Island subsistence during the Late Bronze and Iron Age in Menorca: insights from stable isotopes and Bayesian mixing models at the Biniadrís Cave (Spain)

• Isotopes reveal a strongly terrestrial diet at Biniadrís from Bronze to Iron Age. • Bayesian models show balanced livestock use, with rising pig consumption over time. • No marine resource use, despite immediate coastal access. • Evidence points to resilient, adaptive dryland agropastoral strategies. The Biniadrís cave, a Late Bronze and Early Iron Age funerary site in Menorca, Spain, offers exceptional preservation for investigating dietary patterns in the Western Mediterranean. Stable isotop
