RECONSTRUCTION AND DYNAMICS OF FOOD STRUCTURE OF THE ODINO PEOPLE IN THE BARABA FOREST-STEPPE AREA DURING THE 3RD MILLENNIUM BC: ACCORDING TO ARCHAEOLOGICAL AND ISOTOPIC DATA
The paper aims at reconstructing the paleodiet of the Early Bronze Age population in the Baraba forest-steppe area of Western Siberia (the Odino culture). The study is based on materials of three large necropoleis of Sopka 2/4A, Tartas 1 and Preobrazhenka 6. Two chronological groups of the Odino culture burials have been defined by radiocarbon dating which gives us an opportunity to research the structure and changes in the paleodiet during the 3<sup>rd</sup> millennium BC. Reconstructions of the paleodiet are based on paleozoological determinations (including bone artifacts) and analyses of carbon (δ<sup>13</sup>С) and nitrogen (δ<sup>15</sup>N) isotopes in human and faunal bones (including some modern faunal samples). Results of isotopic measurements indicate that fish had formed a basic food component in the subsistence of the Odino population throughout the 3<sup>rd</sup> millennium BC. High values of δ<sup>15</sup>N in mushrooms ( Boletaceae ) do not exclude their important role along with fish in the human diet. A secondary food source for the Odino people was meat of herbivores and possibly also omnivores. The main game animal for the Odino population was an elk. Higher δ<sup>13</sup>С values in human bones in the last third of the 3<sup>rd</sup> millennium BC indicate changes in food sources. Preliminary, we associate this signal with an increased consumption of animal products of more southern origins (steppe?) by Odino people, which might be a result of the emergence of domesticated animals in economy.
