AI overview

The Paleozoic Era is the first major division of Earth's most recent 538 million years of history, spanning from about 539 to 252 million years ago and subdivided into six geological periods. It matters because it represents a foundational chapter in the history of complex life on Earth, bridging the time between the emergence of most animal groups and the rise of the age of dinosaurs.
