Megapredators of Ice Age North America

North America once had one of the most diverse arrays of large predators on the planet, including both living species and species that have gone extinct. For each picture label the animal shown.
Ice Age Alaska was separated from the rest of the continent by an ice sheet, and shared wildlife with Eurasia. Animals marked with an asterisk were only found in Alaska until the ice sheets melted

I could find very little on Miracinonyx inexpectatus, the second species of American Cheetah. I am far from certain that it existed in the end-Pleistocene like the others did. Included it anyways as I was able to find a picture and might as well.

This list is possibly missing at least one species of Arctotherium, a genus of South American short faced bears. As I could not find any good public pictures of those species, and their range in North America was pretty unclear, I decided not to include them. I did include tigers, even though their range in North America was limited to Alaska, and if they actually even lived there is really unclear. The difference, of course is that I can easily find pictures of tigers, while Wikimedia Commons pictures of Arctotherium are scarce.

Goes without saying from the presense of crocodile and alligator species that Central America was pretty warm, even during the Ice Ages, and could support crocodillians.

I have updated the quiz with a new Homotherium reconstruction by Triloboii. With the homotherium cub mummy described a couple months back, the newer drawing is likely a bit more accurate as the teeth are covered, and its fur is darker. Was tempted to add a picture of the cub instead, but it would be a bit out of place here given that the rest of the pictures are adults.

I like this quiz idea a lot! I definitely learned something from it and it was interesting seeing the pictures of the animals.

Interesting quiz.

Though I feel that sabretooth should be accepted.
