Why this rock is probably not a meteorite:

Again, it's not smooth on the outside. Also, its consists of long, noodle-like things. Meteorites don't have any linear features like this.
What is it?

It came from southern Georgia and was found on a road. It's magnetic. I suspect it some kind of iron-oxide concretion, mainly composed of magnetite.
