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.
P. spelaea was smaller, and if it coexisted to some extent with P. fossilis (which it likely did), they prey bases would be different due to niche competition, likely explaining the canine discrepancy. Although, comparing two of Marciszak et al. (2013) skulls, P. spelaea had thicker/wider canines. I've a bad feeling P. spelaea and P. tigris fossils are being confused with each other, the skull features are very similar regardless of the common belief that P. spelaea is a true lion. P. fossilis/atrox are much more lion-like.
