Cretaceous World

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

Plant Life:

The  early cretaceous landscape abounded in conifers and ginkgoes,as in Jurassic times. Later in this period, flowering plants and shrubs became common, as did trees such as Oaks, maples, and walnuts .

Dinosaur life:

Small herbivores were more common in this period. Carnivores like Baryonyx may have lived on fish, while tyrannosaurids probably fed on other dinosaurs.
