As you wander around the park, you start to notice a prehistoric theme. There are boulders scattered around the place, and several of them on closer inspecion seems to have fossils in them. The paths are laid with rocky slate slabs, and are lined with ferns. There are also palm trees and monkey puzzle trees.
Looking around the park you realise you can't see any buildings outside, not even tall skyscrapers. You suppose it must be due to the elivation, but it still feels odd. It's also gotten warmer.
Then you came across two sets of footprints. One is of a large dinosaur, the other is bare and human, but bigger and larger than your own. They're clearly artificial, but look so lifelike.
