This work presents the world literature review, reveals the features of isotopic analysis in the context of vertebrate animal ecology and the methodological hardships at work with fossil material. The particular cases also show the successful usage of isotopic analysis for specimen identiﬁ cation of archeozoological remains, especially bones of brown and polar bears, large marine mammals and a few specimens of anseriformes.</p></abstract><trans-abstract xml:lang="ru"><p>В статье обсуждаются возможности использования изотопного состава углерода (соотношение 13С/12С) и азота (соотношение15N/14N) для таксономической диагностики костных остатков животных из археологических памятников и других древних отложений. Представлен обзор мировой литературы, раскрываются особенности изотопного анализа с точки зрения изучения экологии позвоночных животных и методологические трудности работы с ископаемым материалом. Приводятся также конкретные примеры успешного применения изотопного анализа для видовой идентификации археозоологических остатков, в частности, костей бурого и белого медведей, крупных морских млекопитающих и нескольких видов гусеобразных.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стабильные изотопы</kwd><kwd>кости животных</kwd><kwd>таксономическая диагностика</kwd><kwd>археозоология</kwd><kwd>Ursus</kwd><kwd>Hydrodamalis gigas</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stable isotopes</kwd><kwd>animal bones</kwd><kwd>taxonomic diagnostics</kwd><kwd>archeozoology</kwd><kwd>Ursus</kwd><kwd>Hydrodamalis gigas</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Антипина Е.Е.
