Why this rock is probably not a meteorite:

It might be. If it is, it's an oriented stone that came through the atmosphere with the left side first. If someone out there has ever seen a meteorite with this shape, please let me know.
What is it?

It's impossible to say from the photograph. It could be a hematite concretion.
