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.
The only two Panthera species that made their way to the heartland of America were Panthera atrox and Panthera onca, but Panthera spealea and Panthera tigris (based on few fossil remains) stranded in Alaska for some odd reason.
I assume that the eastern part of North America is suitable for tiger's habitation, while the western part for lion.
As for South America, the northern part is dense jungle, thus suitable for tiger. And the souther part is open plain, thus for lion.
