PaleoNet: Mineralogy of fossil remains

[brcgranier at free.fr]

Dear PaleoNetters,

here attached are the new version of the table to compare with its 60 
years old original version.

Special thanks go to Phil Bock, David Campbell, David A.T. Harper, Roy 
E. Plotnick, and Thomas E. Yancey, who kindly provided some missing 
information.

Should you think of any further improvements, please do not hesitate to 
let me know.

=) Bruno Granier
