Links to other Earth History websites

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:

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