The "Super" Family Tree of Dinosaurs

Recently published in the Proceedings of The Royal Society, Biological Sciences, Volume 275 Number 1650 on November 7, 2008.

This is over my head, but this radial family tree shows the diversity of dinosaur species.  It's used in the article to help challenge the theory that dinosaurs went through a rapid decline during the Cretaceous period.  A brief summary is online over at The New Scientist.
Furthermore, we conclude that dinosaurs did not experience a progressive decline at the end of the Cretaceous, nor was their evolution driven directly by the Cretaceous Terrestrial Revolution (KTR).
Thanks for the link Michael!
