Meteorites do not have flat parts. I have been sent photos of meteorwrongs with four kinds of flatness.
- Layered sedimentary rocks that are flat on two sides. Meteorites are not layered.
- Some igneous rocks fracture along planes leaving a flat surface or two parallel flat sides.
- Man-made things that were sawn or forged with a flat side.
- Man-made things that started out molten and then solidified in a confined space so that the top is flat or was poured onto a concrete or other hard floor so the bottom is flat.
All of the photos below were sent to me by persons inquiring whether the objects were meteorites. Note that none of these things has a fusion crust.
