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.

These seem to be the four canine teeth of a single individual bear. Are they? What are the odds of finding the complete set of fossil canines in the field? Or they were attached to the fossilized skull and extracted from there?

Yep, most likely extracted from the same skull.

A real 3 inches tiger claw without being stretched from the knuckle bone.

Below looks like a lion claw.

Male jaguar of unknown population and African lioness skulls side-by-side at one of Dublin's museums.

It is interesting to see the striking differences between the length ratios in both specimens. In terms of skull height, they seem pretty even, while the lioness has a more elongated rostrum with broader nasal cavities and a more pronounced internasal suture. The jaguar on the other hand has significantly wider zygomatic arches with a shorter rostrum and smaller nasal cavity. It also has longer and thicker canines that are particularly pronounced at the root. It's hard to tell from these angles but it also appears as though the orbits in the lioness are slightly larger while the jaguar has a more pronounced sagittal crest.

Looking at these two skulls side-by-side we can tell how the anatomy of the jaguar is wired in such a manner that it can support a stronger bite force proportionally that the lion, with the pressure being particularly supported around the molars. The wide zygomas and tall sagittal crest are supported by huge masseter muscles at the back of the skull.

It would be interesting to see if these differences would diminish on a proportional basis if a male lion skull was used.
