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.

Is this a little bit too long for the CBL?

Did P. Christiansen (2008) really state this is the CBL, not GSL?


I noticed that too. Something is odd about the way the mandibles were measured for the CBL to relate by 1.5x. The paper is attached. He only refers to CBL everywhere.

Maybe the measurement came from the bottom of the lower jaw instead of the entire mandible?

BTW, the Padang specimen might have proportionally smaller canine teeth the modern tigers, hence the difference of proportion needs to be coped.


That method of measurement would make sense and could explain why in this study the lion has a much longer mandible proportionately than the tiger. If the mandible was measured from the angular process to the symphysis and the coronoid process was not measured, the tiger would appear to have a proportionately shorter mandible as tigers generally have a coronoid process that extends beyond the inferior processes.

The smaller the canine teeth proportionately, the longer the skull. That would make the skull fall off the scale in terms of size. The opposite is also a possibility.


I do recall that you gave the conclusion that the Padang mandible is overall more robust than the mandible of the specimen 2900-3 of Panthera atrox.

However, the lion-like felines always got longer coronoid process in count. Therefore, at the similar length, the tiger-like felines would usually get more robust mandible.


I have actually noticed that the tiger has the least robust mandible in terms of height. Here's a comparison with the mandibles scaled to about the same length:

Anteriorly and posteriorly, the tiger has the shortest mandible. Posteriorly, the lion has the tallest mandible. The American lion consistently has a tall mandible for its length throughout.


But wasn't the Padang mandible proportionally robust compared to that of Panthera atrox?

BTW, maybe the robusticity can be varied over time.
Well I don't think Padang tiger could as robust like Panthera atrox,  even the total length of skull may couldn't up to 480MM, it just the level of modern Panthera species maximum length. 

Could you tell me how body-size you have calculated @tigerluver ?  in my opinion, the prehistoric tiger's body-size may be greatly exaggerated
