Three eras of the Phanerozoic Eon.Carboniferous - 359.2-299 million years ago - Plants Covered the Earth.Devonian - 417-354 million years ago - The Age of FishSilurian - 443-26 million years ago - Plants Move Onto Land
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
Geological eras can be divided into periods, epochs and ages.
The Cambrian Period is divided into three eras: the Early Cambrian, Middle Cambrian, and Late Cambrian. These eras refer to different stages or time intervals within the Cambrian Period, which lasted from about 541 to 485 million years ago. Each era is characterized by different geological and biological events, including the diversification of early animal life.
The Precambrian Era can be divided into three major eras. These eras include the Hadean, the Archean, and the Proterozoic.
Eons, eras, and periods, from large to small.
There are 4 eras, and they are the Hadean, Archean, Proterozoic, and Phanerozoic eras.
There were several major eras of one party domination in American History. A couple of the eras was the Great Depression and the 1960s.

An era refers to a subdivision of geologic time that divides an eon into smaller units of time. The three major eras of environmental history are the Paleozoic, Mesozoic, and Cenozoic eras.
