Skull in West Linton Graveyard

I had to almost lie on the ground to take this skull which was lurking at the side of one of the very old table graves in West Linton Graveyard. All writing on the table stone itself has completed gone and it isn't mentioned either in Peeblesshire Monumental Inscriptions so I have no further light to shine on it.
Apart from the fact that the skull seems to be having problems with its mouth!
I seem to be featuring more and more graveyard pictures as well as spending time in graveyards. No excuses, I just love them!
