I dont want to get involved in the thread about what
the classification is (I will be pretty happy no
matter what the proposed options are) but can somebody
explain to me why its called a "Fossil" meteorite?
I realize that the term "fossil" can be loosely used
to describe pretty much any old stuff (You could even
call a living person a "fossil" meaning a person with
old fashioned stubborn views) but given that this is a
scientific classification I would expect more rigid
use of the term in a scientific standpoint.
To become fossilized means that over a long peroid of
time (Usually millions of years) actual organic
material gets replaced by stone so that when you have
a fossil such as a dinosaur tooth, fossil shark tooth
or ammonite you actually have a rock and not a real
creature. No DNA can be extracted since its only a
rock. Thats why we dont even know if dinosaurs were
warm or cold blooded. We are only studying a rock when
we study dinosaur fossils - not a real original
artifact. So called mammoth tusk fossil or 10,000 year
old fossil buffalo bones are not really a fossil since
you get the original item - not a fossilized version.
Fossil insects and bacteria in amber is often not
fossilized even if millions of years old.
But the meteorite in question has not been fossilized.
The chrondrules are real chrondrules and not a
replaced with stone chrondrule. You are not getting a
calcified stone when you buy this "fossil" meteorite.
You are getting a real original meteorite (Even if
highly weathered and oxidized).
I realize that dealers (Including myself) call it a
fossil or paleo meteorite but can somebody explain to
me why it should be called a fossil (Or Paleo)
meteorite?
Thanks
DEAN
