i dont know really what this is but why else are there tally marks on it.all help welcomed. href="http://s1023.photobucket.com/albums/af358/hilbly/home%20front/?action=view¤t=DSC00141.jpg" target="_blank">
The marks in the last pic view certainly look man made
Other than that I dont know what to make of it other than judging from the size compared to your fingers.. . . if I was going into battle to hammer the enemy, I would choose a pebble with a little more clout
