  1. Proterozoic means first life - It is the time period in the late Precambrian when life first appears in the fossil record.


  2. The Proterozoic (pronounced /ˌproʊtərəˈzoʊɪk/) is a geological eon representing a period before the first abundant complex life on Earth. The Proterozoic Eon extended from 2500 Ma to 542.0 ± 1.0 Ma (million years ago), and is the most recent part of the old, informally named ‘Precambrian’ time.

    The Proterozoic consists of 3 geologic eras, from oldest to youngest:

    Paleoproterozoic

    Mesoproterozoic

    Neoproterozoic

    The well-identified events were:

    The transition to an oxygenated atmosphere during the Mesoproterozoic.

    Several glaciations, including the hypothesized Snowball Earth during the Cryogenian period in the late Neoproterozoic.

    The Ediacaran Period (635 to 542 Ma) which is characterized by the evolution of abundant soft-bodied multicellular organisms

  3. Beginning of life

  4. Former life

    Literal translation is first animal
