Not sure how to rate this as it's practically dead animals, but heck it's just schematic skulls. xD Picked moderate.

Anyway, for a school project I was asked to draw Guinea Pig skulls with different dentals for a game. You can see the first four here: https://www.weasyl.com/submission/559641/guinea-pig-teeth-or-not (Guinea Pig, carnivore, rabbit, bird).

This fifth and last one is based on the dentals of a swine, so actually it's a "double pig". x) Yes I'm hilarious.

Feel free to use these by the way if you somehow find a use for them, but please give credit. Also they're in no way a good reference and you're better off using photos of skulls or schematic drawings out of proper books or something. I used references for these!
