Table 2 Edible resources in the carcasses abandoned by the large carnivores considered in the experiments. The body mass of the preferred prey is based on isotopic analyses of fossils from Venta Micena80. The wastage factor accounts for the non-edible percentage of a carcass and is dependent on the body mass82.
