This was a grey squirrel skull I found in the woods.

Coin is a Beatrix Potter Peter rabbit 50p, it is 27.30mm approx and used as size reference.

Sadly, it was in a trap. Someone had wedged the trap under a root and left it there. Would have been more humane to either let it go or destroy it, then let it starve in a cage terrified. Too bad I found it long dead, or i could have released it.

Originally, thought it was either a rat skull or squirrel skull. r/vultureculture on reddit confirmed squirrel for me.

My vulture culture collection is now this Grey squirrel skull, a European rabbit leg bone, Muntjac deer hip bone, Domestic canary bones and skull, European rabbit skull, another European rabbit skull but with crystals on it, a Domestic cat skull, and a Guinea pig skull. I have a medium size bird breastbone? I need to clean mud from more, and a diaphonised fetal rabbit head wet specimen aswell.
