The Palaeozoic Era (from the Greek words "palaios" (παλαιός), "old/ancient" and "zoe" (ζωή), "life", meaning "ancient life") is the earliest, and by far the longest, of three geologic eras of the Phanerozoic Eon, spanning ~541-252.2 million years ago.
It is subdivided into six geologic periods (from oldest to least old): the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian. The Palaeozoic comes after the Neoproterozoic Era of the Proterozoic Eon, and is followed by the Mesozoic Era.
The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. Out of all the three eras, it was the one with the greatest changes.
The Cambrian Period witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Vertebrates evolved during the early Palaeozoic.
Life began in the ocean, but eventually spread onto land.
By the late Paleozoic, various forms of organisms dominated.
Great forests of primitive plants covered the continents, many of which formed the coal beds of Eurasia and North America.
Towards the end of the era, large, sophisticated animals were dominant and the first modern plants, conifers, appeared.
The Paleozoic Era ended with the largest mass extinction in Earth's history, the Permian–Triassic extinction event, which destroyed ~95% of all life on Earth.
The effects of this catastrophe were so devastating that it took life millions years to recover.
