Why this rock is probably not a meteorite:
It looks something like a lunar breccia, but the big "clast"
on top has a coating or rind, and that doesn't happen in lunar breccias.
Also, the aspect ratio (length/width) of some of the "clasts"
is much too high for any lunar breccia (typically less than 3 to 1).

What is it?
It's from New Mexico. It's some kind of volcaniclastic rock, that
is, it's igneous, not sedimentary. See no. 118.
