Transforming the CIDOC-CRM model into a megalithic monument property graph

Informative description of a project implementing a CIDOC-CRM based native graph database for representing megalithic information

Recommended by based on reviews by 2 anonymous reviewers

The paper “Transforming the CIDOC-CRM model into a megalithic monument property graph” describes an interesting endeavour of developing and implementing a CIDOC-CRM based knowledge graph using a native graph database (Neo4J) to represent megalithic information (Câmara et al. 2023). While there are earlier examples of using native graph databases and CIDOC-CRM in diverse heritage contexts, the present paper is useful addition to the literature as a detailed description of an implementation in the context of megalithic heritage. The paper provides a demonstration of a working implementation, and guidance for future projects. The described project is also documented to an extent that the paper will open up interesting opportunities to compare the approach to previous and forthcoming implementations. The same applies to the knowledge graph and use of CIDOC-CRM in the project.

Readers interested in comparing available technologies and those who are developing their own knowledge graphs might have benefited of a more detailed description of the work in relation to the current state-of-the-art and what the use of a native graph database in the built-heritage contexts implies in practice for heritage documentation beyond that it is possible and it has potentially meaningful performance-related advantages. While also the reasons to rely on using plain CIDOC-CRM instead of extensions could have been discussed in more detail, the approach demonstrates how the plain CIDOC-CRM provides a good starting point to satisfy many heritage documentation needs.

As a whole, the shortcomings relating to positioning the work to the state-of-the-art and reflecting and discussing design choices do not reduce the value of the paper as a valuable case description for those interested in the use of native graph databases and CIDOC-CRM in heritage documentation in general and the documentation of megalithic heritage in particular.

From paper to byte: An interim report on the digital transformation of two thing editions

Revitalising archaeological corpus publications through digitisation – the Corpus der römischen Funde im europäischen Barbaricum and the Conspectus Formarum Terrae Sigillatae Modo Confectae as exemplary cases

Recommended by , ORCID_LOGO and ORCID_LOGO based on reviews by Sebastian Hageneuer and Adéla Sobotkova

The paper entitled “From paper to byte: An interim report on the digital transformation of two thing editions” submitted by Frederic Auth and colleagues discusses how those rich and often meticulously illustrated catalogues of particular find classes that exist in many corners of archaeology can be brought to the cutting edge of contemporary research through digitisation. This paper was first developed for a special conference session convened at the EAA annual meeting in 2021 and is intended for an edited volume on the topic of typology, taxonomy, classification theory, and computational approaches in archaeology.

Auth et al. (2023) begin with outlining the useful notion of the ‘thing-edition’ originally coined by Kerstin Hofmann in the context of her work with the many massive corpora of finds that have characterised, in particular, earlier archaeological knowledge production in Germany (Hofmann et al. 2019; Hofmann 2018). This work critically examines changing trends in the typological characterisation and recording of various find categories, their theoretical foundations or lack thereof and their legacy on contemporary practice. The present contribution focuses on what happens with such corpora when they are integrated into digitisation projects, specifically the efforts by the German Archaeological Institute (DAI), the so-called iDAI.world and in regard to two Roman-era material culture groups, the Corpus der römischen Funde im europäischen Barbaricum (Roman finds from beyond the empire’s borders in eight printed volumes covering thousands of finds of various categories), and the Conspectus Formarum Terrae Sigillatae Modo Confectae (Roman plain ware).

Drawing on Bruno Latour’s (2005) actor-network theory (ANT), Auth et al. discuss and reflect on the challenges met and choices to be made when thing-editions are to be transformed into readily accessible data, that is as linked to open, usable data. The intellectual and infrastructural workload involved in such digitisation projects is not to be underestimated. Here, the contribution by Auth et al. excels in the manner that it does not present the finished product – the fully digitised corpora – but instead offers a glimpse ‘under the hood’ of the digitisation process as an interaction between analogue corpus, research team, and the technologies at hand. These aspects were rarely addressed in the literature, rooted in the 1970s early work (Borillo and Gardin 1974; Gaines 1981), on archaeological computerised databases, focused on technical dimensions (see Rösler 2016 for an exception). Their paper can so also be read in the broader context of heterogeneous computer-assisted knowledge ecologies and ‘mangles of practice’ (see Pickering and Guzik 2009) in which practitioners and technological structures respond to each other’s needs and attempt to cooperate in creative ways. As such, Auth et al.’s considerations not least offer valuable resources for Science and Technology Studies-inspired discussions on the cross-fertilization of archaeological theory, practice and currently emerging material and virtual research infrastructures and can be read in conjunction to Gavin Lucas’ (2022) paper on ‘machine epistemology’ due to appear in the same volume. 

Perhaps more importantly, however, the work by Auth and colleagues (2023) exemplifies the due diligence required in not merely turning a catalogue from paper to digital document but in transforming such catalogues into long-lasting and patently usable repositories of generations of scholars to come. Deploying the Latourian notions of trade-off and recursive reference, Auth et al. first examine the structure, strengths, and weakness of the two corpora before moving on to showing how the freshly digitised versions offer new and alternative ways of analysing the archaeological material at hand, notably through immediate visualisation opportunities, through ceramic form combinations, and relational network diagrams based on the data inherent in the respective thing-editions.

Catalogues including basic descriptions and artefact illustrations exist for most if not all archaeological periods. They constitute an essential backbone of archaeological work as repeated access to primary material is impractical if not impossible. The catalogues addressed by Auth et al. themselves reflect major efforts on behalf of archaeological experts to arrive at clear and operational classifications in a pre-computerised era. The continued and expanded efforts by Auth and colleagues build on these works and clearly demonstrate the enormous analytical potential to make such data not merely more accessible but also more flexibly interoperable. Their paper will therefore be an important reference for future work with similar ambitions facing similar challenges.

Multiproxy analysis exploring patterns of diet and disease in dental calculus and skeletal remains from a 19th century Dutch population

Detection of plant-derived compounds in XIXth c. Dutch dental calculus

Recommended by ORCID_LOGO based on reviews by Mario Zimmerman and 2 anonymous reviewers

The advent of biomolecular methods has certainly increased our overall comprehension of archaeological societies. One of the materials of choice to perform ancient DNA or proteomics analyses is dental calculus[1,2], a mineralised biofilm formed during the life of one individual. Research conducted in the past few decades has demonstrated the potential of dental calculus to retrieve information about past societies health[3–6], diet[7–11], and more recently, as a putative proxy for isotopic analyses[12]. 


Based on a proof-of-concept previously published by their team[13], Bartholdy and collaborators’ paper presents the identification of compounds and their secondary metabolites derived from consumed plants in individuals from a XIXth century rural Dutch archaeological deposit[14]. Sørensen indeed demonstrated that drug intake is recorded in dental calculus, which are mineralised biofilms that can encapsulate drug compounds long after the latter are no longer detectable in blood. The liquid-chromatography coupled to mass spectrometry (LC-MS/MS)-based method developed showed the potential for archaeological applications[13]. 

Bartholdy et al. utilised the developed LC-MS/MS method to 41 buried individuals, most of them bearing pipe notches on their teeth, from the cemetery of the 19th rural settlement of Middenbeemster, the Netherlands. Along with dental calculus sampling and analysis, they undertook the skeletal and dental examination of all of the specimens in order to assess sex, age-at-death, and pathology on the two tissues. The results obtained on the dental calculus of the sampled individuals show probable consumption of tea, coffee and tobacco indicated by the detection of the various plant compounds and associated metabolites (caffeine, nicotine and salicylic acid, amongst others). 

The authors were able to place their results in perspective and propose several interpretations concerning the ingestion of plant-derived products, their survival in dental calculus and the importance of their findings for our overall comprehension of health and habits of the XIXth c. Dutch population. The paper is well-written and accessible to a non-specialist audience, maximising the impact of their study. I personally really enjoyed handling this manuscript that is not only a good piece of scientific literature but also a pleasant read, the reason why I warmly recommend this paper to be accessible through PCI Archaeology.

Dealing with post-excavation data: the Omeka S TiMMA web-database

Managing Archaeological Data with Omeka S

Recommended by ORCID_LOGO based on reviews by Electra Tsaknaki and 1 anonymous reviewer

Managing data in archaeology is a perennial problem. As the adage goes, every day in the field equates to several days in the lab (and beyond). For better or worse, past archaeologists did all their organizing and synthesis manually, by hand, but since the 1970s ways of digitizing data for long term management and analysis have gained increasing attention [1]. It is debatable whether this ever actually made things easier, particularly given the associated problem of sustainable maintenance and accessibility of the data. Many older archaeologists, for instance, still have reels and tapes full of data that now require a new form of archaeology to excavate (see [2] for an unrealized idea on how to solve this).

Today, the options for managing digital archaeological data are limited only by one’s imagination. There are systems built specifically for archaeology, such as Arches [3], Ark [4], Codifi [5], Heurist [6], InTerris Registries [7], OpenAtlas [8], S-Archeo [9], and Wild Note [10], as well as those geared towards museum collections like PastPerfect [11] and CatalogIt [12], among others. There are also mainstream databases that can be adapted to archaeological needs like MS Access [13] and Claris FileMaker [14], as well as various web database apps that function in much the same way (e.g., Caspio [15], dbBee [16], Amazon's Simpledb [17], Sci-Note [18], etc.) — all with their own limitations in size, price, and utility. One could also write the code for specific database needs using pre-built frameworks like those in Ruby-On-Rails [19] or similar languages. And of course, recent advances in machine-learning and AI will undoubtedly bring new solutions in the near future.

But let’s be honest — most archaeologists probably just use Excel. That's partly because, given all the options, it is hard to decide the best tool and whether its worth changing from your current system, especially given few real-world examples in the literature. Bastien Rueff’s new paper [20] is therefore a welcomed presentation on the use of Omeka S [21] to manage data collected for the Timbers in Minoan and Mycenaean Architecture (TiMMA) project. Omeka S is an open-source web-database that is based in PHP and MySQL, and although it was built with the goal of connecting digital cultural heritage collections with other resources online, it has been rarely used in archaeology. Part of the issue is that Omeka Classic was built for use on individual sites, but this has now been scaled-up in Omeka S to accommodate a plurality of sites. 

Some of the strengths of Omeka S include its open-source availability (accessible regardless of budget), the way it links data stored elsewhere on the web (keeping the database itself lean), its ability to import data from common file types, and its multi-lingual support. The latter feature was particularly important to the TiMAA project because it allowed members of the team (ranging from English, Greek, French, and Italian, among others) to enter data into the system in whatever language they felt most comfortable.

However, there are several limitations specific to Omeka S that will limit widespread adoption. Among these, Omeka S apparently lacks the ability to export metadata, auto-fill forms, produce summations or reports, or provide basic statistical analysis. Its internal search capabilities also appear extremely limited. And that is not to mention the barriers typical of any new software, such as onerous technical training, questionable long-term sustainability, or the need for the initial digitization and formatting of data. But given the rather restricted use-case for Omeka S, it appears that this is not a comprehensive tool but one merely for data entry and storage that requires complementary software to carry out common tasks.

As such, Rueff has provided a review of a program that most archaeologists will likely not want or need. But if one was considering adopting Omeka S for a project, then this paper offers critical information for how to go about that. It is a thorough overview of the software package and offers an excellent example of its use in archaeological practice.

Tektite geoarchaeology in mainland Southeast Asia

Tektites as chronological markers: after careful geoarchaeological validation only!

Recommended by ORCID_LOGO and based on reviews by Sheila Mishra, Toshihiro Tada, Mike Morley and 1 anonymous reviewer

Tektites, a naturally occurring glass produced by major cosmic impacts and ejected at long distances, are known from five impacts worldwide [1]. The presence of this impact-generated glass, which can be dated in the same way as a volcanic rock, has been used to date archaeological sites in several regions of the world. This paper by Marwick and colleagues [2] reviews and adds new data on the use and misuse of this specific material as a chronological marker in Australia, East and Southeast Asia, where an impact dated to 0.78 Ma created and widely distributed tektites. This material, found in archaeological excavations in China, Laos, Thaïland, Australia, Borneo, and Vietnam, has been used to date layers containing lithic artifacts, sometimes creating a strong debate about the antiquity of the occupation and lithic production in certain regions.

The review of existing data shows that geomorphological data and stratigraphic integrity can be questioned at many sites that have yielded tektites. The new data provided by this paper for five archaeological sites located in Vietnam confirm that many deposits containing tektites are indeed lag deposits and that these artifacts, thus in secondary position, cannot be considered to date the layer. This study also emphasizes the general lack of other dating methods that would allow comparison with the tektite age. In the Vietnamese archaeological sites presented here, discrepancies between methods, and the presence of historical artifacts, confirm that the layers do not share similar age with the cosmic impact that created the tektites.

Based on this review and these new results, and following previous propositions [3], Marwick and colleagues conclude that, if tektites can be used as chronological markers, one has to prove that they are in situ. They propose that geomorphological assessment of the archaeological layer as primary deposit must first be attained, in addition to several parameters of the tektites themselves (shape, size distribution, chemical composition). Large error can be made by using only tektites to date an archaeological layer, and this material should not be used solely due to risks of high overestimation of the age of the archaeological production.

Parchment Glutamine Index (PQI): A novel method to estimate glutamine deamidation levels in parchment collagen obtained from low-quality MALDI-TOF data

Assessing glutamine deamination in ancient parchment samples

Recommended by based on reviews by Maria Codlin and 3 anonymous reviewers

Data authenticity and approaches to data authentication are crucial issues in ancient protein research. The advent of modern mass spectrometry has enabled the detection of traces of ancient biomolecules contained in fossils, including protein sequences. However, detecting proteins in ancient samples does not equate to demonstrating their endogenous nature: instead, if the mechanisms that drive protein preservation and degradation are understood, then the extent of protein diagenesis can be used for evaluating preservational quality, which in turn may be related to the authenticity of the protein data. 

The post-mortem deamidation of asparaginyl and glutamyl residues is a key degradation reaction, which can be assessed effectively on the basis of mass spectrometry data, and which has accrued a long history of research, both in terms of describing the mechanisms governing the reactions and with regard to the best strategies for assessing and quantifying the extent of glutamine (Gln) and asparagine (Asn) deamidation in ancient samples (Pal Chowdhury et al., 2019; Ramsøe et al., 2021, 2020; Schroeter and Cleland, 2016; Simpson et al., 2016; Solazzo et al., 2014; Welker et al., 2016; Wilson et al., 2012). 

In their paper, Nair and colleagues (2022) build on this wealth of knowledge and present a tool for quantifying the extent of Gln deamidation in parchment. Parchment is a collagen-based material which can yield extraordinary insights into manuscript manufacturing practices in the past, as well as on the daily lives of the people who assembled and used them (“biocodicology”) (Fiddyment et al., 2021, 2019, 2015; Teasdale et al., 2017). Importantly, the extent of deamidation can be directly related to the quality of the parchment produced: rapid direct deamidation of Gln is induced by the liming process, therefore high extents of deamidation are linked to prolonged exposure to the high pH conditions which are typical of liming, thus implying lower-quality parchment.

Nair et al.’s approach focuses on collagen peptides which are typically detected during MALDI-TOF mass spectrometry analyses of parchment and build a simple three-step workflow able to yield an overall index of deamidation for a sample (the parchment glutamine index - PQI) 一 taking into account that different Gln residues degrade at different rates according to their micro-chemical environment. The first step involves pre-processing the MALDI spectra, since Nair et al. are specifically interested in maximising information which can be obtained by low-quality data. The second step builds on well-established methods for quantifying Q → E from MALDI-TOF data by modelling the convoluted isotope distributions (Wilson et al., 2012). Once relative rates of deamidation in selected peptides within a given sample are calculated, the third step uses a mixed effects model to combine the individual deamidation estimates and to obtain an overall estimate of the deamidation for a parchment sample (PQI). 

The PQI can be used effectively for assessing parchment quality, as the authors show for the dataset from Orval Abbey. However, PQI could also have wider applications to the study of processed collagen, which is widely used in the food and pharmaceutical industries. In general, the study by Nair et al. is a welcome addition to a growing body of research on protein diagenesis, which will ultimately improve models for the assessment of the authenticity of biomolecular data in archaeology.

Platforms of Palaeolithic knappers reveal complex linguistic abilities

The means of complexity in a lithic reduction sequence

Recommended by ORCID_LOGO based on reviews by Antony Borel and 1 anonymous reviewer

The paper entitled “Platforms of Palaeolithic knappers reveal complex linguistic abilities” [1] submitted by C. Gaucherel and C. Noûs represents an interesting reflection about the possibilities to detect the human cognitive abilities in relation to the lithic production.

The definition and the study of human cognitive abilities during the Lower Palaeolithic it has always been a complex field of investigation. The relation between the technical skills (lithic production) and the emergence of the linguistic abilities is not easy to investigate due to the difficulty of finding objective data to refer to. The proposition, made by C. Gaucherel and C. Noûs, of a formal grammar of knapping as a method to study the syntactical organisation of the reduction sequences, constitute a new and theoretical useful approach.

In order to effectively and precisely define the gestures linked to a specific reduction sequence, for example that of the handaxes shaping, a very large number of variables should be taken into consideration (morphology and quality of the raw material, experience of the knapper, context, percussion technique, forecast of use of the handaxe, etc.). But since a simplification, that brings more elements than the classic one [2,3] is needed, the “action grammar approach” can be a good instrument to detect the common element in a shaping reduction sequence. Furthermore, one of the advantages of the proposed methodology lies in the fact that the definition of the different STs (Stone Technology) can be done according to the technological specific characteristics to be studied and to the type of instrument produced.

The deconstruction of knapping sequences could help to detect the degree of complexity of the different steps of the reduction sequences also thanks to the identification of the sub-actions types. The increasing/decreasing of complexity is a very complicate concept in lithic technology. Since at the base of the lithic production there are two basic concepts (angle between the striking platform and the debitage surface - convexity of the debitage/façonnage surface) which are simply declined in an increasingly complex way, it is not easy to define uniquely in what exactly consists the increase in complexity. The approach proposed in the paper “Platforms of Palaeolithic knappers reveal complex linguistic abilities” can help to have new evidences, according to the identification of the required cognitive abilities.

The proposed example of formal grammar still needs to be confirmed on archaeological collections, but it is probable that a practical application will allow to further develop the methodology and possibly to highlight additional possibilities of the approach.

Hafted stone and shell tools in the Asia Pacific Region

From Polished Stone Tools to Population Dynamics: Ethnographic Archives as Insights

Recommended by based on reviews by Adrian L. Burke and 1 anonymous reviewer

Most archaeological contexts provide objects without organic materials making them quite silent regarding their hafting techniques and use. This is especially true for the polished stone tools that only thanks to a few discoveries in a wet environment, we can obtain some insights regarding their hafting techniques. Use-wear analysis can also be of some support to get a better picture of these artefacts (e.g. Masclans Latorre 2020), whose typology testifies to an important diversity in European Neolithic contexts that sometimes are well-documented from the chaîne opératoire perspective (see De Labriffe and Thirault dir. 2012). 

The study offered by Chris Buckley (2023) constitutes an important contribution to animating these tools. His work relies on the Asia Pacific region, where he gathered data and mapped more than 300 ethnographic hafted stone and shell tools. This database is available on a webpage  https://www.google.com/maps/d/u/0/viewer?mid=1D_sC7VUtQRuRcCgc9rROVU7ghrdiVAg&ll=-2.458804534247277%2C154.35254980859378&z=6, providing a short description and pictures of some of the items, completed by Supplementary data. 

Thanks to this important record of entire objects, the author presents the different possibilities regarding hafting styles, blade orientations and attachment techniques. The combination of these different characteristics led the author to the introduction of a dynamic typology based on the concept of ‘morphospace’. Eight types have been so identified for the Asia Pacific region. 

The geographical distribution of these types is then presented and questioned, bringing also to the forefront some archaeological findings. An emphasis is made on New Guinea island where documentation is important. We can mention the emblematic work of Anne-Marie and Pierre Pétrequin (1993 and 2020) focused on West Papua, providing one of the most consulted books on stone axes by archaeologists. 

The worthy explanations tested to understand this repartition mobilize archaeological or linguistic data to hypothesise a three waves model of innovations in link with agricultural practices. A discussion on the correlation between material culture and language highlights in the background the need for interdisciplinary to deal finely with these interactions and linkages as has been effectively demonstrated elsewhere (Hermann and Walworth 2020).

To conclude, the convergence between European Neolithic and New Guinea polished stone tools is demonstrated here through ‘morphospace’ comparisons. Thanks to this study, the polished stone tools come alive more than any European archaeological context would allow. The population dynamics investigated through these tools are directly relevant to current scientific issues concerning material culture. This example of convergent evolution is therefore an important key to considering this article as a source of inspiration for the archaeological community.

Zooarchaeological investigation of the Hoabinhian exploitation of reptiles and amphibians in Thailand and Cambodia with a focus on the Yellow-headed tortoise (Indotestudo elongata (Blyth, 1854))

A zooarchaeological perspective on testudine bones from Hoabinhian hunter-gatherer archaeological assemblages in Southeast Asia

Recommended by ORCID_LOGO based on reviews by Noel Amano and Iratxe Boneta

The study of the evolution of the human diet has been a central theme in numerous archaeological and paleoanthropological investigations. By reconstructing diets, researchers gain deeper insights into how humans adapted to their environments. The analysis of animal bones plays a crucial role in extracting dietary information. Most studies involving ancient diets rely heavily on zooarchaeological examinations, which, due to their extensive history, have amassed a wealth of data.

During the Pleistocene–Holocene periods, testudine bones have been commonly found in a multitude of sites. The use of turtles and tortoises as food sources appears to stretch back to the Early Pleistocene [1-4]. More importantly, these small animals play a more significant role within a broader debate. The exploitation of tortoises in the Mediterranean Basin has been examined through the lens of optimal foraging theory and diet breadth models (e.g. [5-10]). According to the diet breadth model, resources are incorporated into diets based on their ranking and influenced by factors such as net return, which in turn depends on caloric value and search/handling costs [11]. Within these theoretical frameworks, tortoises hold a significant position. Their small size and sluggish movement require minimal effort and relatively simple technology for procurement and processing. This aligns with optimal foraging models in which the low handling costs of slow-moving prey compensate for their small size [5-6,9]. Tortoises also offer distinct advantages. They can be easily transported and kept alive, thereby maintaining freshness for deferred consumption [12-14]. For example, historical accounts suggest that Mexican traders recognised tortoises as portable and storable sources of protein and water [15]. Furthermore, tortoises provide non-edible resources, such as shells, which can serve as containers. This possibility has been discussed in the context of Kebara Cave [16] and noted in ethnographic and historical records (e.g. [12]). However, despite these advantages, their slow growth rate might have rendered intensive long-term predation unsustainable.

While tortoises are well-documented in the Southeast Asian archaeological record, zooarchaeological analyses in this region have been limited, particularly concerning prehistoric hunter-gatherer populations that may have relied extensively on inland chelonian taxa. With the present paper Bochaton et al. [17] aim to bridge this gap by conducting an exhaustive zooarchaeological analysis of turtle bone specimens from four Hoabinhian hunter-gatherer archaeological assemblages in Thailand and Cambodia. These assemblages span from the Late Pleistocene to the first half of the Holocene. The authors focus on bones attributed to the yellow-headed tortoise (Indotestudo elongata), which is the most prevalent taxon in the assemblages. The research include osteometric equations to estimate carapace size and explore population structures across various sites. The objective is to uncover human tortoise exploitation strategies in the region, and the results reveal consistent subsistence behaviours across diverse locations, even amidst varying environmental conditions. These final proposals suggest the possibility of cultural similarities across different periods and regions in continental Southeast Asia.

In summary, this paper [17] represents a significant advancement in the realm of zooarchaeological investigations of small prey within prehistoric communities in the region. While certain approaches and issues may require further refinement, they serve as a comprehensive and commendable foundation for assessing human hunting adaptations.

A way to break bones? The weight of intuitiveness

Breaking bones: Nature or Culture?

Recommended by and based on reviews by Terry O'Connor, Alan Outram and 1 anonymous reviewer

The nature of breaking long bones for obtaining marrow is important in Paleolithic archaeology, due to its widespread, almost universal, character. Provided that hammer-stone percussion marks can be correctly identified using experimental datasets (e.g., [1]), the anatomical location and count of the marks may be taken to reflect recurrent “cultural” traditions in the Paleolithic [2]. Were MP humans breaking bones intuitively or did they abide by a strict “protocol”, and, if the latter, was this protocol optimized for marrow retrieval or geared towards another, less obvious goal?
The new preprint by Vettese and colleagues [3] took a novel approach to this question, by conducting an experiment which involved novice butchers, relying on nothing but their intuition, and recording the way in which they broke marrow-rich bones. Some variability was noted in the “intuitive” patterns; indeed, future studies replicating this experiment and adding more variables such as more experienced butchers and non-bovid bones are warranted. Similarities in the means by which novice butchers break bones was also observed, and especially telling is the strong effect of anatomical features in most bones, except for the femur.

This paper provides a baseline for location analyses of percussion marks. Their dataset may therefore be regarded as a null hypothesis according to which the archaeological data could be tested. If Paleolithic patterns of percussion marks differ from Vettese et al.’s [3] “intuitive” patterns, then the null hypothesis is disproved and one can argue in favor of a learned pattern. The latter can be a result of ”culture”, as Vettese et al. [3] phrase it, in the sense of nonrandom action that draws on transmitted knowledge. Such comparisons bear a great potential for understanding the degree of technological behavior in the Paleolithic by factoring out the “natural” constraints of bone breakage patterns. Vettese et al. [3: fig. 14] started this discourse by comparing their experimental dataset to some Middle and Upper Paleolithic faunas; we are confident that many other studies will follow.
