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.

Sabol (2011a) also suggests that P. fossilis populations were separated by the mountain-living P. spelaea. In other words, the two forms coexisted at a period in time and were incompatible enough to not interbreed.
If they don't interbreed, like the case of the Alaskan Panthera spelaea and the North-Central American Panthera atrox, this is another evidence that these were already different species and not only "subspecies". Maybe, although similar in skull morphology, they were like the leopard and the lion, very close and similar, but different in ecology, some biological items and even coat pattern.
