Prehistoric Animals That We Are Glad Went Extinct

American lion

#12 American lion

The American lion is a species of lions that is estimated to be about 20% bigger than normal lions. As if lions weren’t scary enough already!

They were bigger and certainly stronger than the lions today. They preyed on mammoths and other big animals in their time.

You wouldn’t want to encounter one of these bad boys on your morning hike in the woods. Much to our relief, the American lions disappeared 13,000 years ago!
