[meteorite-list] Oriented Meteorites?

[Brandon D.]

Hello Everyone,

I have a question I'm sure can be answered here to my satisfaction.

What defines an "Oriented meteorite"? I've noticed a trend starting where people have begun calling any meteorite with a rounded edge oriented or "slightly oriented".

What truly defines an oriented meteorite? I have dozens of shields with radial flowlines and bullet shaped stones and irons, so I see orientation, but what's the true criteria? 

Thank you ahead for any replies.

Best,
Brandon D.
