[meteorite-list] Meteorite unclassified

[Rhett Bourland]

Honestly, just because a meteorite is found in a known strewn field doesn't
automatically make it part of the same fall.  Twink Monrad found Golden
Rule and Golden Mile in the Gold Basin strewn field.  Calcalong Creek was
originally sold as part of the Camel Donga strew field.  NWA482 was
originally thought to be a eucrite.  The folks who go to Antarctica each
year go back to the same areas to find more because of the way glaciers
move.

When talking about how not getting everything classified is bad for
science, that isn't just about common material being sold as something much
rarer.  The real danger is rare and scientifically important pieces being
sold as something more common.
