After years of saying "This summer it'll be finished", my
website's Coelurosauria Cladogram section is finally done and ready for
viewing.
Many thanks to HP Mickey Mortimer, for providing me with the
results of his no-flight-related-characters analysis, the phylogeny of which is
used on my page.
Congratulations Grant! I appreciate you using my
analysis as the basis for the cladogram, and your use of the following sentence-
"The phylogeny is tentative, however, and may change." In the present
case, this is especially applicable. I'm in the process of making sure my
codings are accurate, so I don't really support any phylogeny at the moment,
but.... Removing the flight-related characters from my revision-in-prep
analysis creates a different phylogeny than your website-
+--Tyrannosauroidea
|--lots of basal coelurosaurs (compsognathids, Coelurus,
Ornitholestes, Scipionyx, etc.)
`--+--+--+--+--Alvarezsauridae
| | |
`--Avimimus
| | `--Ornithomimosauria
|
`--+--+--+--+--Oviraptorosauria sensu stricto

| | `--Microvenator

| `--Caudipteryx? sp.

`--Caudipteryx zoui
| `--+--Segnosauria

`--Protarchaeopteryx
`--+--+--+--+--+--+--Yandangornis+Pygostylia

`--Rahonavis

`--Microraptor

| `--Deinonychosauria (incl. Sinornithosaurus,
Bambiraptor, Achillobator)
`--Bagaraatan
What an odd phylogeny. The Avimimus + Ornithomimosauria
clade is like Makovicky 1995, while the placement of alvarezsaurids close to
ornithomimosaurs is similar to Martin's hypothesis. Placing "enigmosaurs"
in the Arctometatarsalia is rather unique...
By the way, you misspelled Sauriurae.
