When I started a new game I spawned in a rocky beach with a reasonable amount of trees rich with dodos and dilophosaurus, as I got better and better at surviving the dodo and dilophosaurus amount in the shore fell drastically and therizinosaurus spawned, later the triceratops disappeared along with the igaunodons, new creatures appeared for a short period of time and some raptors wandered out of the jungle and nearby river. Does anyone else have this problem? This is an example of environmental changes on earth because I am slowly destroying the dead area and I’m moving to a safe shoreline across my megalodon infested bay.
