Christopher Columbus sailed to America and found dinosaurs but this caused a shift that changed the climate around the globe dramatically. After many years the dinosaurs slowly died off and the pilgrams domesticated sabertooth tigers and mammoths iirc.
People in here acting like there's been tons of dinosaurs in video games... fuckin' a. It's been nearly a decade since we've had a AAA dinosaur experience. Also the poll from back in the day for FarCry specifically mentioned dinosaurs. So if there are no dinos in this game, I'm gonna be bummed the hell out.
