title: First Experience of Using Isotope Analysis to Establish the Diet of People and Domestic Animals in Ancient Coastal Settlements of the Kerch Peninsula
abstract: The results of studying the bone tissue samples of humans and domestic pigs from some ancient monuments of the Kerch Peninsula in Crimea are given. The diets of humans and animals are determined by the content of carbon and nitrogen isotopes in their bones at the time of death.
