromoform, aragonite concentrations are enriched in shells that have undergone significant remodeling. The technique has been applied to archaeological shells and has returned dates that are younger than those previously determined for the same shells.

Abstract Background Wildfires of uncharacteristic severity, a consequence of climate changes and accumulated fuels, can cause amplified or novel impacts to archaeological resources. The archaeological record includes physical features associated with human activity; these exist within ecological landscapes and provide a unique long-term perspective on human–environment interactions. The potential for fire-caused damage to archaeological materials is of major concern because these resources are irreplaceable and non-renewable, have social or religious significance for living peoples, and are protected by an extensive body of legislation. Although previous studies have modeled ecological burn severity as a function of environmental setting and climate, the fidelity of these variables as predictors of archaeological fire effects has not been evaluated. This study, focused on prehistoric archaeological sites in a fire-prone and archaeologically rich landscape in the Jemez Mountains of New Mexico, USA, identified the environmental and climate variables that best predict observed fire severity and fire effects to archaeological features and artifacts. Results Machine learning models (Random Forest) indicate that topography and variables related to pre-fire weather and fuel condition are important predictors of fire effects and severity at archaeological sites. Fire effects were more likely to be present when fire-season weather was warmer and drier than average and within sites located in sloped, treed settings. Topographic predictors were highly important for distinguishing unburned, moderate, and high site burn severity as classified in post-fire archaeological assessments. High-severity impacts were more likely at archaeological sites with southern orientation or on warmer, steeper, slopes with less accumulated surface moisture, likely associated with lower fuel moistures and high potential for spreading fire. Conclusions Models for predicting where and when fires may negatively affect the archaeological record can be used to prioritize fuel treatments, inform fire management plans, and guide post-fire rehabilitation efforts, thus aiding in cultural resource preservation.

Ostrich Eggshell

The Neolithic site KS043, excavated by the Institut français d'archéologie orientale (IFAO), is situated in the southern basin of the Kharga Oasis (Egypt). It is one of the very few stratified prehistoric sites of the eastern Sahara. The archaeological remains were found near artesian springs that provided water for pastoralists during the dry Middle Holocene. In situ settlement features provided well-preserved material (charcoal, ashy sediment, ostrich eggshell) sufficient to perform radiocarbon dating in the IFAO laboratory in Cairo by the conventional liquid scintillation method. In 2 cases, ostrich eggshell and charcoal within the same in situ context gave significantly different results of, respectively, ∼600 and ∼1200 yr younger dates for the ostrich eggshells. The strong discrepancy is here highlighted for the first time and we suggest that it may be linked with postdepositional phenomena in the vicinity of the artesian springs. A thorough review of 14C dates available for the Holocene in eastern Sahara shows that ostrich eggshells have been widely used. They seem slightly more prone to be discarded than other material but were never the object of a particular study in this context. Bayesian modeling shows that the Neolithic occupation at site KS043 spans a range from 5000 to 3950 cal BC (and concentrated around 4600–4350 cal BC). Characteristic flint tools and pottery relate this occupation to the end of the Neolithic and show links with the Tasian culture, confirming the timing of the presence of this cultural complex in the desert before its appearance in the Nile Valley.

An isolated human cranium, dated to the early Eneolithic period, was discovered in 2015 at the top of a vertical shaft in the natural Marcel Loubens gypsum Cave (Bologna area, northern Italy). No other anthropological or archaeological remains were found inside the cave. In other caves of the same area anthropic and funerary use are attested from prehistory to more recent periods. We focused on investigating the circumstances surrounding the death of this individual, since the cranium shows signs of some lesions that appear to be the results of a perimortem manipulation probably carried out to remove soft tissues. Anthropological analyses revealed that the cranium belonged to a young woman. We analysed the taphonomic features and geological context to understand how and why the cranium ended up (accidentally or intentionally) in the cave. The analyses of both the sediments accumulated inside the cranium and the incrustations and pigmentation covering its outer surface suggested that it fell into the cave, drawn by a flow of water and mud, likely from the edges of a doline. The accidental nature of the event is also seemingly confirmed by some post-mortem lesions on the cranium. The comparison with other Eneolithic archaeological sites in northern Italy made it possible to interpret the find as likely being from a funerary or ritual context, in which corpse dismemberment (in particular the displacement of crania) was practiced.
