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.

Convergent evolution is a difficult aspect. In many ways, mostly regarding skull width, jaguars, P. spelaea, and tigers are similar while P. atrox and P. fossilis are more lion-like. Had the Javan tiger not existed one could even say the Ngandong skull was lion-like, but we know that modern Javan skulls are quite lion-like in their proportional width.
A lot of the skulls' features may have to do simply with the parent lineage, whose gene pool subsequently limits any adaptive change later on.
I could post some skull pictures and we could analyze the differences and similarities.
