Pleistocene Park Apocalypse

Dinosaurs in apocalypse settings are frigging awesome. Don't try to fight me on this one. Cretaceous World park complexes around the world gone wrong and you know some dinos are gonna survive and some will be mutants or giants. Then of course there are Pleistocene Worlds with various time zones. Of course, these animals are a bit fake with frog and squid DNA used in the mix but the real cheats are the robotic animatronic dino parks and android dinosaurs used by inauthentic parks but at least they cant breed. Ok, some labs and weirdos with the specs can just make and mod them.

Cadillacs & Dinosaurs is a great comic with mechanic shamen and prehistoric life returns from some biochemical accidental release and the next thing trilobites are back. A devolution virus bioweapons might have been a war weapon responsible for these creatures.

Obviously, due to marketing, time periods and locations of parks give way to exiting attractions over science.
