Come on, this attractive IRON (as sculpted irons go) does have some interesting morphology - this * is * quite a curiousity ! It is hard to tell from the photos, but it seems to me that the specimen in fact was probably a ring shape with some degree of orientation. The center of mass would appear near the thickest portion of the meteorite, smooth, and with trailing (though not particularly extended) regmaglypts. What I find especially interesting out Steve's new meteorite is contemplating the explanation for its shape. It shares too many characteristics with the regmaglypted (non-shrapnel) Sikhote-Alin specimens to be dismissed as simply shrapnel - clearly I think it is not. One can contemplate, whether it looks like it was a relatively rare, ring shaped mass that separated in the early fragmentations, and then maintained some sense re: fatter side, where the inside trailing ring violently waffled back and forth and was burned or torn off at just the right time (i.e. still with high enough velocity when hitting the dense part of the atmosphere needed to give the duality), which left just the rudders. Certainly not the best example of a bulbous single axis orientation in the line of flight, more like a boomerang and a backbone by the time it landed. Boomerang: "A boomerang is an aerodynamically shaped object designed to fly efficiently through the air when thrown by hand some designs which return to the thrower and others that don't." [and if it ends up on eBay :-) ] As to what Steve paid for this (which included a stamp which I've seen for $20), whoever would toss the first stone, how else is the selection out there? That special one that really inspired you in form and function? It looks about the right size to be a natural bottle opener, it's Sikhote, and Steve hasn't bothered the list lately other than by pumping $500 into the economy. Nice adquisition. It looks nothing like a fantasy 'zoomorphic' dragon to me, not even a Seahorse (naturally regmaglypted). Bullet-shaped orientation is more common than boomerang-shaped as far as I have seen, and with stones- forget it, and it is interesting that they are both used in warfare, and for those reasons I would be glad to have it, too. Hope you hear from the numerous Sikhote fans. Here is another beauty for the discriminating S.A. (Russia) enthusiast with nicer pictures. Enjoy! http://207.56.99.163/sa168.htm Best wishes and good health, Doug ----- Original Message ----- From: "Mr EMan" <mstreman53 at yahoo.com> To: <meteorite-list at meteoritecentral.com> Sent: Monday, October 29, 2007 8:45 AM Subject: Re: [meteorite-list] Steve's 150-gram Dragon piece > Steve Arnold (Chicago) wrote: > >> "...one of the most beautiful and oriented meteorites that I have >> ever seen. > > OK...
