About how long ago did North America host camels, American cheetahs, lions, giant ground sloths, tapirs, muskox, giant beavers, elephants, and giant tortoises?
- A 13,000 years ago
- B 65,000 years ago
- C 1.6 million years ago
That's Correct!
It's Wrong!
The North American mega-fauna listed, which also included the sabre-tooth cats and mammoths and mastodons went extinct 13,000 years ago during the end of the Pleistocene, presumably caused in part by over predation by human migrants from Asia, who we call "native Americans" today.
