Precambrian Era, Paleozoic Era, Mesozoic Era, Cenozoic Era
The Precambrian.
Periods
eras
The four major divisions of time, from longest to shortest, are eons, eras, periods, and epochs. Eons are the largest intervals, encompassing significant geological and biological changes. Eras are subdivisions of eons, followed by periods, which further break down eras, and epochs, the smallest divisions, provide even finer detail within periods. These divisions help scientists organize Earth's history and understand the evolution of life and geological events.
The largest divisions of time on the geological time scale are eons, which are the longest units of time and are further divided into eras. The current eon, the Phanerozoic Eon, is divided into three eras: Paleozoic, Mesozoic, and Cenozoic. Each era is further subdivided into periods, epochs, and ages.
These are put in order of older to newer. Precambrian, Paleozoic, Mesozoic, Cenozoic.
The geologic time scale provides a timeline of Earth's history, dividing it into periods based on significant events and changes in the planet's environment. The major divisions of geological time are eons, eras, periods, epochs, and ages, each reflecting different intervals of time with distinct characteristics and geological events.
I have never heard of it- i think you mean the Paleozoic Era, which is one of the four main divisions of geological time, and it spanned from 545-250 mya (million years ago). Glad to help! :D
Eon - Phanerozoic (most distant) Era - Cenozoic Period - Quaternary Epoch - Holocene (most recent)
The four major divisions of time, from longest to shortest, are eons, eras, periods, and epochs. Eons represent the largest intervals, spanning billions of years, followed by eras, which last hundreds of millions of years. Periods are subdivisions of eras, lasting tens of millions of years, while epochs are the shortest divisions, typically lasting several million years. This hierarchical structure helps scientists organize Earth's geological history and the evolution of life.
Cenozoic Mesozoic Paleozoic Precambrian
Geological time eras are divided into periods, which are further divided into epochs. Each era represents a significant span of time in Earth's history, characterized by distinctive geological and biological events. These divisions help scientists organize and study the vast expanse of Earth's history.
