	Obscure stuff, but definitely relevant, particularly as a warning  
that one can not be too cautious when assessing the possible Mars fossils  
claims.  Here are some citations:

Staplin, F.L., 1962.  Microfossils from the Orgeuil meteorite.   
Micropaleontology, v.8, p.343.

Timofeev, B.W., 1963.  Lebensspuren in meteoriten.  Resultate einer  
microphytologischen analyse.  Grana Palynologica, v.4, no.1, p.92-99.

Kremp, G.O.W., 1968.  Observations on fossil-like objects in the Orgueil  
meteorite.  Journal of the British Interplanetary Society, v.21, p.99-112.

Nagy, L.A.; Kremp, G.O.W.; Nagy, B., 1969.  Microstructures approximating  
hexagonal forms (and of unknown origin) in the Orgueil carbonaceous  
meteorite.  Grana Palynologica, v.9, no.1-3, p.110-117.

	The one by Timofeev is particularly, uh, "interesting".  :-)  Five  
new species are proposed and assigned to terrestrial (!) acritarch genera,  
and one is assigned to a pre-existing terrestrial acritarch species (!!).   
No, I am not joking.  I wonder if this means Timofeev's species names have  
priority over any possible Martian ones?  :-) :-) :-)
