Abstract: The Troitskiy cemetery, a very important site of the Mohe ancient culture, is located in the coastal and middle portions of the Jieya River, in the far??eastern area of Russia. In this study, we examine the Troitskiy human paleodiet using stable isotopic ratios of carbon and nitrogen in bone collagen. Nitrogen isotope ratios of bone collagen show that the Mohe ancient inhabitants from this cemetery ate primarily animal products with only a small amount of plant products. Carbon isotopic ratios of bone collagen show that most of the plant products came from C3 plants.

Key words: Mohe; Troitskiy cemetery; Stable carbon and nitrogen isotopes; Paleodiet
