Megapredators of Ice Age North America

Removed M. inexpectus as I found some info that suggests that it was just an early pleistocene version of the American Cheetah, and did not survive to the end pleistocene. On a further look, I have been able to identify the Arctotherium species native to North America as Arctotherium Wingei, a small short faced bear about the size of an American Black Bear, and native to Central America. I have been unable to find any public use reconstructions of it, more or less every drawing of Arctotherium species out there is for A. Augustidens, which was about twice as big as A. Wingei, and native to South America. If I ever find any free license paleoart of A. Wingei, I will add it here, as it is to my knowledge the only large North American predator missing from this list.

I arbitrarily decided that "megapredator", is a predator over 100 pounds. Considered adding coyotes and the rare Pleistocene dhole, but I figured that adding them would necessitate adding lots of random midsized predators
