Zooarchaeological and stable isotopic assessments on pinniped-human relations in the Beagle Channel (Tierra del Fuego, southern South America)

Recent zooarchaeological investigations in the Beagle Channel region have shown long-term variations characterised by a high inter-taxonomic dominance of pinnipeds during the first moments of the archaeological sequence (ca 6400 bp) at the Túnel Locality and a decrease in the relative importance of...
