    Identification of age at death in red deer (Cervus elaphus) through the upper dentition: Eruption pattern, wear stage and crown heights
    (Elsevier, 2024-03) Marín Hernando, Juan; Saladié i Ballesté, Palmira; Azorit Casas, Concepción; Rodríguez Hidalgo, Antonio; https://orcid.org/0000-0002-1730-8461; https://orcid.org/0000-0001-9538-7110; https://orcid.org/0000-0002-5449-9287
    The present research aims to determine the age at which red deer (Cervus elaphus) specimens died by examining their upper dentition. We analyzed eighty free-ranging individuals from southern Spain to establish a reference database for age calculation. The age of these individuals was identified by the mandibular teeth inferred from their known death years and the maxillary teeth were evaluated relative to them. As a result, we have provided three non-destructive methods: a description of the eruption sequence and dental replacement, a referential code for occlusal wear stages, and a regression analysis considering the height of the cusps in both upper and lower dentition. These methods offer the possibility of estimating the age at which the animals died and categorizing them into specific age groups. To evaluate the practicality of this method, we applied it to the Middle Paleolithic archaeological site of Abric Romaní. All the proposed methods allow us to approximate the age at death of red deer individuals. The most accurate results, whenever feasible, are obtained by combining these different methods. This study facilitates the inclusion of upper dentition fossils that have traditionally been omitted from the analysis in archaeological sites, allowing a better adjustment of the quantitative methods used to calculate the number of skeletal elements and the number of individuals. This, in turn, enables a more accurate construction of the anatomical and mortality profiles

    Neanderthal hunting strategies inferred from mortality profiles within the Abric Romaní sequence
    (Public Library of Science, 2017-11-22) Marín Hernando, Juan; Saladié Ballesté, Palmira; Rodríguez Hidalgo, Antonio; Carbonell Roura, Eudald; https://orcid.org/0000-0002-1730-8461; https://orcid.org/0000-0002-5449-9287; http://orcid.org/0000-0001-6306-3621
    Ungulate mortality profiles are commonly used to study Neanderthal subsistence strategies. To assess the hunting strategies used by Neanderthals, we studied the ages at death of the cervids and equids found in levels E, H, I, Ja, Jb, K, L and M of the Abric Romaní sequence. These levels date between 43.2 ± 1.1 ka BP (C AMS) and 54.5 ± 1.7 ka BP (U-series). The degree of eruption and development of the teeth and their wear stages were used to determine the ages of these animals at death, and mortality profiles were constructed using these data. The equids display prime dominated profiles in all of the analyzed levels, whereas the cervids display variable profiles. These results suggest that the Neanderthals of Abric Romaní employed both selective and non-selective hunting strategies. The selective strategy focused on the hunting of prime adults and generated prime dominated profiles. On the other hand, non-selective strategies, involved the consumption of animals of variable ages, resulting in catastrophic profiles. It is likely that in the selective hunting events were conducted using selective ambushes in which it was possible to select specific prey animals. On the other hand, encounter hunting or non-selective ambush hunting may have also been used at times, based on the abundances of prey animals and encounter rates. Specific hunting strategies would have been developed accordance with the taxa and the age of the individual to be hunted. The hunting groups most likely employed cooperative hunting techniques, especially in the capture of large animals. Thus, it is not possible to uniquely associate a single mortality profile with the predation tactics of Neanderthals at Abric Romaní.

    Ungulate carcass transport strategies at the Middle Palaeolithic site of Abric Romaní (Capellades, Spain)Stratégies de transport de carcasses d’ongulé au site Paléolithique moyen de l’Abric Romani (Capellades, Espagne)
    (ELSEVIER, 2017) Marín Hernando, Juan; Saladié Ballesté, Palmira; Rodríguez Hidalgo, Antonio; Carbonell Roura, Eudald; https://orcid.org/0000-0002-1730-8461; https://orcid.org/0000-0002-5449-9287; http://orcid.org/0000-0001-6306-3621
    We evaluated the skeletal profiles from several levels of the Neanderthal site of AbricRomaní, focusing on the methodology proposed by Faith and Gordon (2007): differencesin the skeletal distribution of animals in accordance with their size and weight; the sta-tistical correlation between the skeletal profiles and standard food utility index; and theanatomical diversity of size-weight categories. Results indicate an unconstrained transportstrategy in all levels and all size-weight categories. However, we also found differences inthe skeletal distribution of medium-sized and large animals, which may be due to differ-ent transport strategies. These characteristics suggest that the superposition of transportand occupation events could be responsible for our results. In addition, we applied thesame analysis to Hadza assemblages, which revealed similar results to those found at AbricRomaní. The most striking feature of the Hadza assemblages examined is the superpositionof transport events as a result of successive occupation/deposition events. This suggeststhat the transport strategies used by Neanderthals at Abric Romaní are also characterizedby a high degree of diversity in transport decisions.
