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.
Regarding P. spelaea (not P. fossilis) size, the NW Germany specimens look quite large. The 475 mm skull of Ural is huge as well, though I'm not aware of any exceptional long bones from the area. The British cave lions seems smaller, literally lion-sized. The far east Russian lions seem bigger than the British form, but smaller than the NW Germany and likely the Ural form. This may be why P. spelaea didn't get into the Americas after P. fossilis' colonization, they were smaller than those specimens, but still shared the same niche, so they were beat competitively.
