During the Upper Paleolithic, marine resources have traditionally been considered to be low-efficiency resources. However, in recent years, new data have emerged to demonstrate that their importance for human utilization was probably greater than previously thought. The assessment of their value has generally been from the perspective of their nutritional or ornamental value, not from the technological potential that these resources might have. A use-wear analysis of shells from the Gravettian levels of Fuente del Salín, a cave in northern Spain, has documented their use for a diverse range of production activities, most notably the processing of the red pigments used in artistic representations on the cave walls, as well as for tanning hide. This technological use of shells demonstrates that marine resources were of greater importance to the hunters and gatherers of the Upper Paleolithic and that their utility was more diverse than previously understood.

The role played by the Magdalenian site of El Horno in the context of the Asón river basin (northern Spain) is considered in relation to its location and the physical characteristics of the surrounding area. This information has been integrated with data from the archaeological study. Special attention has been paid to the lithic tools and mammal remains recovered in the excavation as these played a particularly significant role at the site. The results suggest that the cave was occupied on a relatively stable basis although the situation changed in the course of the sequence. Level 1 reflects an occupation linked to the acquisition of meat and animal skins, worked mainly in a fresh state. The use of the site represented by Level 2 may have been more stable and complex, as this level displays greater functional diversity. Tasks involving hard animal material have been documented, as well as dry hide or leather processing. In addition, lithic reduction seems to have been more intense in Level 2. [ABSTRACT FROM AUTHOR]

Few studies have combined the analysis of use-wear traces, traceology, and the proteomic taxonomic identification method Zooarchaeology by Mass Spectrometry (ZooMS). Traceology provides information on the usage, in this case, of bone artefacts, while ZooMS allows for taxonomic identifications where diagnostic features are otherwise gone. The approaches therefore offer complementary information on bone artefacts, allowing for insights into species selection strategies in bone tool manufacture and their subsequent use. Here we present a case study of 20 bone artefacts, mainly bone points, from the Early Neolithic cave site of Coro Trasito located on the southern slope of the Central Pyrenees. Hitherto, studies on Early Neolithic bone artefacts from the Iberian Peninsula have suggested based on morphological assessments that Ovis aries/Capra hircus constituted the majority of the bone material selected for bone tool production. However, the taxonomic identification in this study suggests that, at this site, Cervidae was selected equally to that of O. aries/C. hircus. Furthermore, bone artefacts made from Cervidae specimens seem to be utilised in a wider range of artefact types compared to O. aries/C. hircus. Coro Trasito's bone artefact species composition is probably site-specific to some degree, however, morphological assessments of bone artefacts might not be representative and could be biased towards certain species. Therefore, research on bone artefacts' usage could possibly gain new insights by implementing ZooMS in combination with traceology., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hansen et al.
