The Palaeozoic (or Paleozoic) era is the earliest of the three eras of the Phanerozoic. Its name means early life. It lasted from about 541 to 252 million years ago (mya) and ended with the greatest extinction event, the Permian–Triassic extinction event. The Palaeozoic was the beginning of plants and animals. In particular, fish dominate the Palaeozoic.
