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.
