What is the paleozoic era
Series: Geologic Time Periods in the Paleozoic Era. During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains.Brachiopods have one of the longest fossil records of any multicellular animal. Brachiopods have been the most abundant bottom-dwelling creatures for three out of five global mass extinction events, all of which occurred during the Paleozoic era. They reached the peak of their diversity during the Devonian (Emsian Stage ~407-393 million years ago).Palaeozoic. 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 .
