However, the preservation of cultural heritage is a primary concern. This leads to a dilemma between accessing sample material and obtaining sufficient information for a meaningful analytical outcome. Ideally, sampling a specimen would preserve the object for further macro, micro, and molecular analyses. For palaeoproteomics, a number of minimally invasive sampling approaches have been proposed, representing different benefits and limitations. There have been studies comparing a selection of these protocols, however, these have focused on specimens from a homogenous preservation environment using Zooarchaeology by Mass Spectrometry (ZooMS). Here we expand on earlier work by extending the comparison to specimens from two highly different preservation environments through both ZooMS and liquid-chromatography tandem mass spectrometry (LC-MS/MS). We compare five sampling approaches and seven extraction protocols in total, on 10 <em>Bos</em> sp. humeri from the Early Neolithic site of La Draga, Spain, utilising MALDI-ToF MS and LC-MS/MS to generate proteomic output, while assessing protocol invasiveness using microscopy and 3D imaging. Five humeri originate from Sector A, which is mostly related to dry, terrestrial preservation conditions, while the other five humeri stem from Sector B, which is characterised by its phreatic/aquatic preservation conditions. We show that there is a significant difference in protein recovery and taxonomic specificity between the sampling techniques applied, as well as between burial conditions. Additionally, various surface modifications were observed depending on the specific sampling technique applied. It is therefore essential to assess protein preservation for each sedimentological context within an archaeological site before performing extensive sampling, as protein preservation can be highly inter- and intra-site-specific.</p></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0305440324000700/pdfft?md5=5c14860be2d248108de77e8cd481e41b&pid=1-s2.0-S0305440324000700-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141072983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present a new approach to quantify one aspect of flake scar arrangement on cores: the three-dimensional orientation of core scar negatives. Using standardised digital and experimentally flintknapped cores, we demonstrate that statistical techniques from fabric analysis can quantitatively characterise the scar orientation profile of cores. Importantly, this method is able to reveal variations in the flake scar arrangements of informal cores, such as multiplatform cores. When applied to a sample of multiplatform cores from the <em>Homo floresiensis</em> type-site of Liang Bua in Indonesia, we identify differences in flake scar orientation between cores made by <em>Homo floresiensis</em> and those manufactured by modern humans who utilised the site after the disappearance of the extinct hominin. This finding suggests a possible divergence in stone knapping practices between the two hominin taxa at Liang Bua. Overall, our research provides a new quantitative approach to gain new insights into hominin technological behaviour through stone artefact analysis.

Ancient glue production is considered one of the oldest known highly complex technologies, requiring advanced technological and mental abilities. However, our current knowledge of adhesive materials, recipes, and uses in South Africa is limited by the lack of in-depth analysis and molecular characterization of residues. To deepen our knowledge of past adhesive technology, we performed a detailed multi-analytical analysis (use-wear, XRD, μ-CT, IR spectroscopy, GC-MS) of 30 Later Stone Age tools with adhesive remains from Steenbokfontein Cave, South Africa. At the site, tools made of various rocks were hafted with compound adhesives, and we identified three recipes: 1) resin/tar of <em>Widdringtonia</em> or <em>Podocarpus</em> species combined with hematite; 2) resin/tar of <em>Widdringtonia</em> or <em>Podocarpus</em> species mixed with hematite and another plant exudate; 3) resin/tar without hematite. The studied scrapers were used in hide-working activities, and the studied cutting tools were used to work animal and soft plant matters. All scrapers display evidence of intense resharpening and were discarded when no longer useable. The combination of different methods for residue analysis reveals the flexibility of adhesive technology at Steenbokfontein. Despite the consistent use of conifer resin/tar throughout the sequence, we observed that other ingredients were added or excluded independently of the tools’ raw materials and functions. Our results highlight the long-lasting tradition of using adhesive material from conifer species but also the adaptability and flexibility of adhesive traditions.

We draw on environmental, archaeological and experimental data on the preparation and construction of grass-wrapped clay blocks at the Liangzhu City and investigate the importance of technological innovations to understand architectural energetics and labour organisation behind the unprecedented urbanisation at Liangzhu and beyond in prehistoric Yangtze Delta region. We estimate that each clay block took only around 5 min to prepare by 2–4 workers. Considering digging and other tasks, a small group of 3–4 workers would have been the most efficient arrangement in the preparation of grass-wrapped clay blocks. We reproduced different types of clay blocks, classified their sizes, and identified the standard sized (45x15 × 15cm) clay blocks that match with archaeological finds. Our results also show that standard-sized clay blocks had a more optimal grass-earth ratio which increased the drainage efficiency of the built clay-blocked structures and their resistance to weathering in wet conditions. The different architectural technologies applied by the Liangzhu builders constituted the Liangzhu builders’ earth-building toolkit. To maximize the efficiency, labour was divided and organised according to different construction tasks. The clay-blocked structures and stone beddings were mostly built by smaller groups, who were responsible for the preparation, transportation and construction tasks. Mobilization and division of labour during these construction activities might not follow the classical top-down process. Instead, the need to apply different architectural technologies, each restrained by availability of resources, convenience of transportation, and/or intrinsic engineering properties, at construction sites in a predominantly aquatic environment, prompted a creative form of labour organisation. Our study therefore provides fresh insights into understanding labour organisation, social structure and power relations at the Liangzhu Civilisation.</p></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0305440324000670/pdfft?md5=97ba37c2b37499f870f007c3e3442967&pid=1-s2.0-S0305440324000670-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140919047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing upon the phenomenological Fick's law and microscopic diffusion mechanism, we quantitatively discuss the primary physical parameters that influence the diffusion behaviour for the first time, clarifying that the diffusion of cobalt ions is not related to the medium viscosity. Moreover, compared with the microstructural features of blue decors with and without the bleeding effect, we reveal that domestic cobalt particles are all encapsulated by anorthite crystals, acting as a passivation shell to hinder the dissolution of cobalt particles. Significantly, our reinterpretation has broader archaeological implications for the bleeding effect associated with cobalt pigment in ceramics, elucidating the historical trajectories of responsive practices and the multifaceted interplay between resource form, artistic expression and technological advancement across varying environmental and cultural contexts. Overall, these responses to the bleeding effect exemplify the complexities of technological evolution, highlighting that technology is not merely an extension of technical knowledge but also functions as a form of social construction deeply intertwined with its local context.

This is largely due to a pervasive lack of historical baselines, and highlights the conservation crises affecting some of the world's biodiversity hotspots. In this study, we used otolith metrics and stable isotope analysis to investigate changes in the body length and trophic ecology of several demersal species recovered from pre-colonial (4500 cal BP to 1500 AD) and historical (late 19th and early 20th centuries AD) archaeological sites in Babitonga Bay, the largest mangrove system in southern Brazil. Our results revealed that pre-colonial and historical fisheries exploited a wide range of mangrove habitats, encompassing brackish to marine systems. Pre-colonial subsistence fisheries, however, targeted predominantly small and juvenile individuals in nursery areas, while early commercial fisheries targeted larger adult specimens, likely due to their higher commercial value. Our study shows that some drivers of stock overexploitation, such as the preferential capture of large and adult individuals, were found to be occurring more than 150 years ago along the southern Brazilian coast.

However, age, degree of attrition, and taphonomic factors often make fossil identification difficult. A recent technique for classifying these teeth uses the size-and-shape of the occlusal surface as a summary of the surface, deriving features from this, and then using these features in machine learning classification algorithms. Bovid teeth have previously been classified using this method with features derived from coefficients of elliptical Fourier analysis (EFA). This study assesses the utility of using other shape representations for feature generation, specifically elastics shape analysis. Features were derived using this frame work for both shape only and size-and-shape (i.e. size is not considered a nuisance parameter), and those features were used as input for machine learning algorithms. We demonstrate that features derived elastic shape analysis generally outperform features derived from EFA in terms of cross validation classification accuracy. Finally, an application of the classification methods studied here was applied to fossils recovered from the deroofed Gladysvale External deposit (GVED), Gauteng Province, South Africa. Previous analyses of GVED identified a group of bovids as medium sized alcelaphines (Lacruz et al., 2002). Specifically, this study reclassified 32 unbroken, medium sized alcelaphines looking at shape and size-and-shape.

A thorough literature analysis of recent research is presented, with a special emphasis on vision-based approaches for 3D reconstruction and mapping. First, the paper lists different robotic platforms, various underwater imaging systems and possible combinations among them, through their use in marine archaeological research. In addition to robotic vision systems configurations, a thorough survey on computer vision solutions on image processing, online and offline reconstructions, for both simulation environments and real-world UCH scenarios, is given. The final part of the paper reviews strategies for data acquisition optimization through path planning approaches and highlights how working on synthetic data and simulation environments can enhance the quality of real-world operations. Finally, weaknesses, open issues, and future directions of research in marine robotic vision systems within the documentation of UCH are discussed.</p></div>","PeriodicalId":50254,"journal":{"name":"Journal of Archaeological Science","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2024-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140813757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
