Must be rather fresh due massive reheated rim? |

That sign says Bella Roca is the "separated at birth" meteorite from this Costilla Peak which Buchwald did not mention. The location of the find is not documented at all and could easily have been transported. The bulk nickel between Bella Roca and Costilla Peak according to Buchwald is different, though the ratios or ranges may place both in the similar IIIABs classification. I don't think the display at AMNH was discussing pairing unless you want to say all IIIAB medium octahedrites are paired across the globe, so I think that display could be improved for educational purposes. And separated at birth - that would be over 4 billion years ago ;-) |

I'll bet it had the much desired meteorite "organic" smell to it too. :/ |

Yes, Anne, very nice iron, and, as Buchwald also states: "very similar to ... Henbury ...". Buchwald also writes that some of its troilites show multiple twinning and brecciation. |
