My classification of the dinosaurs
This is my tentative non-cladistic classification of the dinosaurs.
In order to accomodate the diversity I have bumped the order-group
taxa up one half step. That is, traditional suborders are orders,
and so on.
The principle source I used is:
Olshevsky, George, 1991, A Revision of the Parainfraclass
Archosauria Cope, 1869, Excluding the Advanced Crocodylia.
Mesozoic Meanderings #2
I have also made use of:
Weishampel, David B., P. Dodson, & H. Osmolska, eds, 1990
The Dinosauria, University of California Press
Paul, Gregory S., 1988, Predatory Dinosaurs of the World.
New York Acadamy of Sciences, Simon & Schuster
