Actually, you wouldn't. What's missing is scale, and the Conception Junction crystals are substantially smaller than Brenham (or just about any other known pallasite, for that matter). We ran some comparisons, and I think the average Brenham crystal diameter was about 7.5 mm compared to only 4.5 mm for Conception Junction. It's strikingly obvious when you see it in person, and there are actually quite a good number of other aesthetic distinctions as well. Then there are the comparative analyses Dr. Wasson conducted, which are to some extent detailed in the monograph and are beyond conclusive in terms of dilenating Conception Junction's uniqueness from Brenham -- or any other known pallasite.

Nobody would blame Dr. Korotev for that mess of an article. Although, I think this entire affair can be laid to rest if some billionaire (or lotto winner) would simply step forward and take one for the team - I have a part-slice of El Hammami that I am willing to sell for several million dollars, thus setting the precedent required to make the article accurate. While we are on the subject of this new pallasite, I'd like to bring up a question that was briefly touched upon in the past - the visual similarity between Conception Junction and Brenham. I realize that the analysis has been done and these two meteorites are not the same. However, is there some chance that the two finds may be casually related in some way? To the eye, based on visual appearances alone, Brenham and Conception Junction do look similar. Now, I may be speaking from ignorance, since I have never seen a specimen of Conception Junction in person. I have only seen photos, but if I was presented with a slice of each in a "blind taste test", I would be at a loss to tell one from the other. Is there any possibility that these two meteorites might share the same parent body, or be launch-paired in some way? Are there any similarities in cosmic ray exposure data, terrestrial age, oxygen isotope (or any other compositional data) for these meteorites?
