Why this rock is probably not a meteorite:

This rock is from central Minnesota, another place that was covered by a glacier 15,000 years ago. Again, it doesn't have a fusion crust. Note that there's a linear or planar orientation to the knobs. Meteorites don't have layering or linear orientation of any features.
  
What is it?

This rock is probably another glacial erratic, though I don't know what kind of rock it is.
