Most meteorite petrographers have a lot of experience looking at meteorite
whole rocks, not just thin sections. Over the years, I can usually tell a
meteorite from a wrong, but when I am not sure, I make a thin section before
making an announcement. What I am not so good at is guessing what kind of a
meteorite it is before I see a thin section. Jason Utas, for example, is
much better at that than I am.

Michael,
A lot of times scientists used to working in labs with thin slices can't
tell an ordinary chondrite from a hole in the ground. They often
specialize in a narrow academic field and have no experience handling all
different types of meteorites. It's hard to beat years of hands on
experience when it comes to field grading meteorites. Plus, these stones
have highly unusual crust. I didn't think they were meteorites because of
the weird crust, but it's hard to tell just from looking at an out of
focus photograph.

Am I to understand that one of NASA's best has problems identifying a
meteorite? Is anyone else concerned by that?

Of course it is. Sadly the damage is done. I am in Germany and all I am
