Publicación 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/0000-0002-5449-9287The 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 profilesPublicación Technological variability in El Castillo cave during MIS 4(Springer Nature, 2024-07-29) González Molina, Irene; Maíllo Fernández, José Manuel; Vaquero, Manuel; Neira, Ana; Bernaldo de Quirós, Federico; Marín Hernando, JuanThe variability in Neanderthal behaviour is one of the key debates in Middle Palaeolithic archaeology. Here we present the analysis of the lithic industry from a unit at one of Europe’s main Palaeolithic sites: El Castillo Cave. Unit XXf1.1, dated to the beginning of MIS 4, is an example of human occupation during a period of population decrease. In this assemblage, the technology is organised with the aim of obtaining the largest possible blanks in an environment in which small-sized raw materials predominate, with the presence of imported tools and clear differences in the management of different raw materials. This assemblage is characterized by the predominance of centripetal exploitation methods, and there is only a small number of blanks with laminar tendency, and cleavers. From all this we can observe how Neanderthals were able to find ways to achieve their specific objectives, planning their behaviour to overcome the limitations imposed by the environment.Publicación A step back to move forward: a geological re‐evaluation of the El Castillo Cave Middle Palaeolithic lithostratigraphic units (Cantabria, northern Iberia)(Wiley, 2022-08-28) Martín Perea, David M.; Maíllo Fernández, José Manuel; Marín Hernando, Juan; Arroyo, Xabier; Asiaín, Raquel; https://orcid.org/0000-0002-3238-0904El Castillo Cave is one of the most important sites for understanding the Middle and Upper Palaeolithic in Europe. Despite its importance, the absence of a widely used stratigraphic section with detailed lithostratigraphic descriptions and correlations between the different geological and archaeological interpretations has led to confusion in the correct identification of lithostratigraphic units in the lowermost, Middle Palaeolithic sequence. This study establishes a new lithostratigraphic framework for the site, which can be accurately correlated to previous geological and archaeological studies and generates a solid working basis for framing the Mousterian of El Castillo Cave in the Cantabrian region and southwestern Europe. The geological re‐evaluation of Unit XX (‘Mousterian Alpha’) has expanded its chronology, now ranging from 49 130–43 260 cal BP to 70 400 ± 9600 BP. Unit XXII (‘Mousterian Bet’) would consequently yield an age older than 70 400 ± 9600 BP and younger than the underlying speleothem (Unit XXIIIb), dated to 89 000 +11 000/‐10 000 BP.Publicación The Dorothy Garrod Site: a new Middle Stone Age locality in Olduvai Gorge, Tanzania(Springer Nature, 2022-08-18) Maíllo Fernández, José Manuel; Marín Hernando, Juan; Martín Perea, David Manuel; Uribelarrea, David; Solano Megías, Irene; Asiaín, Raquel; Baquedano, Enrique; Domínguez Rodrigo, Manuel; Gidna, Agness; Medialdea, Alicia; Steven, Hekima Mwamakimbula; Chilonzi, Daniel Haruni; Arteaga, Carlos; Mabulla, Audax; https://orcid.org/0000-0002-3238-0904; https://orcid.org/0000-0002-1681-264X; https://orcid.org/0000-0002-8374-2215; https://orcid.org/0000-0001-5895-0736; https://orcid.org/0000-0001-9591-5497Olduvai Gorge (Tanzania) is a key site for the study of human evolution as well as the origin of modern humans and the Middle Stone Age (MSA). In this study, we present a new MSA location named Dorothy Garrod Site (DGS), found in the main branch of Olduvai Gorge. The site has only one archaeological level, located stratigraphically in the Upper Ndutu. Although it has not yet been possible to radiometrically date it, it has yielded numerous archaeological remains with a functional association between the faunal remains and the lithic industry. The fauna identified includes Alcelaphini, Hippotragini, and Equidae, some of which present percussion marks and evidence of burning. The lithic industry involved knapping using discoid methods. The retouched blanks are denticulates and retouched flakes with, up to now, a total absence of points. DGS is therefore a new site that will aid our understanding of modern human occupations in northern Tanzania in a period for which there is a dearth of properly contextualised archaeological evidence.
