Why this rock is probably not a meteorite:

1) No fusion crust.

2) Too full of holes. Meteorites don't have vesicles like this.

3) The rock looks glassy or very finely crystalline. Most meteorites are crystalline - they're composed mainly of mineral grains - but the crystal size is large enough to see individual grains with the naked eye (see ordinary chondrites). Some have glassy portions, but none are all glass.
What is it?

Can't tell from the photo.
