This isn't another thread asking "what might happen if horses survived in North America?". It is a similar type of thread, but does not involve the Great Pains or North America.
The megafauna of Patagonia died out before humans arrived in the area, but what if they hadn't?
So I pose two senarios, the first being this. What if the Patagonian Megafauna had survived to the point when humans arrived in the region, going extinct in the rest of the Americas? The migratory peoples who came to Patagonia aren't going to be in the great numbers as those farther north and so the megafauna might be able to adapt to their changing world, just like the Rhea did OTL, and so instead of humans being the reason for their demise they are instead the reason for their propigation outside of Patagonia and their reintroduction into to the rest of South America. Just to let you know, this means that their would be two species of Mastodon living in South America: Stegomastodon and Cuvieronius.
The second senario is "What if the Patagonian horse survived and was dommesticated?"
How would this affect the plains nomads of Patagonia and the rest of South America?
