I saw part of this clip at the Extreme Mammals exhibit today here at the Denver Museum of Nature and Science, and I'm so glad I was able to find it and watch all of it at home. Mammalian evolution in isolated South America is such an interesting topic!
Giant sloths did not went extint due to the American exchange. Many of South American giant mammals were still slive until 10,000 years ago and then they became extint just like most of the Mega Fauna In other continents .
Adding to this, notoungulates and litopterns didn't go extinct because of the Great American Biotic Interchange either, as this video seems to imply. They also persisted until the late Pleistocene, towards the very end of it.
this is amazing! I am planning to be an animal conservationist and zoologist so this is rather amazing for me to see. I would love to see some of these amazing creatures walking around as if they were still not extinct!
4 years later hows it going?! I want to do that aswell, im gonna try to preserve nature in North America make sanctuaries, help species and animal activism. Im allready vegan!
I think this is an editor problem- they spliced together the isthmus of Panama extinctions 3.5 million years ago with the megafaunal exteintions (Giant Sloth, etc) ~10,000 years ago as the super predator that kills everything in its path, humans arrived in the new world
South america defintly my favorite continent for prehistoric animals. Carnotaurous, Gigantasaur, Argentinasauros, the aninals in this video. Its just my favorite. Next woukd be Australia, than North America, and than Antarctica, and than europe, and than Africa, and than Asia.
The northern arrivals that replaced them are unique and are found nowhere else. That’s because the rise of the Andes have kept South America an island continent.
