A very deatailed site describing the changes in life over geological time. The site looks a little dated and the navigation is not straight forward, but well worth a dig around. Better still most of the material can be used freely for non-commercial purposes.

A very comprehensive site dedicated to the humble trilobite. An excellent resource on all things trilobite.

Gallery, articles and news (although it's not been updated for a while) on all aspects of dinosaurs.

A site detailing the dinosaurs of the Isle of Wight, with fantastic information and pictures. Well worth a visit.

This Web Site brings information about one particular group of these fascinating prehistoric marine reptiles to the attention of a wider audience whilst also being useful to anyone already interested in the Sauropterygia: plesiosaurs and their kin.
