Paleodiets of hunter-gatherers from the beagle channel during the late holocene.

The diets of coastal hunter-gatherers in Patagonia are usually characterized as terrestrial, marine or mixed. This classification may not be enough to describe the flexibility of their procurement strategies. Particularly in the Beagle Channel (Tierra del Fuego province, Argentina) there are diverse...
