This Geologic Time Scale was originally designed for Spring 1998 "History of Life" course at San Francisco State University.
Since the site has wider appeal, I am trying to maintain and update it frequently. This is where you can help.
If you have a page or website that should be included in this directory, please send email to tsUpdate@es-designs.com.
In the email, please include the time period, a page title, location for the link (ie. General Info, Paleogeography, Fossils & Localities, etc), and the url of the link.
In the near future, I will be putting up a form to expedite the process.
Some of the links in the directory point to pages that were set up for specific earth science classes. These pages may have a limited lifetime on the web. As a result, you may find some broken links as you explore the Time Scale.
If you find a broken link, please send email to tsBadlink@es-designs.com.
In the email, please list the Time Scale page url, and the link that is broken.
I will try to fix broken links as quickly as possible.
If you have any other problems with the site, please send email to tsProblems@es-designs.com. In the email, please list the time scale page url and the nature of the problem.
Thanks!
