I STRONGLY urge you to read up on the basics of the process and procedure
first before attempting to do a dinosaur cladogram.

I don't know if J.O. Farlow & M.K. Brett-Surman's 1997 _The Complete
Dinosaur_ (Indiana University Press) is available where you are now, but
Ralph Chapman has a chapter on "Technology and the Study of Dinosaurs" that
discusses the operational end of things.  (The chapter by myself and
Brett-Surman on "Taxonomy and Systematics of the Dinosaurs" discusses
cladistic classification).

There are some GREAT websites out there talking about phylogenetic
systematics in general and dinosaurs in particular.  A good starting point
is the University of California Museum of Paleontology's website on
phylogeny.  Go to:


and look around there.  (I think that is the proper URL).

Hope this helps.
