Cretaceous Period

Detailed Overview

The Cretaceous period was the last and longest period of the dinosaur era, ending with the famous mass extinction that killed all non-avian dinosaurs. This period saw the first flowering plants (angiosperms), which rapidly diversified and transformed terrestrial ecosystems. The period featured some of the most famous dinosaurs, including Tyrannosaurus Rex and Triceratops. The extinction at the end was caused by an asteroid impact and massive volcanic eruptions, leading to the rise of mammals in the following era.
