    Several digital technologies are nowadays developed and applied to the study of the human fossil record. Here, we present a low-cost hardware implementation of the digital acquisition via photogrammetry, applied to a specimen of paleoanthropological interest: the Neanderthal skull Saccopastore 1. Such implementation has the purpose to semi-automatize the procedures of digital acquisition, by the introduction of an automatically rotating platform users can easily build on their own with minimum costs. We provide all the technical specifications, mostly based on the Arduino UNOℱ microcontroller technology, and evaluate the performance and the resolution of the acquisition by comparing it with the CT-scan of the same specimen through the calculation of their shape differences. In our opinion, the replication of the automatic rotating platform, described in this work, may contribute to the improvement of the digital acquisition processes and may represent, in addition, a useful and affordable tool for both research and dissemination

    Survival to amputation in pre-antibiotic era: a case study from a Longobard necropolis (6th-8th centuries AD)

    Get PDF
    The Longobard necropolis of Povegliano Veronese dates from the 6th to the 8th centuries AD. Among the 164 tombs excavated, the skeleton of an older male shows a well-healed amputated right forearm. The orientation of the forearm fracture suggests an angled cut by a single blow. Reasons why a forearm might be amputated include combat, medical intervention, and judicial punishment. As with other amputation cases reported in literature, this one exhibits both healing and osteoblastic response. We argue that the forelimb stump morphology suggests the use of a prosthesis. Moreover, dental modification of RI2 shows considerable wear and smoothing of the occlusal surface, which points to dental use in attaching the prosthesis to the limb. Other indications of how this individual adjusted to his amputated condition includes a slight change in the orientation of the right glenoid fossa surface, and thinning of right humeral cortical bone. This is a remarkable example in which an older male survived the loss of a forelimb in pre-antibiotic era. We link archaeological remains found in the tomb (buckle and knife) with the biological evidence to show how a combined bioarchaeological approach can provide a clearer interpretation of the life history of an individual

    Conservation and Reassessment of an Overlooked Skeletal Collection Preserved Since 1901 at the Museum of Anthropology “G. Sergi”, Rome

    The osteological investigation of archived and historic skeletal collections can often provide clues to how they were organised and managed, offering key osteobiographical insight into past populations. A small, yet significant, collection of skulls housed at the Museum “Giuseppe Sergi” of the Sapienza University of Rome, remained anonymous prior to a recent reassessment protocol started in 2018. This collection was excavated from a funerary area discovered during the 19th century from the site of Castel Trosino (Ascoli Piceno, Italy). The cemetery was part of an important community during the Longobard domination of Italy, as testified by the richness of the cultural artefacts reported with the burials. The 19 skulls presented in this paper are the only ones available for assessment; all the others were lost shortly after the first excavation. Their importance is related to providing a better understanding of biological evidence of a community that lived in Italy during the Early Middle Ages.Attraverso la chiave di lettura osteobiografica, l'indagine di collezioni scheletriche storiche custodite presso Musei e Soprintendenze puĂČ fornire nuovi indizi per la loro storia degli studi.

    Advances in virtual archaeology. Research, preservation, and dissemination

    Get PDF
    The archaeological and palaeontological record (including human skeletal remains) often bears crack, damage and deformations. The recent rapid development of the diagnostic potentials of “virtual archaeology” has provided innovative tools to manage, study and preserve cultural and natural heritage. These tools include, among others, CT-scans, Laser-scanning, photogrammetry, 3D imaging and rapid prototyping. This approach can contribute to any archaeological context from its discovery to research, preservation, and dissemination. 3D imaging techniques, for instance, substitute physical intervention with a virtual protocol aimed at restoring the original shape of an archaeological item or a fossil specimen. In a similar way, the recovery of digital morphological information can be gathered using data preserved even on a deficient finding through the use of 3D comparative samples. Here we present an extended and updated review about the most innovative protocols applied in virtual archaeology and palaeontology

    Dietary resilience among hunter-gatherers of Tierra del Fuego: Isotopic evidence in a diachronic perspective

    Get PDF
    The native groups of Patagonia have relied on a hunter-gatherer economy well after the first Europeans and North Americans reached this part of the world. The large exploitation of marine mammals (i.e., seals) by such allochthonous groups has had a strong impact on the local ecology in a way that might have forced the natives to adjust their subsistence strategies. Similarly, the introduction of new foods might have changed local diet. These are the premises of our isotopic-based analysis. There is a large set of paleonutritional investigations through isotopic analysis on Fuegians groups, however a systematic exploration of food practices across time in relation to possible pre- and post-contact changes is still lacking. In this paper we investigate dietary variation in hunter-gatherer groups of Tierra del Fuego in a diachronic perspective, through measuring the isotopic ratio of carbon (∂13C) and nitrogen (∂15N) in the bone collagen of human and a selection of terrestrial and marine animal samples. The data obtained reveal an unexpected isotopic uniformity across prehistoric and recent groups, with little variation in both carbon and nitrogen mean values, which we interpret as the possible evidence of resilience among these groups and persistence of subsistence strategies, allowing inferences on the dramatic contraction (and extinction) of Fuegian populations

    Stabbed to death. An osteobiography example of violence among Longobards (Povegliano Veronese, Italy, 6th-8th c CE)

    Get PDF
    Here we report the reconstruction of the osteobiography of an adult male buried in the Longobard cemetery of Povegliano Veronese (Northern Italy, late 6th – early 8th century CE), who shows signs of interpersonal violence. The palaeopathological investigation reveals sharp force traumas on the body of the fourth lumbar vertebra and on two right ribs. The absence of signs of healing or bone remodelling indicates that the defects were perimortem. The injuries probably afected vital organs, leading to death. Further macroscopic observations of the skeleton suggest horseback-riding activity. Strontium isotope data from tooth enamel indicate a non-local origin of the individual. X ray and CT scan acquisition and Scanning Electron Microscopy analyses were performed to investigate the bone defects. His osteobiography was interpreted and contextualised in the complex socio-political scenario of post classical Italy. The results document that he spent his childhood outside the Povegliano Veronese area, that during his life he was likely a horseback rider active in battle, but that his violent death did not happen during warfare/battle. This multi-layered approach, supported by archaeological information, osteological investigation, biomolecular analysis, and virtual imagery, allowed for the extensive reconstruction of an individual's life history

    Strontium and oxygen isotopes as indicators of Longobards mobility in Italy. An investigation at Povegliano Veronese

    Get PDF
    The arrival of the Longobards in Northern Italy in 568 CE marked a period of renewed political stability in the peninsula after the collapse of the Western Roman empire. the trajectory of the spread of Longobards in Italy across the Alps and into the South is known from many literary sources. However, their mobility and residence patterns at a population level remain to be fully understood. Here we present a multi-isotopic analysis (87Sr/86Sr and 18o/16O) of 39 humans and 14 animals buried at the Longobard necropolis of Povegliano Veronese (VR, Italy; 6th—8th century CE), to address mode and tempo of the spread of this population in the peninsula. the geographical location of povegliano Veronese plays a key role: the site lies along the Via Postumia, which was one of the main ancient Roman roads of Northern Italy, representing an important route in post-classical Italy. The integration of isotopic data with the archaeological evidence allowed us to determine the presence of individuals from at least three different regions of origin, building a diachronic map of the dynamics of mobility of this group in northern Italy

    Inside the "African Cattle Complex": Animal Burials in the Holocene Central Sahara

    Get PDF
    Cattle pastoralism is an important trait of African cultures. Ethnographic studies describe the central role played by domestic cattle within many societies, highlighting its social and ideological values well beyond its mere function as 'walking larder'. Historical depth of this African legacy has been repeatedly assessed in an archaeological perspective, mostly emphasizing a continental vision. Nevertheless, in- depth site-specific studies, with a few exceptions, are lacking. Despite the long tradition of a multi-disciplinary approach to the analysis of pastoral systems in Africa, rarely do early and middle Holocene archaeological contexts feature in the same area the combination of settlement, ceremonial and rock art features so as to be multi- dimensionally explored: the Messak plateau in the Libyan central Sahara represents an outstanding exception. Known for its rich Pleistocene occupation and abundant Holocene rock art, the region, through our research, has also shown to preserve the material evidence of a complex ritual dated to the Middle Pastoral (6080-5120 BP or 5200-3800 BC). This was centred on the frequent deposition in stone monuments of disarticulated animal remains, mostly cattle. Animal burials are known also from other African contexts, but regional extent of the phenomenon, state of preservation of monuments, and associated rock art makes the Messak case unique. GIS analysis, excavation data, radiocarbon dating, zooarchaeological and isotopic (Sr, C, O) analyses of animal remains and botanical data are used to explore this highly formalized ritual and lifestyles of a pastoral community in the Holocene Sahara

    Virtual excavation and analysis of the early Neanderthal cranium from Altamura (Italy).

    The online version contains supplementary material available at https://doi.org/10.1038/s42003-023-04644-1.Complete Neanderthal skeletons are almost unique findings. A very well-preserved specimen of this kind was discovered in 1993 in the deepest recesses of a karstic system near the town of Altamura in Southern Italy. We present here a detailed description of the cranium, after we virtually extracted it from the surrounding stalagmites and stalactites. The morphology of the Altamura cranium fits within the Neanderthal variability, though it retains features occurring in more archaic European samples. Some of these features were never observed in Homo neanderthalensis, i.e. in fossil specimens dated between 300 and 40 ka. Considering the U-Th age we previously obtained (>130 ka), the morphology of Altamura suggests that the archaic traits it retains may have been originated by geographic isolation of the early Neanderthal populations from Southern Italy.Depto. de GeodinĂĄmica, EstratigrafĂ­a y PaleontologĂ­aFac. de Ciencias GeolĂłgicasTRUEItalian Ministry of Education, University and Researchpu

    Climatic changes and social transformations in the Near East and North Africa during the ‘long’ 4th millennium BC: A comparative study of environmental and archaeological evidence

    Get PDF
    This paper explores the possible links between rapid climate change (RCC) and social change in the Near East and surrounding regions (Anatolia, central Syria, southern Israel, Mesopotamia, Cyprus and eastern and central Sahara) during the ‘long’ 4th millennium (∌4500–3000) BC. Twenty terrestrial and 20 marine climate proxies are used to identify long-term trends in humidity involving transitions from humid to arid conditions and vice versa. The frequency distribution of episodes of relative aridity across these records is calculated for the period 6300–2000 BC, so that the results may be interpreted in the context of the established arid episodes associated with RCC around 6200 and 2200 BC (the 8.2 and 4.2 kyr events). We identify two distinct episodes of heightened aridity in the early-mid 4th, and late 4th millennium BC. These episodes cluster strongly at 3600–3700 and 3100–3300 BC. There is also evidence of localised aridity spikes in the 5th and 6th millennia BC. These results are used as context for the interpretation of regional and local archaeological records with a particular focus on case studies from western Syria, the middle Euphrates, southern Israel and Cyprus. Interpretation of the records involves the construction of plausible narratives of human–climate interaction informed by concepts of adaptation and resilience from the literature on contemporary (i.e. 21st century) climate change and adaptation. The results are presented alongside well-documented examples of climatically-influenced societal change in the central and eastern Sahara, where detailed geomorphological studies of ancient environments have been undertaken in tandem with archaeological research. While the narratives for the Near East and Eastern Mediterranean remain somewhat speculative, the use of resilience and adaptation frameworks allows for a more nuanced treatment of human–climate interactions and recognises the diversity and context-specificity of human responses to climatic and environmental change. Our results demonstrate that there is a need for more local environmental data to be collected ‘at source’ during archaeological excavations
