A multidisciplinary approach to resolve the taxonomy of the historically extinct sea mink (<i>Neogale macrodon</i>) (Maine, USA)

ABSTRACTThis report offers a reanalysis of modified human bones discovered at several prehistoric archeological sites in South Texas. Twenty‐nine human bone artifacts from multiple Late Prehistoric (ad 700–1500) sites were studied. The artifacts were classified (when possible) by age, bone element, and location. Analysis reveals that bones were cut with a groove‐and‐snap technique. Ample postmortem cutmarks were found associated with the groove‐and‐snap method. Several bones display signs of perimortem processing, defleshing, and reduction. One humerus had been fashioned into an omichicahuaztli or musical rasp. Explanations for these artifacts are offered, including ancestor worship, war trophies, or evidence of knowledge of Postclassic Mesoamerican cultural practices.

Prehistoric archaeological site changes and their causes with paleofloods in Southern Shanxi Province, China

Despite numerous studies on the rise and fall of terrestrial megafauna in the late Quaternary, knowledge about marine megafauna from this period remains limited. In this study, we performed radiocarbon dating and partial mitochondrial DNA sequencing from the skeletal remains of three species of small odontocetes (Pacific white-sided dolphins, Dall's porpoises and harbour porpoises) excavated from prehistoric archaeological sites around the Japanese shore dating back to 8500-1000 years ago (ya). Pacific white-sided dolphins that habituated the eastern coast of Hokkaido around 2000 ya belonged to different maternal groups than those from over 5000 ya and today. Furthermore, the species composition excavated from eastern Hokkaido sites varies between 5000 and 2000 ya. These findings suggest two significant population turnovers of small odontocetes on the east coast of Hokkaido, a transitional zone between the coastal area of East Asia and the offshore North Pacific. Notably, the first turnover, occurring between 5000 and 2000 ya, represents the oldest evidence of local population turnovers of marine megafauna during the late Quaternary.

Jordan’s rich archaeological heritage, encapsulating crucial chapters of human history, faces unprecedented threats from both natural and anthropogenic factors. This article elucidates the various challenges besieging Jordan’s historical sites, ranging from climatic alterations to uninhibited urban expansion and intensified agricultural activities. Furthermore, it casts a spotlight on the detrimental impacts of mining activities, underscoring the urgent need for integrated conservation strategies. By fostering a symbiotic relationship between scientific research and practical conservation efforts, we advocate for a proactive approach to safeguard Jordan’s irreplaceable treasures for future generations, thereby fostering sustainable tourism and empowering local communities. The article also posits that community education and the promotion of sustainable tourism stand as vital tools in this pressing endeavour, beckoning a wider appreciation for Jordan’s affluent history and vibrant culture, while ensuring the endurance of its monumental legacy for ensuing generations.In the face of escalating threats for a large number of archaeological sites, fostering international collaboration is paramount. The article explores the potential of forging ties with Polish researchers, who bring a rich background of experience in the meticulous conservation and management of archaeological heritage. By engaging in a vibrant exchange of experiences and knowledge as well as innovative protective methodologies, there is an avenue to enhance the robustness of preservation strategies in place. This collaborative discourse not only promises fresh perspectives and solutions but also opens doors to capacity building through training and educational programmes dedicated to fragile archaeological relicts.

When J.G. Evans’s Land Snails in Archaeology was published in 1972, it established a new understanding of the environmental history of prehistoric archaeological sites in southern Britain and in the process introduced archaeologists to the value of studying assemblages of land snail shells from archaeological deposits. This paper reflects on the impact of the book, reviews developments in the discipline over the intervening half century, and proposes some future directions for the practice of archaeological land-snail analyses.

The Western Liaohe River Basin, rich in prehistoric cultures, is one of the significant origins of Chinese civilization. However, what is the subsistence basis that supports the development of prehistoric cultures in this region? More importantly, which role did agriculture play in the development of various prehistoric cultures? Which factors drive the diachronic evolution in subsistence strategies? These issues are worthy of study. Based on this, we systematically collected zooarchaeological, archaeobotanical, and stable isotope data from various prehistoric archeological cultural sites spanning from the Neolithic Age to the Bronze Age in the Western Liaohe River Basin, attempting to explore their economic characteristics, evolution process as well as driving factor. The study found that in the Western Liaohe River Basin, the cultivation of millet crops may have begun as early as the Xiaohexi cultural period, and domestic pigs and dogs may have occurred in the Xinglongwa cultural period (Xionglongwa and Xionglonggou site respectively). However, during Hongshan cultural period, collection and hunting (cervids) remained the main subsistence strategy. In the Lower Xiajiadian cultural period, millet agriculture and domestic pig breeding replaced gathering and hunting, as the predominant subsistence strategy. This subsistence pattern was also adopted by subsequent Upper Xiajiadian cultural populations, and in some areas, animal husbandry developed during this period. We analyze that the evolution of the subsistence strategies of the prehistoric humans in this region may be related with Holocene climate change. Meanwhile, other factors such as improvements in production technology, population pressure and the environmental impacts they brought may also play a role. This study reveals the evolution process of subsistence strategies of prehistoric cultures in the Western Liaohe River Basin, and is of great significance in understanding the relationship between subsistence evolution of ancient populations and environmental changes in northern China.

The Ajara region holds a significant position on Georgia’s prehistoric territory, boasting important archaeological sites discovered through field excavations along the Black Sea coastline. Recent interdisciplinary research in the villages of Kobuleti and Khutsubani has provided deeper insights into the living conditions, mobility, and primary activities of ancient inhabitants. Particularly noteworthy is the establishment of a series of absolute dates, which addressed a crucial gap in the chronology of Georgia’s prehistoric archaeological sites. As a result of collaborative research efforts involving Georgian and international experts, a comprehensive study of the Khutsubani population was conducted, marking the first such investigation since 1968. This paper presents the overarching conclusions drawn from their collective research endeavors.

Compound specific stable isotope analysis of amino acids (CSIA-AA) is a powerful tool for determining dietary behaviors in complex environments and improving dietary reconstructions. Here, we conducted CSIA-AA on human (n = 32) and animal (n = 13) remains from two prehistoric archaeological sites (Mumun, Imdang) to assess in more detail the dietary sources consumed by prehistoric Korean populations. Results of estimated trophic position (TP) using Δ15NGlx-Phe show that the Imdang individuals consumed aquatic resources, as well as terrestrial resources. Principal component analysis (PCA) using δ13C and δ15N essential amino acid (EAA) values show that the Imdang humans closely cluster with game birds and terrestrial herbivores, whilst the Mumun humans closely cluster with C4 plants. Quantitative estimation by a Bayesian mixing model (MixSIAR) indicates that the Imdang humans derived a large proportion of their proteins from terrestrial animals and marine fish, whereas the main protein sources for the Mumun humans were C4 plants and terrestrial animals. Additionally, the comparison between the EAA and bulk isotope models shows that there is a tendency to overestimate the consumption of plant proteins when using bulk isotopic data. Our CSIA-AA approach reveals that in prehistoric Korea there were clear differences in human diets through time. This study adds to a growing body of literature that demonstrates the potential of CSIA-AA to provide more accurate estimations of protein consumption in mixed diets than previous bulk isotopic studies.

Microbial deterioration as one of the widespread problems in archaeological site museums significantly affects their safety and exhibits. This paper systemically investigated the environments and conditions of microbial outbreaks in the Dadiwan No. F901 site museum, which is a representative archaeological site of prehistoric Yangshao culture. The morphology and harmful characteristics of the outbreak microorganisms were analyzed by microscopic techniques. The ultraviolet resistance of harmful microorganisms was also studied. Combining these findings with the original facilities of the site museum, a scientific and reasonable project was proposed to control and prevent the activity of harmful microorganisms. In addition, a 1% OIT/DCOIT biocide concentration was applied to inhibit microorganism-caused deterioration, in combination with mechanical removal based on laboratory tests and screening in situ. The effectiveness of microbial control was assessed using a portable microscope, ATP bioluminescence assay, and color difference detection. As a long-lasting preventive measure for microbial deterioration, an ultraviolet sterilization system can efficaciously prevent the re-outbreak of microbial deterioration to form a relatively stable dynamic balance for the surroundings of the site. This study is a resultful exploration in terms of microbial control and plays an important role in the sustainable protection of archaeological site museums.

The article provides a comprehensive account of two significant prehistoric archaeological sites located in Adjara - Kobuleti village and Khutsubani, including their history, modern investigations, and findings. The authors highlight that bone remains were not uncovered during the excavation of Stone Age archaeological sites due to the soil'speculiarities. These remains could have shed light on the hunting environment of that era. Stone artifacts provide insight into the lives of ancient hunter-gatherers in our regionThus, a thorough examination of the stone industry is very important. According to this analysis the authors, a fascinating conclusion is drawn regarding the origins of the Western Transcaucasia stone industry. During the early Holocene era, a new method of stone processing and various types of tools emerged within the aforementioned region. This innovative approach was originally developed in the territory of Iran and Iraq. It's a Mlefaatien culture, which comprises of many significant sites. After conducting a techno-typological analysis of the stone complex, it is believed that hand pressure techniques, backed microblades, Kashkashok side-blow blade-flakes, grooved tools etc. emerged in Western Georgia result of the great migration process from Middle East in the beginning of the 10th millennia BC. This view is supported by the complete range of precise dates, which accurately reflect the migrations ways and times of the early migrants. Additional inquiries in this field, conducted in the future, will undoubtedly uncover even more fascinating insights.

Coal has long fueled human civilizations. The history of systematic coal fuel exploitation has been traced back to the late third millennium before present (post-2500 B.P.). Although sporadic combustion of coal for fuel was reported in some prehistoric archaeological sites, evidence for the systematic exploitation of coal for fuel before 2500 B.P. remains lacking. Here, we report comprehensive understanding for the earliest systematic exploitation of coal for fuel at the Jirentaigoukou site in Xinjiang, northwestern China, at ~3600 B.P. The main body of the site witnessed systematic exploitation of bituminous coals, illustrating a complete chaîne opératoire with selective mining, planned storage, and extensive combustion. Our results transform the knowledge of energy history by extending the upper limit of the systematic exploitation of coal for fuel by approximately a millennium, and provide a precedent of energy transition under intense conflict between social demand and environmental deterioration.

The investigation of fires and burning within the archaeological record has a long history, and the applied methods are diverse. There have been several investigations of prehistoric archaeological sites, but Middle Bronze Age contexts (2000–1450 BC) of the Carpathian Basin have not been widely studied beyond studies of ritual burning or warfare. In this paper, we aimed to add further details to this topic in the household context via thin-section soil micromorphology and related phytolith and charred plant matter analysis. The combination of these techniques has been proven to be advantageous due to their high-resolution quality, but phytolith analysis of soil/sediment via thin sections (i.e., in fixed environment) has not been largely explored yet. In this study, these methods were used to investigate various burning events that affected a Middle Bronze Age Vatya house within the tell site of Százhalombatta-Földvár, Hungary. Three types of fire/burning events were investigated. One was related to hearth activity, another one to a presumed ‘cleaning’ of the house, and the last one to the termination of the building. In the first two cases, everyday life was under the microscope; the latter was more enigmatic, and probable intentional destruction was demonstrated.

A previous investigation revealed that shock-fracturing, a form of low-pressure shock metamorphism in quartz grains, can be produced during near-surface atomic airbursts and in cosmic impact structures, most likely at pressures lower than 8 GPa. This discovery implies that similar shock-fracturing may also form in quartz grains exposed to near-surface airbursts by comets and asteroids. Here, we investigate this hypothesis by examining quartz grains in a sedimentary profile from Abu Hureyra, a prehistoric archaeological site in northern Syria. This site was previously proposed to have experienced a nearby, low-altitude cosmic airburst at the onset of the Younger Dryas (~12,800 years ago). The Younger Dryas boundary layer (YDB) at Abu Hureyra has previously been shown to contain a rich assemblage of materials consistent in indicating a cosmic impact. These include anomalously high concentrations of melted micro-spherules displaying increased remanent magnetism; meltglass with low water content indicative of high-temperature melting; nanodiamonds, potentially including lonsdaleite; carbon spherules produced by biomass burning; black carbon or soot; total organic carbon; and abnormally high-temperature melted refractory minerals and elements, including platinum, iridium, chromite, and zircon. To further test this impact hypothesis, we searched for evidence of shocked quartz, a robust, widely accepted indicator of cosmic impacts. We used a comprehensive analytical suite of high-resolution techniques, including transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD), to examine and characterize quartz grains from the YDB layer at Abu Hureyra. Our analyses revealed the presence of quartz grains with sub-planar, sub-parallel, and sub-micron-wide intragranular fractures, most likely produced by mechanical and thermal shock or the combination of both. Furthermore, these fractures are typically filled with amorphous silica (glass), a classic indicator of shock metamorphism. Elemental analyses of the weight percentages of oxygen in the amorphous silica indicate that this could not have formed from the deposition of hydrated silica (e.g., opal and hyalite), which is enhanced in oxygen. Instead, the silica we observed is typically depleted in oxygen, consistent with melting under highly reducing conditions. The shock fractures in quartz grains also display Dauphiné twinning, which sometimes develops during the stress of high temperatures or pressures. This evidence is consistent with the hypothesis that the glass-filled fractures in quartz grains were produced by thermal and mechanical shock during a near-surface cosmic airburst at Abu Hureyra. These glass-filled fractures closely resemble those formed in near-surface atomic airbursts and crater-forming impact events.

This article introduces the results of investigations and surveys from 2006 to 2017 of the group of Suoi Ba archaeological sites in Nhan Co commune, Dak R’Lap district (Dak Nong). The results reveal eight prehistoric archaeological sites in the Suoi Ba area, which are distributed over an area of about 20 hectares, equivalent to the size of an ancient village, and date from 3,500 to 2,000 years BP. In this study, the authors systematize materials, assess historical-cultural values, briefly outline the prehistoric cultural process at Suoi Ba during the late Neolithic and early Metal Age in Dak Nong, and discuss issues related to Suoi Ba relics in a broader context.

The article considers a new approach for determining the functional zones of the prehistoric archaeological sites in Eastern Europe by the method of geochemical indication: the use of mathematical statistics for processing the geochemical data of cultural deposits at archaeological sites, and the identification of groups of interrelated chemical elements and compounds that reflects the processes of natural sedimentation and anthropogenic activity. It makes it possible to separate the lithological and anthropogenic components. This approach is important for the identification of geochemical element groups associated with different functional zones. The reconstructions were conducted at the Neolithic, Early Metal Age, and the Bronze-Early Iron Age sites in Eastern Europe. Abnormal concentrations of the association (P2O5antr, CaOantr and Srantr) in sediments are attributed to zones of accumulation of bone remains. Anomalous concentrations of a group of elements (K2Oantr, Rbantr) in deposits are associated with wood ash and fireplaces, ash residues from ritual activities, and fires. The group of elements (Ba, MnO, Corg) reflects the accumulation of humus and organic remains, and can characterize areas with food residues, skins, and rotten wood. With the help of the distribution of the main lithological elements (SiO2, Al2O3) in sediments, it is possible to reconstruct the paleorelief at the sites.

Abstract The lower Athabasca River basin in northeastern Alberta contains one of the highest known concentrations of prehistoric archaeological sites in the boreal forests of western Canada. This is due to the combination of readily available sources of lithic raw material stone near a major travel corridor, and extensive archaeological survey conducted in advance of oil sands mining. Typological studies have proposed immediate post-glacial occupations that were contemporaneous with, or immediately followed, the catastrophic glacial Lake Agassiz flood through the area at the end of the Pleistocene. Here, we complement the typology age estimates by using stratigraphic relations and infrared stimulated luminescence (IRSL) dating of aeolian material to determine the age of initial human occupation, and reconstruct the environment encountered by early inhabitants of the region. We find that the first occupations in our study area took place near the Pleistocene-Holocene boundary (ca. 11.3 ± 0.8 ka BP), shortly after catastrophic flooding from Lake Agassiz. The post-flood environment was dominated by cold climatic conditions that supported permafrost, presumably during the late Pleistocene, and underwent significant aeolian deposition. Our results indicate that this area represents a portion of the eastern edge of the deglacial corridor into which plants, animals, and humans dispersed following retreat of the Laurentide Ice Sheet.

Using the Mesolithic site of Tudse Hage in the Great Belt of Denmark, this paper proposes a generic stepwise process to create geoarchaeological models that output seamless morphology maps in a GIS. This was achieved using remote sensing databases and the collection of marine geophysical data, above and below the seabed. On the basis of these data, key areas, with sediment sequences representative of the postglacial transgression surfaces, were identified. Core samples were taken for palaeoenvironmental analysis and dating that enabled a reconstruction of the relative sea-level changes. Using this information, palaeogeographic coastline maps of the Kongemose, late Kongemose, Ertebølle, and Neolithic periods in the Tudse Hage area were prepared, and potential hotspots for archaeological sites were proposed. Since their inundation, submerged prehistoric archaeological sites have been, and are, dynamic, with anthropogenic and natural processes affecting their stability and preservation. With the advocation of in situ preservation as a means of managing underwater cultural heritage, predicting where sites have survived these processes, and where they can be found, in advance of subsea development or other anthropogenic exploitation, is essential. Future natural threats to sites preserved in situ were determined through the modelling of seabed currents and sediment erosion.

This paper examines an aspect of a value-based approach to underground built heritage (UBH). A key tool for the manager of any built heritage today is the mapping of its manifold values for different audiences, to inform their management strategy. This paper first reviews an important paradigm shift that has occurred in the humanities and in cultural heritage management, leading to the recognition of the centrality of the worldviews and lived experience of the different members that make up communities. Drawing on a selection of examples from the literature, it then demonstrates how many UBH sites across a wide spectrum of cultures acquired cosmological and cultic value and significance in a way that is qualitatively different to most built heritage sites above ground. The spectrum of challenges that this poses to the UBH site manager is then outlined by reviewing literature on a selection of UBH examples, from prehistoric archaeological sites to living religious sites. Some key guiding principles are proposed for the management of these different scenarios. Culturally sensitive management that respects the existing value systems of local communities is indispensable wherever such communities are present. Decision-makers need to be keenly aware of these value systems and need to recognize, empower, and complement existing traditional systems of stewardship.

BackgroundWildfires 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.ResultsMachine 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.ConclusionsModels 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.
