abyssunder Posted February 14, 2018 Share Posted February 14, 2018 If there are no Schreger lines visible in the transverse section, then is not a proboscidean tusk fragment, but the lines are only in the tusk dentin, not in the cementum (constituent of the outer layer of the tusk), so they are not helpful in this case.

Yeah, I have a few dentin chunks with the lines in them and given the appearance of this one I imagine it is the actual tusk surface. Link to comment Share on other sites More sharing options...
