Greg,

I'd like to hear more about this find. The MetBull entry says that
36 stones were found. Was there a meteorite-rich layer found in a
rock outcrop? Why didn't this get reported? If it ever got
transported in a stream, I'm surprised 36 stones were found in one
place. Can you tell us the rest of the story?

I have no problem with the term "fossil meteorite". There are many
similar uses of the term "fossil" in the earth sciences where it is
not referring to former life. However, I would think the term should
be reserved for cases of meteorites actually found in a rock or very
old sediments. Lots of meteorite finds are discovered below the
surface in soil or recent sediments (like Brenham!), or in stream
beds, but nobody calls them fossil meteorites. Others have clearly
been below the surface at one time (like every Antarctic meteorite),
but nobody calls them fossil meteorites either.

So let's hear the whole story!

Jeff
