[meteorite-list] Example of Lipping and direction stumper. TAKE2

[Jeff Kuyken]

Thanks for that link Martin. I haven't seen that article for a while but 
it's always an interesting read. I have a few unusual Taza pieces but the 
one that really blew me away with it's "dual orientation" was this little 
gem:

http://www.meteorites.com.au/features/taza2.html

I think it shows quite a few similarities with some of the pieces you have 
highlighted. I've always found this particular feature really interesting in 
meteorites.

Cheers,

Jeff
