In order to unlock the Cenozoic Dome, regardless of what level you are, you will need to acquire and hatch a Cenozoic creature first. Any creature will do. You can get Cenozoic creatures from card packs, the prize drop, prize wheels, battle events and occasionally tournaments! Once your Cenozoic creature has hatched, the dome will be unlocked right away!
My Cenozoic Dome is still locked and I've levelled up beyond 19!
