Why this rock is probably not a meteorite:
This is an ugly one. It does have some kind of a coating that
resembles a fusion crust. The finder thought that it was a lunar
meteorite. It bears some resemblance, although we have not seen
large white clasts with stained exteriors in lunar meteorites.
We analyzed the rock and found it to contain 5% sodium as Na2O.
That's more than 10 times the concentration found in lunar rocks.
