[meteorite-list] When a fall turns out to be a find not recently fallen.

[Francis Graham]

Dear List,
   It is possible that a meteorite might be seen to fall, and then the
site of the fall investigated and a meteorite found; but upon later
analysis the weathering, etc. reveals that the meteorite collected
couldn't possibly have been the witnessed fall, but instead a
coincidental independent find.
    My question, has this ever happened in real life?
