Why this rock is probably not a meteorite:

This is a 10-lb rock that someone sent me. There's no fusion crust and the surface is very rough. Ther's nothing about it that suggests it's a meteorite.
  
What is it?

We're not sure. The rock gave a gray streak, but it's not at all magnetic, so it can't be magnetite. We think its a manganese oxide nodule. It was found in Arkansas.
