its already been scrubbed and such
and I find them fairly often at my cottage, one time we found a 9ft long rib bone, theres also two shipwrecks nearby and last year the skin of a whale washed up on our sea wall and we thought it was a polar bear because it was this huge thing with white hair, turned out to be a piece from a dead humpback and the white "fur" was decayed blubber fibers, cool huh!
I live on Prince Edward Island, Canada btw
