Hi L.A., Listees,

of Allende is the old snuff ...
There are probably other carbonaceous chondrites of types similar
Dear Listees~
I was wondering if anyone knows what the oldest (as in
most primitive) meteorite is? I was thinking it was

There are two meanings to the word primitive that are in common use

Has any SEMARKONA [Indian fall of 1940, type LL3.0 (S2)] ever been distributed
to private collectors??? I very much doubt so. One of
