Hey everyone! We are finished with digging through the APK and we have the updated spawn guide! There were not any local migrations (other than the addition of Bajadasaurus to parks) but there were some significant nest changes.
As far as we can tell the other 3 new creatures (Woolly Mammoth, Woolly Rhino, and Megaloceros) don’t spawn in the wild. The Mammoth is global right now but we aren’t sure how long that will be out. Here’s the article and all the relevant images for it!
