Question

Why did the Panthera leo atrox go extinct?

Answer 1

The relationships of Panthera atrox, often called the American lion, to other big cats have long been contentious. A few paleontologists even went so far as to assign the extinct American cat to Panthera leo rather than to a separate species.

Answer 2

HEY GOOD MORNING☺☺☺☺
it was later assigned as a subspecies of p.leo ( p. leo atrox ) rather than as a separate species...... it was proposed that it arose from pantherines that migrated to north america during the mid - pleistocence and gave rise to american lions and jaguars ( panthera onca )
