The question: What are the regional Pokemon? does not address South America (hereby referred as SA), basically because at the time of the posting the game had not launched in South America (SA).
The question linked above was posted before South America launch, and does not address if the north america Pokémon can be caught in South America too. Therefore, not a duplicate.
Tauros is the Pokémon for North America? Is it the same for SA?
If not, is there any hard evidence of some of the "regional" Pokémon being caught in SA?
