There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Panthera atrox could possibly be evolved from Panthera youngi, which could be the Asian offshoot of Panthera fossilis.
Unlike Panthera fossilis from Europe, Panthera youngi was always deemed as its smaller relatives.
Maybe during the arrival of Panthera atrox, its size was rather moderate like Panthera youngi, and Panthera atrox from North America has seized the position as an apex predator, while Panthera atrox didn't seize the domination position, thus it didn't grow larger at all.
