So really... what is Fossil? Here are the facts:
Set Size: 62 in the US, 48 in Japan
In the US, Fossil was expanded (yet decreased) to 62 cards, since Wizards did the holo/non-holo deal again AND they took Mew out of the set.
Set Order: 3rd set in the US, 3rd set in Japan
Release Date: October 10th, 1999 in the US; ??? in Japan
Fossil was originall planned to be released in the US around January 2000 (based on original Jungle estimates). But because Jungle was pushed ahead, so was Fossil.

Goodies:
Wizards had decided to take Mew out of
Fossil and turn it into a Pokémon League Promo
card. At first, people HATED this move.... but then it was
those same people who walked out of the Pokémon
League with 11 of them.
Symbol:
The symbol for Fossil was a claw.
