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.
It would make sense to me that since some groups of cave lions, having developed the habit of hunting cave bears, probably due to a scarcity of their usual prey, would have also preyed upon the brown bear as well. Brown bears and cave bears are very similar. Fossil evidence of this would be rare if any due to the fact that the remains would not be so well preserved as in a cave. Brown bears rarely den in caves. Perhaps it is simply nature's way that juvenile bears and even adult bears of some species must be ever aware of big cats.
