fossil record geologic time scale
The division of geologic time that makes up about 88 percent of Earth's history is called the Precambrian eon. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago.
The Earth's history is divided into geologic time periods, with the largest unit being eons, which are further divided into eras, periods, epochs, and ages. The current eon we are in is the Phanerozoic eon, divided into the Paleozoic, Mesozoic, and Cenozoic eras. Each division represents significant changes in Earth's geological and biological history.

The geologic time scale helps to organize Earth's history into manageable segments based on significant events and changes. It allows scientists to study and understand the timing of key geological and biological events, such as mass extinctions or the formation of mountain ranges. By providing a framework for organizing this vast expanse of time, the geologic time scale aids in our understanding of Earth's evolution and the processes that have shaped our planet over billions of years.
