Those who collect information with the fossils are not disreputable.  (To
be clear, I was using an alternative form of "wrong," which is what Eric
Lurio said).  A disreputable person is one who collects fossils as
commodities and not as scientific resources, and who will not consider the
needs of the scientific community when important material comes to light.

In short, we are to determine who is disreputable by actions.

 Are all private
>individuals who have personal collections of fossils disreputable?

No.  In fact, I know the person who owns the pterosaur you are working on,
and saw his collection over the summer.  Although I disagree with his
political orientations, he is not disreputable - he works hard to keep the
information with the fossils.  Although I disagree with the concept of
publishing on fossils in private hands (I would rather see this person
donate and/or sell the fossil to a museum before you work on it, and you
are limiting the number of possible publication venues by working on it
prior to curation), this is clearly a specimen worthy of description, not
only because of its informative content, but because the important
contextual information was preserved.

Willis, Salisbury, Langston.

  Unfortunately, the specimen was

Not "better off" - that was certainly never my point.  My point is that
such a fossil is no different than if it had not been collected.  So we are
in the same shape as before.

 Perhaps so, but I don't think so.

Too bad under the conditions you describe the important points it whispers
were never transcribed.

 Who are we to ignore its whisperings just because it

 Yes, it would be

Not nice - _necessary_.  And if we cannot say where it comes from, we are
not better off for knowing about it.

In point of fact, I've actually seen fossils that might overturn parts of
my work.  The locality/temporal information was so bad that I could not, in
good conscience, include it.  Remember, parts of my work include
stratigraphic and biogeographic congruence - if I don't have that
information, it does very little (if anything) to move us forward.

I don't either, but we seem to disagree on the solutions.
