I know who that skull belongs to! ....... no-body
Seriously though, finding a heap of bones must be strange, one of the many shipwreck victims along that coast no doubt, poor soul.
Regarding the police not keeping you informed reminds me of a bloke i met last year, digging bait on Alnmouth beach. It was either him or his son (I forget which) found a sword in that little burn that crosses the road.
Dutifully, he takes it to Alnwick Castle museum to see what they make of it.
After a spell he's heard nowt so makes enquiries and it seems the sword has been "mislaid" very sorry.
Probably had a good bit value as well as historical interest, but now we'll never know
