That really would be great.
I've got a persian cat skull imgur.com/a/4SJVa
(I think the shape isn't too extreme for a persian cat, I've seen way worse skulls)
A Russian Blue: imgur.com/a/7od34
this one is in a bad condition. It was my mother's cat, it died in a car crash, the skull fell into 4 big pieces and a lot of splinters. It was burried near a tree, so the roots damaged the skull even more.
Because of this, it is hard to tell the difference of the breed, but I think the jaw looks completely different from a European Shorthair: imgur.com/a/YqUmn
The coronoid process (?) of the Russian Blue (below) is longer and different in shape the the coronoid process of the European Shorthair (up)
I think most of my cat skulls are European Shorthairs, but I will never know for sure I think, I can't find enough references. The bigger cat skull, I showed you once 10,5 centimers long, is probably some other breed, but that will stay a mystery as well.
I would really appreciate a cat breed/species reference material
You can find a lot of information about dog skulls, information on cat skulls is harder to find.
