  • Of, relating to, or designating the earliest of the three geological eras characterized by abundant fossil remains (the first era of the Phanerozoic eon), between about 570 million and 245 million years ago, following the Proterozoic eon and preceding the Mesozoic era, and marked by the diversification of multicellular plants and animals in both aquatic and terrestrial habitats.

    The classification of animals is that used in the 'Cyclopædia of Anatomy and Physiology,' and we include in the term 'Palæozoic,' all the generally argillaceous and araneceous strata between the mica schist and the old red-sandstone.

    The geological formations have sometimes been grouped and classified, in accordance with the predominant types of animals and vegetables which lived at the time of their depositions. The periods have accordingly been designated as- protozoic (protos, first; and zoe, life;) the period in which are found the first forms of animated existence; mesozoic (mesos, middle; and zoe, life;) the period of intermediate forms of life; and cainozoic (kainos, new; and zoe, life;) the period of most recent living forms.

    We are accustomed to group all geological epochs under three great sections, the Palæozoic, or oldest, the Mesozoic or middle, and the Cainozoic, more commonly termed Tertiary, or newest

    Palæzoic Period (Ancient Life)

    Page, D. (1854). Introductory Text-book of Geology: 39.


    Fossiliferous, or Sedimentary, rocks are divided into three great series,-

    The Palæozoic (most ancient forms of life), or Primary.

    The Mesozoic (middle life period), or Secundary.

    The Neozoic or Cainozoic (more recent forms of life), or Tertiary.
