The Cave Lion (Panthera spelaea and Panthera fossilis)

[tigerluver]

@Ghari Sher , great post! P. spelaea, at the diaphysis, seems to have the thickest bones. At the epiphysis, off the top of my head all the lion-like cats are more similar in robusticity but the extinct species were again a bit thicker. As a recommendation, when calculating robusticity try using "ratio/index = bone width/bone length". This is more conventional as the greater the ratio, the greater the robusticity. Another issue to note is that the diaphyseal diameter differs between researchers. Some assume midshaft diameter equals the least diameter of the diaphysis and others actually find the point where the diameter is truly the least, confounding comparisons a bit. I am short on time so I apologize for not being able to write a more in depth response at the moment but I wanted to make sure to acknowledge the great work. Reply
