“…Currently, this species is extremely abundant in shallow, coastal habitats of Tierra del Fuego and other silverside species exist along the coastline of Argentina, as north as the Río de la Plata (Dyer, ). Furthermore, silverside bones have been recovered from shell middens from other areas of Tierra del Fuego near the Magellan Strait such as Marazzi 32 and Punta Santa Ana 3 (Morello et al, ; Torres, ). Consequently, the absence of silverside from Lanashuaia II and other archaeological sites from the Beagle Channel is not because the species was absent from the region during the Late Holocene, but more likely because HFG societies inhabiting the area did not exploit it.…”

Stable carbon and nitrogen isotope ratios in the skeletal elements of both ancient and modern marine species from the Beagle Channel were used to compare the structure of Late Holocene and modern food webs, and predict potential changes as a result of a Sea Surface Temperature (SST) increase in the region. Complementary, ancient and modern shells of limpets and mussels were isotopically analysed to explore changes in the isotopic baseline and compare marine food webs through time after an appropriate correction for baseline shifts. Results confirmed a declining pattern of marine primary productivity during the Late Holocene in the Beagle Channel. In general, the isotopic niches overlapped largely in the ancient food web in comparison to the current marine one, with the exception of that of cormorants (Phalacrocorax sp.). Our data suggest that all the species that have undergone intense human exploitation (Arctocephalus australis, Otaria flavescens and Merluccius sp.) significantly increased their trophic levels. The most important finding of this work was the very high isotopic overlap between snoek (Thyrsites atun) and hake (Merluccius sp.) during the Late Holocene. Increasing SST as a result of global warming could favour the recolonization of the southern South‐Western Atlantic Ocean by snoek from the South‐Eastern Pacific Ocean, with a potential impact on the landings of the economically important Argentine and Austral hake. These findings highlight the relevance of using zooarchaeological remains for providing predictions about marine food webs changes in the near future.

“…La discusión acerca de su origen tiene un efecto en la arqueología de Magallania insular, en tanto la adscripción de este locus como un gran campamento lo vuelve un área nodal (Oría, 2014), como el sur de Bahía San Sebastián (localidad Chorrillos), la costa de Bahía Inútil (localidad Marazzi y Bahía Inútil) y la costa del Estrecho de Magallanes (localidades Cabo San Vicente, Punta Baxa y Punta Catalina) (Horwitz, 1995;Massone, 1997;Morello et al 1999Morello et al , 2012Massone et al 2003;Martin et al 2004;Massone & Torres, 2004;Morello et al 2005;Massone & Morello, 2007;Borrero et al 2006;Torres, 2009;Pallo, 2012;Borrazzo, 2014).…”

“…Chozas pre-preparadas. Es pertinente ante todo mencionar la evidencia arqueológica de casaspozo apud Bird de Punta Silvestre, isla Isabel, con remoción de arena de base (Borrero et al 2019) o de Punta Santa Ana 1, con deschampado inicial, reconocido a partir de estudios micromorfológicos Morello et al 2012). La evidencia etnográfica es muy abundante.…”
