Wasn't that the possible finds made by Graham Mullan and Linda Wilson at Aveline's Hole in 2003 as eyt unconfirmed . There were others at Long Hole but they were even more unlikely .
Probably so but its too far back, they were really vertical scratch marks, perhaps something like in the Banks Tomb, but only about half a dozen lines...http://www.themodernantiquarian.com/post/98351/banks.html
