This paper proposes a first approach to the knowledge of the domestic exploitation of animal resources by the Menorcan inhabitants of the Bronze Age, which is made through the study of the faunal assemblage recovered in the dwelling naveta of Cala Blanca. This site, located on the west coast of Menorca, was excavated between 1986 and 1993, and offered a chronology of the mid-second millennium cal BC. Nearly all the species identified are the traditional domestic mammals. Among these, despite the numerical dominance of the binomial goat/sheep, we must stress the importance of cattle. Comparison with contemporary contexts of the island of Mallorca, especially the one from Canyamel, reveals some marked similarities. Finally, the bone tool assemblage from this site has to be noted.
