The Potential of Mobile 3D Documentation using Video Based Photogrammetry and iPhone 12 ProRecommended by Ying Tung Fung based on reviews by Dominik Hagmann, Sebastian Hageneuer and 1 anonymous reviewer
I am pleased to recommend the paper titled "Towards a Mobile 3D Documentation Solution. Video Based Photogrammetry and iPhone 12 Pro as Fieldwork Documentation Tools" for consideration and publication as a preprint (Paukkonen, 2023). The paper addresses a timely and relevant topic within the field of archaeology and offers valuable insights into the evolving landscape of 3D documentation methods.
The advances in technology over the past decade have brought about significant changes in archaeological documentation practices. This paper makes a valuable contribution by discussing the emergence of affordable equipment suitable for 3D fieldwork documentation. Given the constraints that many archaeologists face with limited resources and tight timeframes, the comparison between photogrammetry based on a video captured by a DJI Osmo Pocket gimbal camera and iPhone 12 Pro LiDAR scans is of great significance.
The research presented in the paper showcases a practical application of these new technologies in the context of a Finnish Early Modern period archaeological project. By comparing the acquisition processes and evaluating the accuracy, precision, ease of use, and time constraints associated with each method, the authors provide a comprehensive assessment of their potential for archaeological fieldwork. This practical approach is a commendable aspect of the paper, as it not only explores the technical aspects but also considers the practical implications for archaeologists on the ground.
Furthermore, the paper appropriately addresses the limitations of these technologies, specifically highlighting their potential inadequacy for projects requiring a higher level of precision, such as Neolithic period excavations. This nuanced perspective adds depth to the discussion and provides a realistic portrayal of the strengths and limitations of the new documentation methods.
In conclusion, the paper offers valuable insights into the future of 3D field documentation for archaeologists. The authors' thorough evaluation and practical approach make this study a valuable resource for researchers, practitioners, and professionals in the field. I believe that this paper would be an excellent addition to PCIArchaeology and would contribute significantly to the ongoing dialogue within the archaeological community.

Faunal remains from the Upper Paleolithic site of Nahal Rahaf 2 in the southern Judean Desert, IsraelNimrod Marom, Dariya Lokshin Gnezdilov, Roee Shafir, Omry Barzilai, Maayan Shemer https://www.biorxiv.org/content/10.1101/2022.05.17.492258v4
New zooarchaeological data from the Upper Palaeolithic site of Nahal Rahaf 2, IsraelRecommended by Ruth Blasco based on reviews by Ana Belén Galán and Joana Gabucio
The Levantine Corridor is considered a crossing point to Eurasia and one of the main areas for detecting population flows (and their associated cultural and economic changes) during the Pleistocene. This area could have been closed during the most arid periods, giving rise to processes of population isolation between Africa and Eurasia and intermittent contact between Eurasian human communities [1,2].
Zooarchaeological studies of the early Upper Palaeolithic assemblages constitute an important source of knowledge about human subsistence, making them central to the debate on modern behaviour. The Early Upper Palaeolithic sequence in the Levant includes two cultural entities – the Early Ahmarian and the Levantine Aurignacian. This latter is dated to 39-33 ka and is considered a local adaptation of the European Aurignacian techno-complex. In this work, the authors present a zooarchaeological study of the Nahal Rahaf 2 (ca. 35 ka) archaeological site in the southern Judean Desert in Israel .
Zooarchaeological data from the early Upper Paleolithic desert regions of the southern Levant are not common due to preservation problems of non-lithic finds. In the case of Nahal Rahaf 2, recent excavation seasons brought to light a stratigraphical sequence composed of very well-preserved archaeological surfaces attributed to the 'Arkov-Divshon' cultural entity, which is associated with the Levantine Aurignacian.
This study shows age-specific caprine (Capra cf. Capra ibex) hunting on prime adults and a generalized procurement of gazelles (Gazella cf. Gazella gazella), which seem to have been selectively transported to the site and processed for within-bone nutrients. An interesting point to note is that the proportion of goats increases along the stratigraphic sequence, which suggests to the authors a specialization in the economy over time that is inversely related to the occupational intensity of use of the site.
It is also noteworthy that the materials represent a large sample compared to previous studies from the Upper Paleolithic of the Judean Desert and Negev.
In summary, this manuscript contributes significantly to the study of both the palaeoenvironment and human subsistence strategies in the Upper Palaeolithic and provides another important reference point for evaluating human hunting adaptations in the arid regions of the southern Levant.

An insight into traditional method of food production in IndiaRecommended by Otis Crandell based on reviews by Antony Borel, Atefeh Shekofteh, Andrea Squitieri, Birgül Ögüt, Atefe Shekofte and 1 anonymous reviewer
This paper  covers an interesting topic in that it presents through ethnography an insight into a traditional method of food production which is gradually declining in use. In addition to preserving traditional knowledge, the ethnographic study of grinding stones has the potential for showing how similar tools may have been used by people in the past, particularly from the same geographic region.

Geometric Morphometric Analysis of Projectile Points from the Southwest United StatesRobert J. Bischoff https://doi.org/10.31235/osf.io/a6wjc
2D Geometric Morphometrics of Projectile Points from the Southwestern United StatesRecommended by Adrian L. Burke based on reviews by James Conolly and 1 anonymous reviewer
Bischoff (2023) is a significant contribution to the growing field of geometric morphometric analysis in stone tool analysis. The subject is projectile points from the southwestern United States. Projectile point typologies or systematics remain an important part of North American archaeology, and in fact these typologies continue to be used primarily as cultural-historical markers. This article looks at projectile point types using a 2D image geometric morphometric analysis as a way of both improving on projectile point types but also testing if these types are in fact based in measurable reality. A total of 164 point outlines are analyzed using Elliptical Fourier, semilandmark and landmark analyses. The author also uses a network analysis to look at possible relationships between projectile point morphologies in space. This is a clever way of working around the predefined distributions of projectile point types, some of which are over 100 years old. Because of the dynamic nature of stone tools in terms of their use, reworking and reuse, this article can also provide solutions for studying the dynamic nature of stone tools. This article therefore also has a wide applicability to other stone tool analyses.

Can growth in captivity alter the calcaneal microanatomy of a wild ungulate?Romain Cottereau, Katia Ortiz, Yann Locatelli, Alexandra Houssaye*, Thomas Cucchi* https://doi.org/10.1101/2022.08.22.504790
Mobility in pigs: A microanatomical perspectiveRecommended by Nimrod Marom based on reviews by Max Price and Ignacio A. Lazagabaster
Pig domestication and husbandry involved complex processes of introduction, introgression, and feralization that challenge our understanding of human/suid interactions in ancient times. This challenge is a constant stimulus for the development of novel methods and techniques to illuminate aspects of early pig husbandry, such as human-induced changes in mobility. Using geometric morphometrics, Harbers et al. (2020) have shown that the calcaneus records a plastic response to reduced mobility and hence to human management. In the present study, Cottereau et al. (2022) explore the possibility that a similar plastic response to different mobility regimes can be observed in the microanatomy of the calcaneus using CT scans. Their research utilizes a sample of calcanei obtained from Mesolithic specimens, and also from recent suids kept in natural habitat, large pen, and stall. Their results suggest that bone microanatomy is more affected by population differences than by mobility patterns, as illustrated by the similarity between Mesolitic boar calcanei and their difference from recent, free wild boar.

SEAHORS: Spatial Exploration of ArcHaeological Objects in R ShinyROYER, Aurélien, DISCAMPS, Emmanuel, PLUTNIAK, Sébastien, THOMAS, Marc https://doi.org/10.5281/zenodo.7957154
Analyzing piece-plotted artifacts just got simpler: A good solution to the wrong problem?Recommended by Reuven Yeshurun based on reviews by Frédéric Santos, Jacqueline Meier and Maayan Lev
Paleolithic archaeologists habitually measure 3-coordinate data for artifacts in their excavations. This was first done manually, and in the last three decades it is usually performed by a total station and associated hardware. While the field recording procedure is quite straightforward, visualizing and analyzing the data are not, often requiring specialized proprietary software or coding expertise. Here, Royer and colleagues (2023) present the SEAHORS application, an elegant solution for the post-excavation analysis of artifact coordinate data that seems to be instantly useful for numerous archaeologists. SEAHORS allows one to import and organize field data (Cartesian coordinates and point description), which often comes in a variety of formats, and to create various density and distribution plots. It is specifically adapted to the needs of archaeologists, is free and accessible, and much simpler to use than many commercial programs. The authors further demonstrate the use of the application in the post-excavation analysis of the Cassenade Paleolithic site (see also Discamps et al., 2019).
While in no way detracting from my appreciation of Royer et al.’s (2023) work, I would like to play the devil’s advocate by asking whether, in the majority of cases, field recording of artifacts in three coordinates is warranted. Royer et al. (2023) regard piece plotting as “…indispensable to propose reliable spatial planimetrical and stratigraphical interpretations” but this assertion does not hold in all (or most) cases, where careful stratigraphic excavation employing thin volumetric units would do just as well.
Moreover, piece-plotting has some serious drawbacks. The recording often slows excavations considerably, beyond what is needed for carefully exposing and documenting the artifacts in their contexts, resulting in smaller horizontal and vertical exposures (e.g., Gilead, 2002). This typically hinders a fuller stratigraphic and contextual understanding of the excavated levels and features. Even worse, the method almost always creates a biased sample of “coordinated artifacts”, in which the most important items for understanding spatial patterns and site-formation processes – the small ones – are underrepresented. Some projects run the danger of treating the coordinated artifacts as bearing more significance than the sieve-recovered items, preferentially studying the former with no real justification. Finally, the coordinated items often go unassigned to a volumetric unit, effectively disconnecting them from other types of data found in the same depositional contexts.
The advantages of piece-plotting may, in some cases, offset the disadvantages. But what I find missing in the general discourse (certainly not in the recommended preprint) is the “theory” behind the seemingly technical act of 3-coordinate recording (Yeshurun, 2022). Being in effect a form of sampling, this practice needs a rethink about where and how to be applied; what depositional contexts justify it, and what the goals are. These questions should determine if all “visible” artifacts are plotted, or just an explicitly defined sample of them (e.g., elongated items above a certain length threshold, which should be more reliable for fabric analysis), or whether the circumstances do not actually justify it. In the latter case, researchers sometimes opt for using “virtual coordinates” within in each spatial unit (typically 0.5x0.5 m), essentially replicating the data that is generated by “real” coordinates and integrating the sieve-recovered items as well. In either case, Royer et al.’s (2023) solution for plotting and visualizing labeled points within intra-site space would indeed be an important addition to the archaeologists’ tool kits.

Transforming the Archaeological Record Into a Digital Playground: a Methodological Analysis of The Living Hill ProjectSamanta Mariotti https://doi.org/10.5281/zenodo.8302563
Gamification of an archaeological park: The Living Hill Project as work-in-progressRecommended by Sebastian Hageneuer based on reviews by Andrew Reinhard, Erik Champion and 1 anonymous reviewer
This paper (2023) describes The Living Hill project dedicated to the archaeological park and fortress of Poggio Imperiale in Poggibonsi, Italy. The project is a collaboration between the Poggibonsi excavation and Entertainment Games App, Ltd. From the start, the project focused on the question of the intended audience rather than on the used technology. It was therefore planned to involve the audience in the creation of the game itself, which was not possible after all due to the covid pandemic. Nevertheless, the game aimed towards a visit experience as close as possible to reality to offer an educational tool through the video game, as it offers more periods than the medieval period showcased in the archaeological park itself.
The game mechanics differ from a walking simulator, or a virtual tour and the player is tasked with returning three lost objects in the virtual game. While the medieval level was based on a 3D scan of the archaeological park, the other two levels were reconstructed based on archaeological material. Currently, only a PC version is working, but the team works on a mobile version as well and teased the possibility that the source code will be made available open source. Lastly, the team also evaluated the game and its perception through surveys, interviews, and focus groups. Although the surveys were only based on 21 persons, the results came back positive overall.
The paper is well-written and follows a consistent structure. The authors clearly define the goals and setting of the project and how they developed and evaluated the game. Although it has be criticized that the game is not playable yet and the size of the questionnaire is too low, the authors clearly replied to the reviews and clarified the situation on both matters. They also attended to nearly all of the reviewers demands and answered them concisely in their response. In my personal opinion, I can fully recommend this paper for publication.
For future works, it is recommended that the authors enlarge their audience for the quesstionaire in order to get more representative results. It it also recommended to make the game available as soon as possible also outside of the archaeological park. I would also like to thank the reviewers for their concise and constructive criticism to this paper as well as for their time.

A meticulous description of archiving research data from a long-running landscape research projectRecommended by Isto Huvila based on reviews by Dominik Hagmann and Iwona Dudek
The paper “A Focus on the Future of our Tiny Piece of the Past: Digital Archiving of a Long-term Multi-participant Regional Project” (Madry et al., 2023) describes practices, challenges and opportunities encountered in digital archiving of a landscape research project running in Burgundy, France for more than 45 years. As an unusually long-running multi-disciplinary undertaking working with a large variety of multi-modal digital and non-digital data, the Burgundy project has lived through the development of documentation and archiving technologies from the 1970s until today and faced many of the challenges relating to data management, preservation and migration.
The major strenght of the paper is that it provides a detailed description of the evolution of digital data archiving practices in the project including considerations about why some approaches were tested and abandoned. This differs from much of the earlier literature where it has been more common to describe individual solutions how digital archiving was either planned or was performed at one point of time. A longitudinal description of what was planned, how and why it has worked or failed so far, as described in the paper, provides important insights in the everyday hurdles and ways forward in digital archiving. As a description of a digital archiving initiative, the paper makes a valuable contribution for the data archiving scholarship as a case description of practices and considerations in one research project. For anyone working with data management in a research project either as a researcher or data manager, the text provides useful advice on important practical matters to consider ahead, during and after the project. The main advice the authors are giving, is to plan and act for data preservation from the beginning of the project rather than doing it afterwards. To succeed in this, it is crucial to be knowledgeable of the key concepts of data management—such as “digital data fixity, redundant backups, paradata, metadata, and appropriate keywords” as the authors underline—including their rationale and practical implications. The paper shows also that when and if unexpected issues raise, it is important to be open for different alternatives, explore ways forward, and in general be flexible.
The paper makes also a timely contribution to the discussion started at the session “Archiving information on archaeological practices and work in the digital environment: workflows, paradata and beyond” at the Computer Applications and Quantitative 2023 conference in Amsterdam where it was first presented. It underlines the importance of understanding and communicating the premises and practices of how data was collected (and made) and used in research for successful digital archiving, and the similar pertinence of documenting digital archiving processes to secure the keeping, preservation and effective reuse of digital archives possible.

The strength of parthood ties. Modelling spatial units and fragmented objects with the TSAR method – Topological Study of Archaeological RefittingSébastien Plutniak https://osf.io/q2e69
A practical computational approach to stratigraphic analysis using conjoinable material culture.Recommended by Hector A. Orengo based on reviews by Robert Bischoff, Matthew Peeples and 1 anonymous reviewer
The paper by Plutniak  presents a new method that uses refitting to help interpret stratigraphy using the topological distribution of conjoinable material culture. This new method opens up new avenues to the archaeological use of network analysis but also to assess the integrity of interpreted excavation layers. Beyond its evident applicability to standard excavation practice, the paper presents a series of characteristics that exemplify archaeological publication best practices and, as someone more versed in computational than in refitting studies I would like to comment upon.
It was no easy task to find adequate reviewers for this paper as it combines techniques and expertise that are not commonly found together in individual researchers. However, Plutniak, with help from three reviewers, particularly M. Peeples, a leading figure in archaeological applications of network science, makes a considerable effort to be accessible to non-specialist archaeologists. The core Topological Study of Archaeological Refitting (TSAR) method is freely accessible as the R package archeofrag, which is available at the Comprehensive R Archive Network (https://CRAN.R-project.org/package=archeofrag) that can be applied without the need to understand all its mathematical, graph theory and coding aspects. Beside these, an online interface including test data has been provided (https://analytics.huma-num.fr/Sebastien.Plutniak/archeofrag/), which aims to ease access to the method to those archaeologists inexperienced with R. Finally, supplementary material showing how to use the package and evaluating its potential through excellent examples is provided as both pdf and Rmw (Sweave) files. This is an important companion for the paper as it allows a better understanding of the methods presented in the paper and its practical application.
The author shows particular care in testing the potential and capabilities of the method. For example, a function is provided “frag.observer.failure” to test the robustness of the edge count method against the TSAR method, which is able to prove that TSAR can deal well with incomplete information. As a further step in this direction both simulated and real field-acquired data are used to test the method which further proves that archeofrag is not only able to quantitatively assess the mixture of excavated layers but to propose meaningful alternatives, which no doubt will add an increased methodological consistency and thoroughness to previous quantitative approaches to material refitting work, even when dealing with very complex stratigraphies.
All in all, this paper makes an important contribution to core archaeological practice through the use of innovative, reproducible and accessible computational methods. I fully endorse it for the conscious and solid methods it presents but also for its adherence to open publication practices. I hope that it can become of standard use in the reconstruction of excavated stratigraphical layers through conjoinable material culture.

The management of symbolic raw materials in the Late Upper Paleolithic of South-Western France: a shell ornaments perspectiveSolange Rigaud, John O’Hara, Laurent Charles, Elena Man-Estier, Patrick Paillet https://doi.org/10.31235/osf.io/z7pqg
Caching up with the study of the procurement of symbolic raw materials in the Upper PalaeolithicRecommended by Beatrice Demarchi based on reviews by Begoña Soler Mayor , Catherine Dupont and Lawrence Straus
The manuscript "The management of symbolic raw materials in the Late Upper Paleolithic of South-Western France: a shell ornaments perspective" by Solange Rigaud and colleagues (Rigaud et al. 2022) is a perfect demonstration that appropriate scientific methodologies can be used effectively in order to enhance the historical value of findings from “old” collections, despite the lack of secure stratigraphic and contextual data. The shell assemblage (n = 377) investigated here (from Rochereil, Dordogne) had been excavated during the first half of the 20th century (Jude 1960) and reported in 1993 (Taborin 1993), but only this recent analysis revealed that it was composed of largely unmodified mollusc shells, most of allochthonous origin. Rigaud et al. interpret this finding as the raw materials used to produce personal ornaments. This is especially significant, because the focus of research has been on the manufacture, use and exchange of personal ornaments in prehistory, much less so on the procurement of the raw materials. As such, the manuscript adds substantially to the growing literature on Magdalenian social networks.
The authors carried out detailed taxonomic analysis based on morphological and morphometric characteristics and identified at least nine different species, including Dentalium sp., Ocenebra erinaceus, Tritia reticulata and T. gibbosula, as well as some bivalve specimens (Mytilus, Glycymeris, Spondylus, Pecten). Most of the species are commonly found in personal ornament assemblages from the Magdalenian, reflecting intentional selection (also shown by the size sorting of some of the taxa), and cultural continuity. However, microscopic examinations revealed securely-identified anthropogenic modifications on a very limited number of specimens: one Glycymeris valve (used as an ochre container), one Cardiidae valve (presence of a groove), one perforated Tritia gibbosula and two perforated Tritia reticulata bearing striations. The authors interpret this combination of anthropogenic vs natural “signals” as signifying that the assemblage represents raw material selected and stored for further processing.
Assessing the provenance and age of the shells is therefore paramount: the shells found at Rochereil belong to species that can be found on both the Atlantic and Mediterranean coasts. Assuming that molluscan taxa distribution in the past is comparable to that for the present day, this implies the exploitation of two catchment areas and long-distance transportation to the site: taking sea-level changes into account, during the Magdalenian the Mediterranean used to lie at a distance of 350 km from Rochereil, and the Atlantic was not significantly closer (~200 km). Importantly, exploitation of fossil shells cannot be discounted on the basis of the data presented here; direct dating of some of the specimens (e.g. by radiocarbon, or amino acid racemisation geochronology) would be beneficial to clarify this issue and in general to improve chronological control on the accumulation of shells. Nonetheless, the authors argue that the closest fossil deposits also lie more than 200 km away from the site, thus the material is allochthonous in origin.
In synthesis, the Rochereil assemblage represents an important step towards a better understanding of the procurement chain and of the production of ornaments during the European Upper Palaeolithic.
