Niantic have introduced some changes to how the Poke Eggs work in Pokemon Go. The most substantive change is that all Fossil Pokemon, aka Omanyte, Kabuto, Aerodactyl, Lileep, Anorith, Cranidos, Shieldon, Tirtouga, and Archen, are now going to hatch only from 7 km Eggs. None of them are going to be hatching from any other ones. Oh, and Riolu will be hatching from 10 km Eggs, which is a bit out of left field, but oh well. There’s no info on how long things will stay this way.
There is a shake-up happening with the Eggs in Pokemon Go. Specifically, it seems to revolve mostly around Fossil Pokemon, for some reason. Namely, Omanyte, Kabuto, Aerodactyl, Lileep, Anorith, Cranidos, Shieldon, Tirtouga, and Archen are now hatching exclusively from 7 km Eggs. Yes, no more Fossil Pokemon from the 2 km, 5 km, and 10 km Eggs. Which, you know, does have it’s advantages and disadvantages. One more change is that Riolu is now going to be hatching from 10 km Eggs.
Nobody really knows the cause of this happening, but the announcement on the Pokemon Go website assures us that “Spark is on the case,” which sure is a relief, I guess. Also, the post doesn’t mention any end date to this fossil fest. They do encourage you to “follow us on social media, opt in to receiving push notifications, and subscribe to our emails to stay updated,” which I really, truly refuse to do. I don’t care how long this lasts, and am not about to expose myself to tidal waves of spam to find out. That’s ultimately up to you, of course.
So, there you have it. For an unspecified length of time, you’ll have a reliable way to farm Fossil Pokemon. Gather as many 7 km Eggs as you can, and start walking; see what you can get. Good luck out there, fellow Trainers!
