Hacen referencia al arte rupestre de la Región de Murcia, independientemente de su cronología, de manera que constituya una continuación de la recopilación bibliográfica sobre Prehistoria Reciente.

Con respecto a cavidades absolutamente aisladas, y en superficie, a veces sin depósito que lo cubra, aparece material de filiación neolítica (cerámica y utillaje litio pulimentado), lo cual nos indica que no se han vuelto a pisar desde aquella época. ...

These results allow us to complete the population pyramid of a settlement, analyse mortality trends and relate individuals of a particular sex or age-at-death category to possible funerary rituals, lifestyles and/or states of health and disease. In this work, we carry out a paleodemographic analysis of a singular tomb: the chalcolithic burial site of Camino del Molino, Murcia, SE Spain. The tomb hosted 1348 individuals (30.7% non-adults and 69.3% adults) over two contiguous funerary phases, spanning a large part of the third millennium BC, which makes it a reference site for knowledge of the Recent Prehistoric populations. For this purpose, we estimated different paleodemographic parameters (life tables, mortality rates and sex ratios) and compared them to model life tables of preindustrial populations and data from other contemporary p...

Long bones are an excellent alternative for sex estimation when the most dimorphic anatomical parts are not preserved or are highly altered. Here we propose a set of discriminant functions and classification models to estimate the sex of prehistoric individuals using linear discriminant analysis and machine learning approaches. Different osteometric variables were taken from the humeri, ulnae, radii, femurs and tibias of a sample of 109 articulated skeletons buried in the collective tomb of Camino del Molino (Region of Murcia, SE-Spain), dated to the 3rd millennium BC. Sex was estimated based on standard anthropological methods and ancient DNA analysis of a control sample. Fifty-two discriminant functions with prediction thresholds higher than 0.8 on the ROC curve were obtained using independent (22) and combined variables (30). The best LDA models for sex prediction were those based on proximal epiphyseal widths or their combination with other variables, reaching values close to 0.98 on the ROC curve. The random forest-based model obtained an accuracy of 0.94 and confirmed the importance of epiphyseal widths in sex classification. This analysis is more comprehensive than univariate LDA, as it allows for ranking the importance of bones in sex discrimination and considers correlations between long bones rather than treating them as independent observations. In contrast, applying LDA to each bone makes it easier to predict the sex of other coeval collections that do not have such a complete sample. This work aims to overcome the scarcity of methods that can be applied to sex estimation of the large volume of isolated remains from Camino del Molino and for other Mediterranean skeletal series from the Late Prehistory with high biological affinity and that share similar environmental conditions.

These factors affect the microbial community composition and distribution of species in dental plaque, but it is not known how well these patterns are reflected in archaeological dental calculus. In most archaeological studies, a single sample of dental calculus is studied per individual and is assumed to represent the entire oral cavity. However, it is not known if this sampling strategy introduces biases into studies of the ancient oral microbiome. Here, we present the results of a shotgun metagenomic study of a dense sampling of dental calculus from four Chalcolithic individuals from the southeast Iberian peninsula (ca. 4500-5000 BP). Inter-individual differences in microbial composition are found to be much larger than intra-individual differences, indicating that a single sample can indeed represent an individual in most cases. However, there are minor spatial patter...

Itt contains remains of more than 1,300 individuals, in what it seems to be the complete representation of a chalcolithic population of the second half of the third millenium B.C. deposited during a continuous period of approximately 450 years. A small part of this population is accompanied by grave goods that include some metallic elements typical of the bell-beaker horizon. Also dogs accompanyied various burials. The exceptional character of the find and the circumstances of the excavation required the development of a new methodology for this type of excavation.<br><br>Se presentan los resultados preliminares de la excavación de un enterramiento múltiple en cueva que contiene restos de más de 1300 individuos, en lo que parece ser la representación completa de una población calcolítica de la segunda mitad del III milenio a.C. depositada durante un período continuado de unos 350-400 años....
