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.

Recent studies using geometric morphometrics for taphonomy have yielded interesting results, opening new horizons of research in both archaeological and paleontological sites. Here we present the analysis of tooth pits left by male and female individuals of two different carnivore species (Panthera tigris and Panthera pardus) in order to see if sexual dimorphism influences the morphology of tooth pit marks. In the process, 3D-scanning and applied statistics were used. Based on samples derived from two individuals of different sexes, the present results indicate sexual dimorphism in these felid species to not be a conditioning factor of tooth pit morphology.

The present study has successfully obtained genetic information that allow the identification from direct descendants of Christopher Columbus, dating from 1526 to 1734. This represents the first achievement of this unique objective. The results obtained from the analysed samples, characterized by their significant antiquity, yield exceptional insights into forensic genetics and its newest protocols and methodologies applied to the study of ancient skeletal remains. This work presents the preliminary results of the whole family study using massive parallel sequencing, focusing on the autosomal Single Nucleotide Polymorphism (SNP) and Short Tandem Repeats (STR) markers, including their flanking region sequences, as well as ancestry informative markers (AIMS) of the great-great-grandson of the discoverer. The results of this project pave the way towards the application of new sequencing technologies for the study of genetic evolution, biogeographical origins and forensic identification of historical characters.

The generation of DNA profiles from skeletal remains is a core challenge in forensic genetics, particularly for the identification of missing persons and the resolution of cold cases. Factors such as diagenesis, DNA fragmentation, and the presence of PCR inhibitors severely compromise traditional methodologies, limiting the potential for successful identification. Similarly, in many archaeological studies, the presence of multiple individuals within a single burial site presents a significant challenge for accurate identification. This study shows how the most innovative forensic genetic techniques can be integrated into archaeological research, enabling the identification of individuals through the establishment of familial relationships between remains recovered from an archaeological site. A large-scale SNP assay, Forenseq® Kintelligence HT, has been applied to a familial group dating back to the 16th-17th century, allowing robust kinship calculations and lineage studies, that, in a first stage, lead to the identification of four individuals spanning four generations within the same family.

Este artículo sintetiza la importancia que ha tenido el Cerro de la Mesa (Alcolea de Tajo, Toledo) en el estudio del Bronce Final y de la Edad de Hierro en la meseta central de la Península Ibérica. Dada su posición estratégica en la confluencia entre los ríos Tajo y Huso, se plantearon una serie de prospecciones con georradar para entender el yacimiento en su conjunto y comprender su urbanismo y encaje geográfico. Se concluye el trabajo resumiendo las interpretaciones visuales que se hicieron de los resultados de la geofísica y confirmando, una vez más, la importancia de los estudios interdisciplinares a la hora de proteger el Patrimonio Histórico y Arqueológico.
