Well, once you spell virginia correctly, it works. I went there and >>SIGH<<
indeed found yet another theropod cladogram. This prompted me to work up a
"consensus cladogram" of all known theropod cladograms published to date. Not
surprisingly, the resolution dropped somewhat (for best results, use a
monospaced font):

                  |---------------------------------------------Herrerasauria
                  |---------------------------------------------Lagosuchia
                  |---------------------------------------------Ceratosauria


                |---------------------------------------------Neoceratosauria
                  |---------------------------------------------Alvarezsauria
                  |---------------------------------------------Spinosauria
                  |---------------------------------------------Carnosauria
Theropoda---------|---------------------------------------------Coeluria




              |---------------------------------------------Ornithomimosauria
                  |---------------------------------------------Tyrannosauria
                  |---------------------------------------------Avimimiformes



               |---------------------------------------------Oviraptorosauria



               |---------------------------------------------Deinonychosauria







           |---------------------------------------------Archaeopterygiformes

                 |---------------------------------------------Protoaviformes
                  |---------------------------------------------Avialae

(No taxonomic significance is to be attributed to the ordering of the subtaxa
down the page; it is >>entirely<< arbitrary...)
