This article presents the results of the zooarchaeological and taphonomic analysis of the Cañadón Las Coloradas 1 (CLC1) site, located in Alicurá, in the middle Limay river basin, in a steppic environment of the Río Negro Province (40o35’55.6’’S, 70o45’48.9’’W). The site comprises remnants of human occupations of the Late Holocene, from before 1525 ± 80 14C BP, until recent times. The conservation of bone remains and the impact of natural agents and processes were moderate. The hunter- gatherers that inhabited CLC1 exploited Lama guanicoe (guanaco) for meat and skins, complementing their subsistence by the exploitation of smaller-size species, such as Rhea pennata (lesser rhea) and Chaetophractus villosus (large hairy armadillo). Taphonomic studies point out that the remains of the exotic mammals Ovis aries (sheep) and Lepus europaeus (European hare) do not show evidence of human consumption. The latter species was useful to generate a relative chronology.
