SOMEONE had found this mammal skull and left it on one of the display boards at Ash Landing National Trust reserve, providing an impromptu quiz. What was it?

Even though the long canines at the front are missing, it’s obvious that this isn’t a rabbit or hare, it’s too large and long anyway, and to me it isn’t as broad and powerful as I’d expect for a badger so I’m going to guess at Red Fox.
And the answer is . . .

I’ve added their labels to my photograph. Alveoli are small cavities or pits, and here in an anatomical sense, that means the bony sockets for the root of a tooth. These three holes supported one tooth, as you can see from the opposite side of the jaw.
Oh, in case it’s not clear, the two lines are intended to indicate the cranium between the two eye sockets.
