Why this rock is probably not a meteorite:

1)  The "crust" (top) is rust colored and its not shiny, like a fusion crust would be.

2) Inside (bottom) there are no obvious mineral grains and lots of pores.  Meteorites don't have this much porosity; most have no obvious porosity.
What is it? A piece of chert with a hematite coating.
