So I was looking up maps of some zoos I know for inspiration and I was surprised to find one that I like, but haven't been to in probably a decade, has about 1/5 of its land dedicated to a Jurassic Wing. And if you live where I do, you'll find dinosaur museums and parks aren't uncommon.
I don't need dinosaurs as animals in the game, but like some people above said, some scenery and themed objects would be nice. Animatronic dinosaurs and stuff, could be fun to make a Jurrasic section in your park.
