Why this rock is probably not a meteorite:

I received these photos from another scientist who studies meteorites. They were sent to him by someone who found the objects in Kentucky.

They have some meteorite-like characteristics. The problem is that the wrinkles or lineations, which the finder interpreted to be flow lines, don't seem to run away from what should be the aerodynamically leading surface.
What is it?

I don't know. The finder found several of them in a small area. I suspect that they are some kind of iron-oxide concretion.

Please don't contact me about the meteorite you think you’ve found until you read this and this.
