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 Panthera atrox being more jaguar-like is the trait of the convergent evolution.
Overall, I think it shouldn't be a big deal to distinguish the fossils between the Pleistocene tiger and the Pleistocene lion.
When it is a tiger, it would be surely tiger-like and lion-like for the lion.
I got the impression maybe the Fossilis-Atrox lineage is actually a distantly related subspecies, while the Spelaea lineage is a sister species, could this be possible?
