The English version of Fossil was originally planned to be released around January 2000 (based on original Jungle estimates). But because Jungle was pushed ahead, Fossil was pushed ahead as well.
Wizards of the Coast once again increased the set size by producing holographic and non-holographic versions of the rare cards; however, they removed the Mew card that was in the Japanese set. Mew would later reappear as Wizards Black Star Promos #8 (non-holographic) and #9 (holographic).
Fossil completed the transition of the first 150 Pokémon (151 in Japan with the inclusion of Mew) to card form.
