The American Lion wasn't "One of the" largest felid to have ever lived, it was the largest felid that ever lived, period. Sabre Toothed Cats and Sabre Toothed Tigers technically weren't true felines but the dependency of Smilodon and its contemporaries comes down to cats being their closest living relatives overall amongst species. Although Smilodon Populator was somewhat larger than the American Lion and Smilodon Fatalis was about the same size, they can not be included or considered the largest "Feline cats" because they come from a different line of evolution. Just like nimravids weren't true Sabre-toothed cats they are classified as "false" sabre toothed cats because they're no real decadency of Sabre-toothed cats that survive to this day. I herd that they didn't even behave much like cats and their personality was more contempt to a Black Bear rather than a Lion or Tiger. The same thing could be said with Indricotherium, it has no direct decadency to this day but we can place it in the closest related group of which is the rhinos, but it comes from a completely different line of evolution known as perissodactyls. So Panthera Leo Atrox is the heaviest feline ever and Scimitar-Toothed cats, nimravids, and sabre toothed cats and tigers are a different ancestry...
I don't mean to be a pest I just want to give you knowledge that I know of, don't take it personal..
The American lion was an impressive feline, his exact taxonomy is heavily debated on weather he should be classified as Panthera leo atrox or his own species Panthera atrox,at the moment it is belived that he and the cave lion were sister species.Also the lions living in Beringia were cave lions,wheres the American lion lived south of the glacier from Alberta onwards.
very nice my friend but i think this is an almost medium american lion or have a size that it is between medium and minimum or small size of an american lion. some of lions size is larger or very larger that some of lion,s head length and body length is around or about 8-9 feet(2.4-2.7 meters)or even more and a weight more than even more than 900 ibs or more than 405 killograms. thanks for you,re great art my friend. graciasssss!!!!!
