Thanks to careful coordination between scientists, hunters, and collector/dealers, the various individual separate finds were gathered together under one lead and this was collectively classified to achieve a single non-anonymous entry in the Meteoritical Bulletin. Previously, a find like this would have been split up a dozen ways independently with no communication or coordination between the parities who acquired material from the field. Each party would have classified their own material, which would have resulted in several redundant and anonymous "NWA xxxx" entries in the Met Bull. Instead, we now have a single concise accounting of this new find. Well done to everyone involved. This is how it should be done. :) Best regards and happy huntings, MikeG -- ------------------------------------------------------------- Web - http://www.galactic-stone.com Facebook - http://www.facebook.com/galacticstone Twitter - http://twitter.com/GalacticStone Pinterest - http://pinterest.com/galacticstone ------------------------------------------------------------- On 8/21/13, Galactic Stone & Ironworks <meteoritemike at gmail.com> wrote: > Agreed about the name.
