| There are many excellent books on historical geology, paleontology, individual periods of geologic time and other aspects of stratigraphy. Some of this information on the history of Earth’s surface and its life is now available on websites which are continuously being updated and enhanced. Some selected ones (biased slightly toward North America) are: |

Geologic Time Scale (by Liam Piesley)
-- https://liamp.uk/timescale/ --
Interactive version of the geologic timescale that shows each era true to scale and adjusts to show the relative length of each time period with short AI produced descriptions of the stages etc.. Alongside the interactive timescale chart I have also added pole reversals (from data in Geologic Time Scale 2020), a map showing how the continents moved during the Phanerozoic and a map with GSSP locations.
It works best on a desktop computer |

Palaeos: The Trace of Life on Earth (compiled and maintained by Toby White)
-- http://www.palaeos.com/ --
and others it references at end of each period.
There is also a WIKI version being compiled at
-- http://www.palaeos.org.
The Palaeos suite has incredible depth and is written for the general scientist. |
