FF7 masters, eh? Amatuers.
I don't think there is an exact location for missed treasure in Bone Village(it might change each game, or just be random). I believe you just search for normal treasure(I think it's "Normal treasure", but I could be wrong; I haven't played in years).
I'll have to see sometime if I have some save points anywhere near to see if I can pin-point an exact location to missed treasures for digging up. But not now. *lazy*
