   Thanks for the answer. I makes a lot of sense!   
   >From this point of view I understand much better the story, and how   
   different it is than hunting fragments in places where a single well known   
   meteorite has fallen (such as in Sikhote-Alin, Siberia).   
      
   So, as there are quite few of information from DaG 488, could I guess that   
   at least it hasn't been recognized as a piece of Mars or the Moon, and that   
   it most probably comes from some asteroid...   
      
   Thanks again, Eric
