The left half shows a timeline of Earth’s geologic history which is split into Eons, Eras, Periods, and Epochs and how many millions of years ago (MYA) these occurred.

The BGS geological timechart provides colourful reference material for use in schools, colleges and at home, setting out the geological timescale and geochronological terms we use at BGS.

Including the diagram in our first chapter on Geological Time. Below we have provided the same information that is in the time scale diagram but this time in a table format.

The table of geologic time spans presented here agrees primarily with the nomenclature, dates and standard color codes as set forth by the International Commission on Stratigraphy …
