Description

 * 12 000 years ago: At this time, glaciers were ravaging the landscape. Herds of Mastodons travel across the landscape and the now small Hudson river while predators like the Short-Faced Bear search for preys and herbivores like Castoroides live in swamps.
 * 80 million years ago: The city is submerged by the oceans. There live the giant turtle called Archelon whom they have been hunted by Tylosaurus.
 * 185 million years ago: The theropod Dilophosaurus became the apex predator after the fall of crocodilians predators.
 * 200 million years ago: New York is now a desert. First dinosaurs like Coelophysis are being hunted by apex crocodilian predators like Postosuchus. Volcanic activities also happen.
 * 450 million years ago: New York is again submerged by the ocean, except now there are sea scorpions called Eurypterus and ammonites (presumably Dawsonoceratidae).
