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.
Perhaps I shouldn't say anything, I am not specialist, but I really think that an apex predator's size must be correlated with the preys that are available. And as concerns the Atlas lion, what were they ? Wild goats, boars, perhaps some small antelopes and that's all ! Why were these lions bigger than the extant lions which hunt regurlarly some big preys like zebras, buffalos, giraffes and so on ?
Thus IMO, the Atlas lions having never regularly preyed big (wild) animals for an eternity haven't any reason to be particularly big. Generous-maned lion, yes, big-sized lion, no.
