Thanks John. I get it now, it's the word fossilized that's causing the confusion. I'll concede that it's not completely accurate, but the term gives the reader a fair idea of what sort of product he or she is reading about or about to buy. Anybody check out the link to the graveyard of the mastodons or hear of it before? If such a place still exists there must be tons of fossil...er..very old ivory still there.
