Dinosaurs, and a rich variety of land based prehistoric life, achieved surprisingly massive sizes in comparison to present day life. This ability of dinosaurs to achieve gigantic sizes conflicts with studies which indicate that the largest of today's animals have reached their maximum size.

The web site gives a brief introduction to some of the main concepts behind the theory. There are also links to other sites about gigantic dinosaurs and their lifestyles, a Comments Section, a Quiz and some suggestions for Further Reading.
