The South American foxes (Lycalopex), commonly called raposa in Portuguese, or zorro in Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, Lycalopex griseus, is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt.
The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene. The Vorohué Formation of Argentina has provided older fossils, dating to the Uquian to Ensenadan (Late Pliocene).
