Michigan Meteor: How do you know if you've found a meteorite?

As meteor madness continues across metro Detroit, some people may set out to find their own piece of space treasure.  But, how do you know if you've stumbled across a meteorite? Full disclosure: It may not be easy.  According to Geology.com, meteorites may have certain characteristics that can set them apart from other ordinary rocks. While there are a variety of meteorites, look for identifiers like thumbprint-like indentations, an ash-like crust, shiny flakes and/or flow lines. The site notes that most meteorites are rich in iron and nickel, so -- while you shouldn't use it as the only indicator -- try a magnet test. Another thing to consider: weight. Meteorites reportedly will usually feel heavier than ordinary rocks.
