The Paleozoic Era is the first and longest era in the Phanerozoic Eon, and is one of three, the two other eras being the Mesozoic and Cenozoic. Paleozoic is derived from Greek and means "ancient life."

The Paleozoic lasted from roughly 542 to 251 million years ago, and is subdivided into six geologic periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The era began with the advent of multicellular life, and ended with the most severe mass extinction in Earth's history, destroying 96% of all marine species and 70% of terrestrial vertebrate species.

The Paleozoic Era saw the development and diversification of all the modern phyla and most of the groups of life we see today, including invertebrates, arthropods, fish, amphibians, and reptiles. Most groups of marine and terrestrial plants also arose and flourished during this time. Mammals and birds would not appear until the Mesozoic Era, which came after.
