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.

Since the broader snout should be a trait that belonged to the Mainland tiger group.


It's too hard to say right now. I am going to be taking a lot of measurements on a lot of skulls in hopes that I can detect differences between subspecies with just the anterior half of the mandible. As of now every scenario I have hypothesized is rejected by some extant specimen somewhere. In the end, I'll be doing a morphological cladistic analysis and I really hope a lot of measurements can make up for the lack of the rest of the specimen. 

@GuateGojira , very nice comparisons. The fact that the photo I released has some issues with distortion is probably playing a part in making the reconstruction look a bit off. Add to that, the extant comparison specimens have differing body to vertical ramus ratios.

Interestingly, as @GrizzlyClaws mentioned, P. atrox has the best fit in terms of shape for the mandible. My theory is that allometry is playing a part, as giant need to be compared with other giants to prevent allometry confounding comparisons. In other words, smaller animals have different development than larger animals, in turn making a comparison between a 470 mm skull with a 320 mm skull likely inaccurate. Between P. atrox and the fragment, the contours are very similar. However, in the tiger fragment the canine is quite a bit larger (expected) and the dentition are anteriorly shifted (also expected as tigers have shorter snouts).
