As requested, and since there seem to be more perverted bone maniacs like me on my F-list, here are some more skulls from my collection. Note that the photos are not in scale to each other. On pig and fox, the jaws are fixed to the shulls with a rubber band.
First my newest aquisition: a male minipig, aged 4 years old. This was an opportunity I couldn't pass by, especially since it takes so much less room than a normal sized pig skull would.
The length of fang teeth is quite impressive, more so from above than from side view. Interesting detail: Because of the angle of the fangs, the jaw can only be moved in a slightly forward motion, not in a vertical motion.
I am fascinated by the differences between the short, dished skull of the modern domestic pig in contrast to the long skull of a wild boar.
A fox, a seagull and a mouse. The blurb under the fox is a piece of rubber eraser, put under the skull to stabilize it for scanning. The fox was probably not older than a year.
Edit: For comparison with the minipig, a skull of a wild boar is here:
