δ13C AND δ15N HUEMUL (SOUTH ANDEAN DEER) VARIATIONS DURING THE HOLOCENE IN CERRO CASA DE PIEDRA, SANTA CRUZ, ARGENTINA: IMPLICATIONS FOR THE STUDY OF PAST DISTRIBUTION OF HUEMUL. The aim of this paper is to study the evolution of δ13C y δ15N huemul values throughout the Holocene at the archaeological site of Cerro Casa de Piedra (CCP), Santa Cruz province. The paper also seeks to determine the temporal depth of the current isotopic differences between huemul and guanaco in this area, associated with the use of the forest and steppe respectively. Thus, the ancient distribution of the huemul is discussed and a hypothesis presented of the retraction of the species to the forest. Twenty fragments of bone of huemul and 18 of guanaco were analyzed, grouped into the Early (10,000-8000 BP), Middle (8000-4000 BP) and Late (4000 BP to current) Holocene. The δ13C y δ15N huemul values did not record variations during the Holocene and did not differ from modern specimens of the species. Absence of variation in the isotopic values allows the huemul to be associated with either the forest or the ecotonal zones in this region of southern Patagonia during the entire Holocene, which does not support the hypothesis that steppe environments were used by this cervid in the past.
