Human populations have been known to develop complex relationships with large carnivore species throughout time, with evidence of both competition and collaboration to obtain resources throughout the Pleistocene. From this perspective, many archaeological and palaeontological sites present evidence of carnivore modifications to bone. In response to this, specialists in the study of microscopic bone surface modifications have resorted to the use of 3D modeling and data science techniques for the inspection of these elements, reaching novel limits for the discerning of carnivore agencies. The present research analyzes the tooth mark variability produced by multiple Iberian wolf individuals, with the aim of studying how captivity may affect the nature of tooth marks left on bone. In addition to this, four different populations of both wild and captive Iberian wolves are also compared for a more in-depth comparison of intra-species variability. This research statistically shows that large canid tooth pits are the least affected by captivity, while tooth scores appear more superficial when produced by captive wolves. The superficial nature of captive wolf tooth scores is additionally seen to correlate with other metric features, thus influencing overall mark morphologies. In light of this, the present study opens a new dialogue on the reasons behind this, advising caution when using tooth scores for carnivore identification and contemplating how elements such as stress may be affecting the wolves under study.

This research focuses on the study of the ruins of a large building known as “El Torreón” (the Tower), belonging to the Ulaca oppidum (Solosancho, Province of Ávila, Spain). Different remote sensing and geophysical approaches have been used to fulfil this objective, providing a better understanding of the building’s functionality in this town, which belongs to the Late Iron Age (ca. 300–50 BCE). In this sense, the outer limits of the ruins have been identified using photogrammetry and convergent drone flights. An additional drone flight was conducted in the surrounding area to find additional data that could be used for more global interpretations. Magnetometry was used to analyze the underground bedrock structure and ground penetrating radar (GPR) was employed to evaluate the internal layout of the ruins. The combination of these digital methodologies (surface and underground) has provided a new perspective for the improved interpretation of “El Torreón” and its characteristics. Research of this type presents additional guidelines for better understanding of the role of this structure with regards to other buildings in the Ulaca oppidum. The results of these studies will additionally allow archaeologists to better plan future interventions while presenting new data that can be used for the interpretation of this archaeological complex on a larger scale.

This work aims at enhancing the current methodologies used for generating as-built CAD models suitable for advanced numerical simulations. To this end, this paper proposes the use of a wearable mobile mapping system that allows one to improve the digitalization stage in terms of flexibility and time required. The noise showed by the resulting point cloud, based on the simultaneous location and mapping (SLAM) solution, demands a post-processing stage that introduces the use of a parameter-free noise reduction filter. This filter improves the quality of the point cloud, allowing for the adjustment of surfaces by means of parametric and non-parametric shapes. These shapes are created by using reverse engineering procedures. The results showed during this investigation highlight a novel application of this sensor: the creation of as-built CAD models for advanced numerical simulations. The results of this investigation are complemented by a valuable contribution with respect to the use of an advanced restoration solution, by means of textile reinforced mortar. To this end, the CAD model is used as the geometrical base for several numerical simulations by means of the finite element method. All this procedure is applied in a construction with structural problems.

Here, we present the first three-dimensional taphonomic analysis of a carnivore-modified assemblage at the anatomical scale of the appendicular skeleton. A sample of ten carcasses composed of two taxa (zebra and wildebeest) consumed by wild lions in the Tarangire National Park (Tanzania) has been used to determine element-specific lion damage patterns. This study presents a novel software for the 3D spatial documentation of bone surface modifications at the anatomical level. Combined with spatial statistics, the present analysis has been able to conclude that despite variable degrees of competition during carcass consumption, lions generate bilateral patterning consisting of substantial damage of proximal ends of stylopodials and zeugopodials, moderate damage of the distal ends of femora and marginal damage of distal ends of humeri and zeugopodials. Of special interest is, specifically, the patterning of tooth marks on shafts according to element, since these are crucial to determine not only the type of carnivore involved in any given bone assemblage, but also the interaction with other agents (namely, hominins, in the past). Lions leave few tooth marks on mid-shaft sections, mostly concentrated on certain sections and orientations of stylopodials and, to a lesser extent, of the proximal tibia. Redundant occurrence of tooth marks on certain bone sections renders them as crucial to attest lion agency in carcass initial consumption. Indirectly, this can also be used to determine whether hominins ever acquired carcasses at lion kills.

Bone surface modifications (BSMs) in faunal assemblages are frequently used to infer past agency and actions of hominins and carnivores, with implications for the emergence of key human behaviours. Patterning of BSMs has mostly been defined as a combination of the intensity of marks per bone portion and sometimes per element. Numerous variables involved in butchery can condition cut mark anatomical distribution, so much so that these variables are widely assumed to be stochastic. Here, we present a new methodological approach using a novel geospatial tool (Ikhnos) which combines the three-dimensional spatial documentation of cut mark patterns with spatial statistics based on wavelets, applied to three experimental and ethnoarchaeological faunal assemblages. We use wavelets to identify patterning of multiple longitudinal series of cut mark distributions on bones, and to establish similarities or differences in patterning within and across different assemblages. This method demonstrates the existence of general and behaviour-specific butchery patterns. It can also be used to effectively assess the proportion of mark clustering that is due to randomness, versus that which is conditioned by the butchery process.

This work presents an approach for the preventive conservation of historical constructions by means of Historical Building Information Modelling (HBIM) strategies. To this end, the methodology exploits the latest advances in inspection protocols, digitalization tools -by means of the novel back-pack mapping systems- as well as wireless monitoring networks. All this information is integrated in the HBIM environment by using ad-hoc families and interoperable communication protocols that allow obtaining a complete knowledge of the conservation status of the site. Additionally, the approach uses key performance indicators in order to evaluate the environmental conditions of the different assets presented in the site. All these features have been validated in one of the most representative heritage buildings in Spain: The General Historical Library of the University of Salamanca.

Geothermal energy is becoming essential to deal with the catastrophic effect of climate change. Although the totality of the Earth’s crust allows the exploitation of shallow geothermal resources, it is important to identify those areas with higher thermal possibilities. In this sense, geophysical prospecting plays a vital role in the recognition and estimation of potential geothermal resources. This research evaluates the geothermal conditions of a certain area located in the center of Spain. The evaluation is mainly based on geological and geophysical studies and, in particular, the Time Domain Electromagnetic Method and the Electrical Resistivity Tomography. Once we analyzed the geology and the historical thermal evidence near the study area, our geophysical results were used to define the geothermal possibilities from a double perspective. In relation to anomalous heat gradient, the identification of a fault and the contact with impermeable granitic materials at the depth of 180 m denotes a potential location for the extraction of groundwater. Regarding the common ground-source heat-pump uses, the analysis has allowed the determination of the most appropriate area for the location of the geothermal well field. Finally, the importance of accurately defining the position of the drillings was confirmed by using software GES-CAL.

Historically wolves and humans have had a conflictive relationship which has driven the wolf to extinction in some areas across Northern America and Europe. The last decades have seen a rise of multiple government programs to protect wolf populations. Nevertheless, these programs have been controversial in rural areas, product of the predation of livestock by carnivores. As a response to such issues, governments have presented large scale economic plans to compensate the respected owners. The current issue lies in the lack of reliable techniques that can be used to detect the predator responsible for livestock predation. This has led to complications when obtaining subsidies, creating conflict between landowners and government officials. The objectives of this study therefore are to provide a new alternative approach to differentiating between tooth marks of different predators responsible for livestock predation. Here we present the use of geometric morphometrics and Machine Learning algorithms to discern between different carnivores through in depth analysis of the tooth marks they leave on bone. These results present high classification rates with up to 100% accuracy in some cases, successfully differentiating between wolves, dogs and fox tooth marks.

This paper is focused on the Middle Paleolithic rock shelter called “Abrigo de San Lázaro”, placed in the Eresma River valley (Segovia, Spain). In this area, a multisource geomatic approach is used. On the one hand, the external envelope of the shelter has been digitalized by the means of an efficient combination between aerial photogrammetry and laser scanning (static and mobile). On the other hand, the ground penetrating radar and the electric tomography were used with the aim of evaluating the inner disposition of the shelter. The combination of both digitalization (external and internal) has allowed for improving the knowledge of the site characteristics that, in turn, will facilitate the future excavation works. The results of these studies allow archaeologists to know new data for a better understanding of the site formation (geology of the site, sedimentary potential, rock shelter dimensions, etc.) and the events that took place in it (knowing its historical evolution, especially the interaction between man and the environment). Additionally, the information obtained from these studies is very useful to plan future excavation works on the site.

Stability of masonry constructions is highly conditioned by the geometric disposition of its elements due to its low tensile strength and great compressive mechanical properties. Under this framework, this paper attempts to evaluate the suitability of a wearable mobile mapping solution, equipped in a backpack and based on the well-known simultaneous location and mapping paradigm, for the structural diagnosis of historical constructions. To evaluate the suitability of this device, the structural analysis obtained is compared with a high precision terrestrial laser scanner, which is considered as ground truth. The Romanesque church of San Pedro (Becerril del Carpio, Spain) was selected as a study case. This construction, initially conceived in the XIIIth century, has experimented in the past a soil settlement promoting the leaning of the north wall, several plastic hinges in its barrel vault and a visible geometrical deformation. The comparison of both techniques was carried out at different levels: i) an evaluation of the time needed to obtain the point cloud of the church; ii) an accuracy assessment based on the comparison of a terrestrial network using artificial spheres as checkpoints and; iii) an evaluation of the discrepancies, in terms of safety factor and collapse topology, found during the advance numerical evaluation of the barrel vault by means of the finite element method. This comparison places this wearable mobile mapping solution as an interesting tool for the creation of advanced numerical simulations to evaluate the structural stability of historical constructions.

The Lower Pleistocene site of Bell's Korongo (BK) in Olduvai Gorge (Tanzania) has been a key site for the study of the origin of human behaviour. The lower archaeological levels of BK are characterized by anthropogenic activity related to the exploitation of megafauna (elephant, hippopotamus, Sivatherium) and smaller game (zebra, wildebeest and antelopes). These remains display a high frequency of cut marks. The exceptional state of preservation of the BK fossil assemblage has allowed a wide range of different analyses that, among other things, detected the use of quartzite in butchering activities through the study of cut marks. Following up previous analyses, this paper presents the study of a series of cut marks from the BK faunal assemblage using a 3D geometric morphometric methodological approach in order to determine the mineralogical properties of the quartzite used at the site. BK cut marks are compared with experimentally produced cut marks using 9 mineralogically different quartzite types from Olduvai Gorge. This comparative analysis provides valuable hints about the exact nature of the raw materials used in butchering activities. The results presented here identify a preferential use of quartzite with a finer granular composition, suggesting that hominin populations were already selecting the best raw materials for their use in specific activities 1.3 Mya.

Olduvai Gorge (Tanzania) is one of the key areas for the study of human origins, given the sheer abundance of archaeological and paleontological sites discovered. Several of these archaeological sites have yielded numerous hominin fossils and traces of their activities, thus offering invaluable insights into the nature and origins of human behavior. Nevertheless, certain taphonomic discussions that have been of great importance for the study of the South African cave sites have remained unnoticed in East Africa. One of these issues revolves around the interpretation of Paranthropus as a common prey of predators. In this paper, we analyze the postcranial remains of OH80, a partial skeleton of a Paranthropus boisei discovered at the BK site (Bell Korongo, Bed II of Olduvai Gorge, Tanzania) in 2010. Some of the specimens of this skeleton have been reported to show surface modifications tentatively associated to the action of carnivores. Here, several pits observed on OH80-12, the Paranthropus boisei femur, were digitally reconstructed and analyzed through geometric morphometrics to determine the nature of the marks. The OH80-12 marks are compared with a modern sample of percussion marks and several carnivore tooth pits, since the action of both agents has previously been identified at the site and can sometimes result in equifinality problems. Alongside already published geometric morphometric tests, here we present a very newly developed approach based on the combination of geometric morphometric data and the training of machine learning algorithms. Both methodologies highlight that OH80 was consumed by carnivores, being a felid the most likely modifying agent.

Developments in methodological approaches to high-resolution morphometrical study of cut-mark morphology further our understanding of butchering activities. Identification of micro-morphological variability between different taphonomical alterations on ancient bone allows detection and comparison of bone-surface modifications and associated taphonomical agents and activities. By taking a geometrical-morphometrical approach, data from 3-D laser-scanning and micro-photogrammetrical models of experimental cut-marks enable statistical analysis to classify and distinguish between cut-marks by bifaces from those by flakes, and, in each case, between marks made by flint from those made by quartzite tools. Analysis of two tool types, each made from two raw materials as independent variables, is a methodological advance in morphometrical studies of experimental cut-marks, which hitherto have tended to focus on the respective parts played by tool types or types of raw material in morphometrical characterization of experimental and archaeological cut-marks.

Leopards have been the focus of taphonomic research due to their capacity to create bone accumulations, prey on some hominin groups or potentially provide scavenging opportunities to early hominins. Some of the variables explored to characterise felids as taphonomic agents have presented problems of equifinality, such as the frequency of tooth marks on long bone shafts or the dimensions of tooth pits and scores. Recently, new methodologies based on microphotogrammetry and geometric morphometrics have been developed for the morphologic analysis of taphonomic marks, such as tooth marks. Through a review of Bob Brain’s neotaphonomic collection, the present study applies these new techniques to reconstruct leopard tooth marks and compare these with tooth marks from lions and spotted hyenas. Along with this, the ratio pit to score, a taphonomic variable previously characterised in lions and spotted hyenas, has been analysed. Results show that tooth marks inflicted by leopards, spotted hyenas and lions can be statistically differentiated based on their morphology. On the other hand, the ratio pit to score inflicted by the leopard is closer to hyenas.

Since the 1980s an intense scientific debate has revolved around the hunting capacities of early hominin populations and the behavioral patterns of carnivores sharing the same ecosystem, and thus competing for the same resources. This debate, commonly known as the hunter-scavenger debate, fostered the emergence of a new research line into the Bone Surface Modifications (BSMs) produced by both taphonomic agents. Throughout the following 20 years, multiple studies concerning the action of carnivores have been developed, with a particular focus on the oldest archaeological sites in East Africa. Recent technological advances applied to taphonomy have provided new insight into carnivore BSMs. A newly developed part of this work relies on Geometric Morphometrics (GMM) studies aimed at discerning carnivore agency through the morphologic characterization of tooth scores and pits. GMM studies have produced promising results, however methodological limitations are still present. This paper presents the first combined application of Machine Learning (ML) algorithms and GMM to the analysis of carnivore tooth marks, generating classification rates of 100% between carnivore species in some cases.

The identification of cut marks and other bone surface modifications (BSM) provides evidence for the emergence of meat-eating in human evolution. This most crucial part of taphonomic analysis of the archaeological human record has been controversial due to highly subjective interpretations of the BSM. Here, we use a sample of 79 trampling and cut marks to compare the accuracy in mark identification on bones by human experts and computer trained algorithms. We demonstrate that deep convolutional neural networks (DCNN) and Support Vector Machines (SVM) can recognize marks with accuracy that far exceeds that of human experts. Automated recognition and analysis of BSM using DCNN can achieve an accuracy of 91% of correct identification of cut and trampling marks versus a much lower accuracy rate (63%) obtained by trained human experts. This success underscores the capability of machine learning algorithms to help resolve controversies in taphonomic research and, more specifically, in the study of bone surface modifications. We envision that the proposed methods can help resolve on-going controversies on the earliest human meat-eating behaviors in Africa and other issues such as the earliest occupation of America.

Taphonomic analyses at Palaeolithic sites contribute to explain the processes through which bone assemblages formed and accumulated, with a particular emphasis on the role played by humans. At most sites, the focus is generally on what agents were responsible for the formation of the assemblage. In this paper, in addition to discussing the zooarchaeological evidence and the taphonomy of La Lluera Cave (Asturias), we put forward a new analytical approach that aims to identify the most frequently used raw materials for the butchery of the animal carcasses found at the site. We analysed the cut-marks by means of three-dimensional reconstruction techniques, showing how they were made with both flint and quartzite. This interpretation is in line with the lithic assemblage found at the site, with both materials amply represented. Our results indicate that butchery practices were not significantly conditioned by, nor did they condition, raw material selection, in contrast with the patterns observed at other Palaeolithic sites.

Recent techniques applied to taphonomy have made advances in our understanding of bone surface modifications. For many years, differences in bone density according to element and variations in animal size have been considered conditioning factors for many taphonomic processes. While several studies highlight how animal size and density affect fracture patterns and bone preservation rates, variations in cut mark morphology are yet to be confronted against these variables. Here, we assess the effect of these variables and their potential effect on cut mark morphology by comparing a considerable amount of cut marks on different anatomical elements of both suids and bovids. Experimentally produced cut mark samples were then digitally reconstructed using a David Laser scanner that allowed the statistical analysis of each cut mark's shape and form. Geometric morphometric analysis using 2D and 3D landmark models were unable to find substantial differences in cut mark morphologies caused by either element type of carcass size.
