Dr. Bob's Geologic Time Page

This page contains basic information about the geologic time scale and aids to learning the various periods and epochs. Mnemonic devices can be used to help remember the order that the periods and epochs occurred. The first letter of each word in the saying corresponds to the first letter of a period or epoch.

Events that transpired first took place longer ago; that is closer to the Precambrian. Please be advised that dates that appear on the geologic time shown here are only approximate.

Permission is hereby granted to use this picture if credit is given. I would like to express my apprciation to students and others who contributed to these lists.
