Planet Erde - Das Leben bahnt sich seinen Weg

Earth was inhabited by many wondrous creatures throughout the Permian period as massive geologic changes finally allowed life to thrive on land and sea.

After the Permian period, evolution and extinction produced the first dinosaurs: plesiosaurs and pterosaurs, who dominated land, sea and air until another period of extreme volcanism killed roughly 75 percent of all species.

The Cretaceous was the golden age on ancient Earth, with magnificent and terrifying dinosaurs ruling the land until an asteroid collision.
