north american dinosaurs

At the end of the dinosaur age, gigantic beasts roamed the southern half of the North American continent. From Utah to Texas and New Mexico, these giants shook the earth under their immense weight, towering above predators and neighbors alike. It was the reign of Alamosaurus, America’s biggest dinosaur.

We all know Tyrannosaurus rex as North America's biggest and most terrifying land predator. It ruled the continent 66 million years ago, dominating its prey and rivals with its 9-ton bulk and bone-crushing jaws. However T. rex was not exactly as American as we once thought.
