DNA from the animals... the shell is essentially inorganic. The
conchiolin of the shell's matrix and periostracum or the operculum...
not sure if there is any DNA in these, as they are secretions, not
cellular structures.

If the right part of the DNA is chosen, this can yield good
information on relatiionships. If the right part is NOT chosen the
results can be spectacularly wrong. Remember, though, that just like
cladistics, experience and hunches, molecular work is merely a
method, not the absolute.
