How to complete all Adventure Week 2023 Fossil Collection Challenges in Pokémon Go

Better get digging for some fancy rocks.

Have you ever gone outside and collected rocks? Well, that’s what Niantic wants you to do for Pokémon Go’s Adventure Week 2023 event since all four Collection Challenges revolve around Fossil Pokémon.

From July 27 to Aug. 2, players will encounter more Rock-types in the wild and raids. This includes Mega Tyranitar making its debut in Mega Raids and plenty of Fossil Pokémon running around—which tied directly into the Collection Challenges and Timed Research too.

In fact, every first-stage Fossil Pokémon, including Aerodactyl, is spawning in the wild more frequently. Tyrunt and Amaura can also be encountered as Shinies for the first time too. 

You will want to catch as many Fossil Pokémon as possible during this event, both because they are rare Pokémon and since they will net you even more rewards in fossil-themed Collection Challenges. There are four different ones in total, all tied to a pair of Fossil Pokémon you can find in Gen I, Gen III, Gen IV, and Gen V—the Gen VI fossils are just featured Pokémon so don’t worry about it since you will encounter plenty of them anyway.
