However, the dietary habits of these ancient humans remain debated, with conflicting evidence suggesting that they may have been primarily carnivorous, omnivorous, or even herbivorous. Traditional isotope analyses have provided some insights into Neandertal diets, but their limitations (preservation and baseline effect) have sparked the need for new approaches. These limitations are well known on the Iberian Peninsula, and while recent results of carbon, oxygen, radiogenic strontium, and zinc isotopes and trace element ratios allow the reconstruction of the Gabasa (Spain) Neandertal diet, some questions still remain unanswered. Our study explores the potential of using calcium and stable strontium isotopes (δ44Ca and δ88Sr, respectively) to supplement previous analyses performed on the Gabasa Neandertal. Based on the low δ44Ca and δ88Sr values observed for the Neandertal specimen, our results suggest a hypercarnivorous diet that included low but non-negligible quantities of bone, although it is not possible to rule out the possible impact of milk consumption. Overall, our work argues that Ca, Sr, and Zn stable isotopes can supplement conventional isotope studies and offer a more comprehensive picture of human diets, including that of Neandertals. info:eu-repo/grantAgreement/EC/H2020/803676/EU/Understanding the onset and impact of Aquatic Resource Consumption in Human Evolution using novel Isotopic tracerS/ARCHEIS This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 803676-ARCHEIS info:eu-repo/semantics/embargoedAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Guiserix, Danaé Jaouen, Klervia Montes, Lourdes Universidad de Zaragoza (orcid)0000-0003-0628-2582 Utrilla, Pilar Universidad de Zaragoza (orcid)0000-0002-9181-9833 Villalba-Mouco, Vanessa (orcid)0000-0002-9357-5238 Maureille, Bruno Balter, Vincent 3000 695 Universidad de Zaragoza Dpto.
