At https://archaeologynewsnetwork.blogspot.com/2020/06/extinct-camelids-rev… …. extreme camelids (the camel family), the ancestors of modern llamas and camels, formed in North America, it is thought, based on the amount of bones discovered there. Their presence reveals the past environment, 18 million years ago. It was savannah grassland with clusters of trees. Nowadays, such envrionments are restricted to the tropics – Kenya for example, or the Sudan. This was a blet that existed from Atlantic Africa across the continent to what is now the State of Sudan (the southern half of Sudan and the northern region of Kenya). This particular Sudan environment goes back to the Miocene and it existed in mid latitudes of North America. A large diversity of camels existed thee and they may actually have evolved there as their are fossils of them going back 40 million years ago.
At www.heritagedaily.com/2020/06/on-the-hunt-for-megafauna-in-north-america/ … researchers from Curtin University claim prehistoric climate change does not explain the extinction of megafauna in North America at the end of the Ice Age.
