Phanerozoic Eon

The Phanerozoic Eon is the most recent geological time frame, lasting from about 541 million years ago to today. It is characterized by an abundance of fossil records and the rapid evolution of complex life forms, including plants, animals, and humans. The Phanerozoic is divided into three major eras: the Paleozoic, Mesozoic, and Cenozoic, each marked by significant biological and environmental changes, such as the emergence of land animals and the age of dinosaurs. Understanding this eon helps scientists study the history of life on Earth and the changes in its ecosystems over millions of years.
