EDIT :Changed the height of the African lion, he was just WAY too small in the first upload. I think I'm a bit happier with him in this edited version.
Just a pic showcasing the possible size differences of an American Lion (now extinct) and a modern day African Lion.
There's been alot of speculation on the over all appearance of the American lion. Did it have a mane or not? What was it's pelt like? Was it even considered (by today's species charts) a lion at all?
As for me, I( hope it had a full mane like today's lions, why? because I think it would be awesome to have basically a super sized lion of today. 8)
Well we may never know. And as far as a specific height goes? I may be a bit off on this image. The reffs I looked up all had different heights, So I just "guesstimated".
