“…Evidence is mostly represented by find-spots, while only a few sites have been the object of extensive investigations, which have either yielded lithic assemblages only or, have been explored over small surfaces mainly. Overall, this Castelnovian record shows a similar distribution pattern to that of the Early Mesolithic Sauveterrian culture complex, which reflects an intense occupation of both mountainous (central and eastern Alps, Emilian Apennines) and plain areas (Po and interconnected alluvial plains) [16][17][18][19][20]. Consequently, the decline in the occupation intensity of upland territories with a shift towards pre-Alpine and plain areas during the Castelnovian, originally proposed in the 1980s [21,22], has now been called into question by the evidence brought to light in several areas of the central and easternsouthern Alps [16,20,23].…”

A snapshot of Late Mesolithic life through death: An appraisal of the lithic and osseous grave goods from the Castelnovian burial of Mondeval de Sora (Dolomites, Italy)

The Late Mesolithic in Southern Europe is dated to the 7th and the first part of the 6th millennia BCE and is marked by profound changes which are mostly evident in the technical know-how and tool-kit of the last hunter-fisher-gatherer societies. The significance of this phase also relates to the fact that it precedes the Early Neolithic, another period of major transformations of human societies. Nonetheless, the Late Mesolithic still remains a poorly known age in this area. A burial discovered at Mondeval de Sora (Northern Italy) in 1987, represents a unique window into this period. In this paper, we provide a detailed analysis of more than 50 lithic and osseous artifacts associated with this burial. We highlight important contextual data regarding the techno-economic dimension and the notion of personal burial possessions. Based on the association and location of some items, we propose a new interpretation of the social status of this individual and the possible impact of technological innovation on the social organization and symbolic sphere of Late Mesolithic groups.

“…In this fervent and stimulating research framework, the accessibility to new technologies that allow for the fast reconstruction of 3D meshes of archaeological artefacts has resulted in the application of new and powerful means of analysis. Besides the numerous papers that have explored the use of GM analysis to stone artefacts discussed in this paper, the use of 3D technology has also allowed researchers to quantify reduction intensity on cores [e.g., 68 ], accurately measure angles between surfaces of bone and stone tools [e.g., 69 , 70 ], and assess knapping skills with the use of virtual refittings [e.g., 71 , 72 ], among other applications.…”

Practical and technical aspects for the 3D scanning of lithic artefacts using micro-computed tomography techniques and laser light scanners for subsequent geometric morphometric analysis. Introducing the StyroStone protocol

Here, we present a new method to scan a large number of lithic artefacts using three-dimensional scanning technology. Despite the rising use of high-resolution 3D surface scanners in archaeological sciences, no virtual studies have focused on the 3D digitization and analysis of small lithic implements such as bladelets, microblades, and microflakes. This is mostly due to difficulties in creating reliable 3D meshes of these artefacts resulting from several inherent features (i.e., size, translucency, and acute edge angles), which compromise the efficiency of structured light or laser scanners and photogrammetry. Our new protocol StyroStone addresses this problem by proposing a step-by-step procedure relying on the use of micro-computed tomographic technology, which is able to capture the 3D shape of small lithic implements in high detail. We tested a system that enables us to scan hundreds of artefacts together at once within a single scanning session lasting a few hours. As also bigger lithic artefacts (i.e., blades) are present in our sample, this protocol is complemented by a short guide on how to effectively scan such artefacts using a structured light scanner (Artec Space Spider). Furthermore, we estimate the accuracy of our scanning protocol using principal component analysis of 3D Procrustes shape coordinates on a sample of meshes of bladelets obtained with both micro-computed tomography and another scanning device (i.e., Artec Micro). A comprehensive review on the use of 3D geometric morphometrics in lithic analysis and other computer-based approaches is provided in the introductory chapter to show the advantages of improving 3D scanning protocols and increasing the digitization of our prehistoric human heritage.

“…A growing body of 3D refitting studies have also been key in the study of reduction strategies (e.g. Delpiano et al 2019;Delpiano and Peresani 2017;Delpiano, Peresani and Pastoors 2017;Weiss 2015). Functional studies, defined as papers investigating the physical traces of use, are a relatively new and niche development in 3D lithic analysis.…”

With over 200 peer-reviewed papers published over the last 20 years, 3D modelling is no longer a gimmick but an established and increasingly common analytical tool for stone artefact analysis. Laser and structured light scanning, photogrammetry, and CT scanning have all been used to model stone artefacts. These have been combined with a variety of different analytical approaches, from geometric morphometrics to custom reduction indices to digital elevation maps. 3D lithic analyses are increasingly global in scope and studies aim to address an ever-broadening breadth of research topics ranging from testing the functional efficiency of artefacts to assessing the cognitive capabilities of hominid populations. While the impact of the computational revolution on lithic analysis has been reviewed, the impact of 3D modelling on lithic analysis has yet to be comprehensively assessed. This paper presents a review of how 3D modelling in particular has impacted the field of stone artefact analysis. It combines a quantitative bibliometric analysis with a qualitative review to assess just how "revolutionary" 3D modelling has been for lithic analysis. It explores trends in the use of 3D modelling in stone artefact analysis, its impact on the wider lithic analysis field, and methodological, regional and theoretical gaps which future research projects could explore.
