What did you end up doing with it? I hope my interest in it doesn't seem too morbid! It's just sort of fascinating that you find animal skulls in forests! I mean like, I've never found one. It's sort of cool and interesting.
Were there any other bones around it? Was it an area where there were deer or sheep?
We found the skull attached to a tree bizarrely - it was all very Blair Witch. After wandering around with it for a while we ended up planting it on a stick in the middle of the forest. There weren't any other bones about, but it's Scotland so there are deer and such
It's actually an app on my iPhone, it imitates classic lenses and films (you can change them and mix and match). Very effective, and surprisingly accurate. That particular lens is a Helga of some sort, it seems to blur more than the others.
