[meteorite-list] what is this, really

1) In addition to not having a fusion crust, the object is
suspiciously non-lunar in that the clasts are too much all the same
size. Lunar regolith breccias are the closest lunar analogs to
terrestrial sedimentary rocks, and there is often a superficial
resemblance. In many (but not all) terrestrial sediments, however,
wind and water processes lead to size sorting so that the clasts are
all about the same size. There are no such sorting mechanisms on the
Moon. I've called this a "fractal" effect - it doesn't make any
difference what scale you look at a lunar regolith breccia, it always
looks the same. To me, in the rock in the photo (asphalt?), there
don't seem to be enough big clasts or small clasts, as, for example,
in ALHA 81005:

I've never heard of "meteorite expert" mentioned in the blurb.
2) Regarding text of Pluto news release: "Although astronomers
applauded after the vote, Jocelyn Bell Burnell -- a specialist in
neutron stars from Northern Ireland ..."
How many neutron stars are there in Northern Ireland?
