Why this rock is probably not a meteorite:

This one also has a good story. It was found in the desert of Oman, a place where thousands of meteorites have been found.

When I showed thius to a geologist colleague, he said "that's a ventifact." A ventifact is a rock that's been sculpted by sand-carried by wind. Even a meteorite could be a ventifact, and some from Oman appear to have been so sculpted (see photo of Dhofar 465).

This thing is dense; the specific gravity is 4.6, to high for any stony meteorite and too low for an iron meteorite. It's just slightly magnetic and leaves a gray streak
 
What is it?

We don't know yet, but it must be an aggregate of some oxide or sulfide mineral, but not magnetite.
