Parachoerus carlesi (Mammalia, Tayassuidae) in the Late Pleistocene (northern Argentina, South America): paleoecological and palaeobiogeographic considerations

The Tayassuidae is one of the first families of North American immigrant mammals that arrived into South America during the ‘Great American Biotic Interchange’. They have been found associated with Late Cenozoic deposits mainly in Argentina and Brazil, but also in Uruguay, Bolivia, Colombia, Peru an...
