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.
In regards to the skull, a tiger generally has a wider skull per inch but when both skulls are at their maximum, a lion will usually hit the 15" while a tiger will hit the 14" mark and both are fairly close in width, thus the lion having the larger skull in absolutes. Usually both weigh close to the same but once again the lion generally has the longer skull.
If the tiger skull library was larger in regards to 16"er's my opionion may change but the fact remains that those skulls are very hard to come by.
Interesting notes on limb robusticity, but I'd have to research on what fiber differences they would have compared to one another. I'd assume that two animals built for the same thing and being of the same genus would share mostly the same fiber distribution.
In regards to the sq inch remark, you can generally see that both have similar front limb lengths but do not share similar girths, thus my mass per sq inch remark.
