We have 3 kinds of “themes”
What if there is a lagoon?
The idea is there is a large fence around the shores next to the cenozoic dome.
The aquarium (were the mosasaur is) and the cenozoic dome doesn’t have escaping creatures.
What if the lagoon, is the second place where creatures can escape?
mangrove wins from open sea, open sea wins from shallow sea, shallow sea wins from mangrove.
Like the aquarium, the lagoon is home for several aquatic/semi aquatic animals from different times.
Spinosaurus gen 2
Instead of the classic jurassic park style, what if spinosaurus gen 2 is the scientific accurate one (long neck, short backlegs, long tail)?
The spinosaurus gen 2 is a mangrove creature.
Its also a VIP-creature with royalty points (like hainosaurus and tylosaurus, everyone get the chance to get it)
