Mesozoic Era
The Mesozoic Era covered the period from 230 to 65 million years ago.The Mesozoic Era is often known as the “Age of Dinosaurs” because these reptiles were the largest, the most powerful, and
the most conspicuous animals of the era. They basically dominated the Earth in the Mesozoic Era, which is divided into three periods: The Triassic, the Jurassic, and the Cretaceous Periods. These three periods exhibited their own unique share of dinosaurs, although the most conspicuous dinosaurs, such as the Tyrannosaurus Rex, were found in the Cretaceous Period, the
period in which dinosaurs were at their peak. The era also marked the birth of the Rocky Mountains, as well as the first birds, and mammals, both of which come from reptiles. Flowering plants (angiosperms) also first appeared in the Mesozoic Era. While the early Mesozoic was dominated by
unusual plants, the first modern gymnosperms began to appear during this era.The end of the Mesozoic Era is among the most famous events in the history of the Earth. 65 million years ago, 75% of the species on Earth went extinct, including the dinosaurs and ammonites, while the cause of the mass extinction remains controversial. During the Mesozoic Era, Pangaea began to split apart, and seas were forming between the continents. Europe was flooded during this era, and became dry again only during the Cretaceous period. A great rift zone helped drive Europe and North America apart, while Northern Africa also started to rift apart. Tectonic activity on the Earth was particularly active during the late Mesozoic Era, and there were many other events related to the shifting of the continents.
