All the photos below were sent to me by people asking if the objects might be meteorites. All have unusual shapes. My late mother-in-law might have said, “That rock is goofy.” Although some iron meteorites have unusual shapes, stony meteorites do not have goofy shapes. Nearly all of the of the objects below are sedimentary rocks or minerals. Many of them are hematite concretion or nodules. One looks like molten metal poured into water and another appears to be an arrowhead made from a natural rock.
Bottom line: If it is stony (not iron) and has a goofy shape, then it did not come from outer space.
