Why this rock is probably not a meteorite:

The finder was intrigued by the surface texture of this rock, which she likened to a "brain." But, of course, this rock doesn't have a fusion crust or a smooth surface, so it can't be a meteorite.
What is it?

Don't know. Probably some kind of sedimentary rock that has weathered unevenly. It looks something like meteorwrong no. 096.
