Basalt is a widely used raw material for tool manufacture at prehistoric sites, but a unified methodology for assessing how hominfins used basalt in prehistory is lacking. A comprehensive experimental investigation of basalt tools is, thus, necessary to establish a reliable methodological framework that can be used to explore the functional properties of archaeological basalt assemblages.

The aim of this study is to contribute to the development of a methodological framework for the analysis of use-wear on basalt tools. Basalt, characterised by its distinct mechanical and structural properties and unique response to mechanical stress, requires specialised treatment and investigation.

To address this, our basalt varieties were characterised using SEM–EDS analysis. Sequential experiments were conducted, using the experimental basalt tools in different activities, including butchery, hide, bone and woodworking to determine use-wear formation patterns. Subsequentially, various analytical tools, including optical and scanning electron microscopes, were used to analyse macro- and micro-wear traces on basalt.

Our results provide useful information on methodological aspects of use-wear formation on basalt. The inclusion of detailed cleaning and experimental protocols enhanced the robustness of our methodology. Furthermore, the combined utilisation of various microscopes enabled to compile a comprehensive and complementary information on such a complex raw material such as basalt and to characterise thoroughly the diagnostic features of the micro-wear traces (e.g. edge damage, rounding, polish).

Traditionally, rock engravings were studied through their visual characteristics. They have been analyzed with comparative and interpretative methodologies of iconography and iconology. However, there has been a recent shift towards identifying production processes, allowing reconstruction of operational characteristics through various methods. Nevertheless, the studies of the technological aspects typically focus on the operational and the mechanical, often omitting the visuality of the outcome. In the current paper, we are using ArchCUT3-D software for computational analysis of 3-D data acquired from various rock engravings located in Timna Park, southern Israel. We show how micro-morphological evidence, extracted from the engraved lines, can decode technical trends and variabilities in a technique’s particular implementation. Then, we conduct a focused examination of one group of engraved figures in order to establish a link between execution techniques and visual considerations. Based on our results and the following discussion, we suggest the term Techné to indicate the choice of technique that goes beyond the instrumental or purely operative perspectives. We highlight the intentional choice, which designs the visual rhetoric of the engraved marks and suggests cultural concepts that contrived the procedural processes.

This experimental study aims to contribute to functional analysis research on tools which specifically served to work wood and non-woody plants. They were made of obsidian and other volcanic rocks (basalt, trachyte, and phonolite) characterised by an amorphous matrix and phenocrysts of different number and size. In spite of prior functional analysis research resorting to these raw materials, there remain gaps in our understanding of specific activities. The work thus focused on working different types of wood from the Canary Island as well as on harvesting cereals. It is likewise centred on craftwork, especially regarding certain rarely studied contact materials such as palm leaves and rushes. The results reveal use-wear differences stemming from working woody and non-woody plants with both obsidian and other volcanic rocks. A special attention was given to the identification and description of the different features depending on the raw materials and the characteristics of their knapped surfaces. Identifying the combination of attributes has been essential to attain more accurate diagnostics. There are limits to each of the types of raw materials. The surfaces of obsidian are easier to observe and allow more specific identifications. In turn, the heterogeneous surfaces of volcanic rocks with phenocrysts that require more to time to develop diagnostic traces render use-wear amongst these types of rocks more difficult to observe. It is possible to distinguish longitudinal and transversal actions between woody and non-woody plants on every rock. Actions related to basketry, such us splitting and scraping, are more complicated to identify. The state of the worked plant (dry or fresh) and the time of use are key factors to consider in each case.

One of the main objectives of Palaeolithic art researchers is to study and systematise the form of artistic representations. Some methodologies include the analysis of qualitative variables, linear measurements or the use of geometric morphometry with landmarks. However, these techniques depend to a large extent on the subjectivity of the researcher, which often leads to biased results. To overcome this issue, we present an application of geometric morphometry using Elliptic Fourier Analysis (EFA), together with multivariate statistics and hypothesis testing, for the first time to the study of form in prehistoric art. In order to explain its use, the “duck-bill” convention of pre-Magdalenian horses, often used as a chronological and geographical marker, has been used as a case study. This formalism is described disparately in the literature, so the main objective is to use EFA to determine whether it is possible to characterise this type of convention according to the definitions given by certain authors. The results indicate a possible classification of the heads of these animals. Through this taxonomic proposal, it has been possible to verify the great diversity of forms in which the authors classify the duck-bill horses and, therefore, to demonstrate that this peculiar form can be considered neither a conventionalism nor a chronological/regional marker. In conclusion, the methodology based on EFA combined with multivariate statistics for the objective study of form in prehistoric art is effective and opens a new avenue of analysis in the art of prehistoric societies.

We present a revision of the concept of space in Palaeolithic cave art. Previous research attempting to approach this notion encounters several gaps, which surface on multiple levels: subjectivity, vagueness, restrictions on its conceptualisation, its illustration (two-dimensional description and representation), among others. We reassess the key elements at play, interpretative attempts, and theoretical concepts to gain a better understanding of the notion of space as applied to cave art. This is achieved by examining the historiography not only in prehistory but also in related disciplines, integrating new theoretical approaches and insights from ethnoarchaeology, linguistics, cognitive science, and analytic philosophy. Following this analysis of the existing research, we propose a new method to address the aforementioned issues. This method relies on digital quantitative tools for spatial analysis and three-dimensional representation, such as geographic information systems (GIS) and 3D visualisation. Through the application of these advanced technological tools, we aim to offer a more comprehensive and precise representation of the spatial aspects in Palaeolithic cave art, enabling researchers to analyse and comprehend the complexities of spatial distribution in a systematic and quantitative manner.

There is relative agreement among many prehistorians that surpluses were an essential factor in the creation of socioeconomic inequalities and that storage was often an important aspect of surplus accumulation per Testart (Les chasseurs-cueilleurs ou l’origine des inégalités 1982a), Testart (Current Anthropology, 23, 523–537, 1982b). However, there is little agreement concerning the existence of large-scale kills, storage, surpluses, or inequalities in the deeply incised river valleys of the Southwestern French Upper Paleolithic. We present observations from a number of studies indicating that there were likely large-scale reindeer kills with substantial amounts of meat being filleted, dried, and stored, as well as indications of surpluses that could have resulted in inequalities. We rely on ethnographic observations among the Inuit concerning hunting, butchering, and filleting of meat for drying, as well as on ethnographic patterns of storage, taphonomic observations about bone discard of these activities, the importance of cut marks, and the behavior of reindeer. A critical distinction is made between the treatment of bones from individually killed animals versus the treatment of bones from large-scale kills. We also consider the implications for storage and surpluses of logistical hunting/gathering patterns, relative sedentism, and skeletal indications of heavy reliance on stored meat. On balance, we conclude that these indications favor the existence of mass kills, storage, and surpluses in certain areas of Southwestern France in the Upper Paleolithic.

The open-air Epipalaeolithic (Geometric Kebaran) site of Neve David (Mount Carmel, Israel) has played an important role in reconstructing scenarios of sedentarization in the Levant since its initial excavation in the 1980s, and has been seen as heralding later Natufian socioeconomic adaptations. However, little was known about the site’s formation processes and spatial organization, hindering the testing of this view. Employing new field data from Neve David, we present a combined macro- and microscopic analyses of the spatial and temporal distribution of lithics, faunal remains, phytoliths and wood ash, interpreted with the aid of ethnoarchaeological data and comparison to other Palaeolithic sites in the region. Post-depositional disturbance seems to be minimal at Neve David and we therefore suggest that the spatial distribution of the finds mostly represents human use of space. Throughout the thick sequence of occupation episodes, distinct division of space and well-preserved trampled occupation surfaces are generally lacking. We suggest that this pattern represents reduced mobility, as prolonged human activity blurs the primary depositional signal of the activity remains. The density of the finds generally increases in the upper layers of the site. Accordingly, we hypothesize that at the beginning of activity, the duration of occupation was longer and only later in the sequence of events was there an increase in group size. Our findings further highlight the position of the Geometric Kebaran as a pivotal stage in understanding the gap between the preceding highly mobile societies and the succeeding sedentary and demographically-larger Natufian societies.

The aim of this paper is to present the methodology used to study the megalithic architecture of Menjez’s monuments (Akkar, Lebanon), as part of the MEG-A Project - “First megalith builders in the northern Levant” (2022–2025). Twenty-four monuments have been investigated since 2018. The primary objective is to pioneer a comprehensive understanding of the unique Levantine megalithic building techniques and re-establish the “chaînes opératoires,” by determining the builders’ sequence of actions. This groundbreaking methodology originally developed for Western European megalithic monuments, notably in Brittany, France, has been innovatively applied and customized to suit the Levantine context, specifically focusing on the distinctive basaltic monuments of Menjez and its surrounding areas. By using photogrammetry as a tool, the researchers are able to de-construct the megalithic architecture by analyzing the different components of these monuments. Moreover, it is then possible to describe monoliths according to their place within the monument and their geological and geomorphological features. Our work has led us to consider the symbolic aspect expressed in the megalithic architecture of Menjez. Employing this groundbreaking methodology not only yields concrete answers regarding the typology of these monuments but also dramatically reshapes our perception of their construction. It establishes a precise relative chronology for the various architectural phases and, most significantly, reveals the hidden details of the raw material supply chain.

Abstract

Lime-based materials are found in archaeological contexts across many world regions. The earliest evidence of lime production was discovered in the Levant dating to about 16,000 cal BP. Methods for transforming limestone, shells, and corals into slaked lime varied depending on region, culture, and period. Similarly, the use of lime had an extensive variation of applications such as hafting, plastering, mortars, flooring, plastering skulls, decorating, and making frescos. Each step of the lime production process—from raw materials sourcing to the mixing of finished materials—results in specific archaeological assemblages, each capable of delivering critical insight into the knowledge of the people who created them. Here, we review approaches and methodologies used to analyze each production step, and, specifically, those targeting raw materials selection and firing conditions. For investigating effectively raw materials selection and firing conditions of archaeological lime-based materials, we propose a methodological approach based on the integration of petrography and Fourier transform infrared microscopy (mFTIR) that uses chemical and mineralogical reference libraries prepared using experimental lime produced with provenienced raw materials.

Energetic conditions during storms cause major geomorphological changes in coastal environments and drive taphonomic transformations of coastal archaeological sites. Facing the emerging realities of modern climate change and sea-level rise, archaeologists have justifiably focused on erosional processes and the loss of cultural heritage. However, sedimentologists have long recognized that storm-forcing also involves significant (re)depositional processes and the formation of supratidal features. Geoarchaeological research at partially inundated Native American shell mound sites in Tampa Bay, Florida, integrated topobathymetric aerial LiDAR with sub-surface testing to reconstruct complex site-formation histories. These histories include reworking of cultural deposits by contemporary, recent-historical, and ancient storms, forming archaeological tempestites—sediment deposits that have been scoured from and/or deposited within archaeological contexts by storm-forcing. Using sedimentological, zooarchaeological, and radiometric data, as well as post-storm observations, we present methods for recognizing storm-driven redeposition in coastal-estuarine archaeological contexts and demonstrate the potential of archaeo-tempestites for improving archaeological and paleoenvironmental interpretation. Storm-reworking of estuarine shell mounds on the Florida Gulf Coast produces diagnostic signatures in stratigraphy, granulometry, organic content, and mollusk-composition. Ephemeral ground surfaces and overwashed sand-sheets provide suitable loci for radiometric dating of past storm events (¹⁴C and OSL). We discuss inter- and intra-site variation among regional archaeo-tempestites to better understand late-Holocene ecosystem transfer and the long-term effects of shell-bearing sites on inshore-estuarine ecological conditions. We consider the absorption of energetic forcing as part of the life-history or use-life of shell-bearing features and suggest that a broader study of Indigenous coastal terraforming may aid modern coastal protection and management efforts.
