All of the photos below were sent to me by persons who wondered whether the rocks were meteorites. None of these rocks is a meteorite. Meteorites do not look like this. None of these things has a fusion crust. I suspect that nearly all of them are sedimentary rocks. Several are concretions where minerals precipitated from a solution around a core to form a sphere. A couple look like layered rocks that weathered to conical or spherical shapes leading to concentric circles.
