Why this rock is probably not a meteorite:

1) No fusion crust.

2) The original surface is very rough, not smooth, like a meteorite.

3) It's full of holes.  
What is it? This is the sawn face of a terrestrial basalt containing vesicles - holes previously filled with the expanding gasses that drove the volcanic eruption. Such rocks are common in volcanic areas on Earth.  Note that some vesicles are elongated, which indicates that the gas-bubble filled magma flowed before solidifying. The filled vesicles are called amygdules. They contain whitish minerals deposited in the voids from aqueous solutions that passed through the rock after it solidified.
