Cretaceous world

In the Cretaceous period, North America, Europe, and Asia were part of a much larger continent called Laurasia. Herbivorous dinosaurs, which included the ceratopsians and the hadrosaurids, browsed among marshy lowlands. The giant sauropods became rare. In the late Cretaceous the terrifying tyrannosaurids appeared. They were the top predators until the extinction of the dinosaurs, at the end of this period.
