Magallanes Basin

The Magallanes Basin is a major geological unit reaching as far north as upper Patagonia in Chile. This unit derives from the Jurassic era and includes the Cerro Toro formation. This basin offers opportunities to study numerous ancient fossil lifeforms and other prehistorical natural features due to the deep sedimentary layering.

Prehistoric man
Certain geologic formations within the Magallanes Basin offered early humans rock shelters and caves; one of the most notable of such locations is the Cueva del Milodon, a site where ancient man was known to live, based upon the archaeological recovery from this series of caves.
