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.
On the big cats, I see that lions possess more robust humeri than tigers at most cross-sectional areas, but in the tiger, both the ulna and radius corticalbone thicknesses are more increased within the tiger than the lion by a significant amount, assuming equal weights, of course. Same as in bears, with A. angustidens having more robust humeri than either A. simus or some modern bears. Am I reading your conclusion right?
