I have checked that these links exist (last checked December 2010). At least at one time they were all fossil related. While the link existence check is automated, the content check is not. Even pages that persist may have their content deleted, get co-opted, etc.

If you find a problem link, let us know.

Times have changed since I first compiled this list. Google is now available. If you want particular information, e.g. "trilobites", I would go there first. The first two sites returned by Google are the Wikipedia entry (another good place to start) and the "Guide to the Orders of Trilobites"listed below!

Note:

These pages have not been generally reviewed, but some particularly informative sites are marked by a  .
