Paleozoic Era

A Paleozoic Era is a geologic era of the Phanerozoic Eon.

• Context:
  • It can be preceded by the Neoproterozoic Era of the Proterozoic Eon.
  • It can be followed by the Mesozoic Era.
  • It can (typically) include
    1. Cambrian.
    2. Ordovician.
    3. Silurian.
    4. Devonian.
    5. Carboniferous.
    6. Permian.
  • …
• See: Permian–Triassic Extinction Event, Treptichnus Pedum, Hindeodus Parvus.

  • The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name Paleozoic (pronunciation: /ˌpæli.əˈzoʊ.ɪk,_ʔi.oʊʔ,_ˌpeɪʔ/ Template:Respell;Template:RefnTemplate:Refn) was coined by the British geologist Adam Sedgwick in 1838).

    It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest):

    1. Cambrian.
    2. Ordovician.
    3. Silurian.
    4. Devonian.
    5. Carboniferous.
    6. Permian.
  • The Paleozoic 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. The Cambrian 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. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean but eventually transitioned onto land, and by the late Paleozoic, great forests of primitive plants covered the continents, many of which formed the coal beds of Europe and eastern North America. Towards the end of the era, large, sophisticated synapsids and diapsids were dominant and the first modern plants (conifers) appeared.

    The Paleozoic Era ended with the largest extinction event of the Phanerozoic Eon,the Permian–Triassic extinction event. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover.

    Recovery of life in the sea may have been much faster.
