Cladogram of Archosauria

Congratulations! You found the Secret Cladogram of Archosauria! There's actually nothing secret about it. The information here is contained within the main chordate cladogram and the dinosaur cladogram, making this one effectively redundant. But since it took me so damn long to write the code for this page, I wanted to keep it on my site somewhere. Note the rudimentary style of branching structure employed here. If you are underwhelmed by this page and would like to go home, click here. Otherwise, enjoy.
