Why this rock is probably not a meteorite:
The finder thought that this rock was a meteorite because he thought
the coating was a fusion crust and because
the rock is rounded. A meteorite this large would have regmaglypts;
this rock doesn't have any. The finder sent a chemical analysis that
he had done. The composition is inconsistent with any kind of meteorite
(concentrations of alkali elements too high, concentration of chromium
too low, Fe/Mg ratio too high, others).

What is it?
We don't know. Unfortunately, there are many processes on Earth that
produce coatings on rocks.
