Fossil Pokémon in 7 km Eggs
There is no official end date for this event. I’ve put in a placeholder until we know an end date.
Starting NOW, any newly obtained 7 km Eggs will hatch a Fossil Pokémon. The pool of possible fossil Pokémon is Omanyte, Kabuto, Aerodactyl, Lileep, Anorith, Cranidos, Shieldon, Tirtouga, and Archen.
There is no announced end date but this is likely a temporary egg shake up.
Fossil Pokémon have been removed from 2, 5, and 10 km Eggs. They will exclusively hatch from 7 km eggs for this event.
In 7 km Eggs
Riolu has been been moved to 10 km Eggs. It unclear if Alolan or Baby Pokémon have been moved as well. (My guess they’re temporarily unavailable for this event.)
