Hello, I'm kind of new here and I thought
I'd introduce myself on the list (though I've
been lurking around the archives for the past year or so.)
My name is Jamie Stearns. I am 18 and going into
college, hopefully to become a paleontologist.
I've been interested in dinosaurs since I was 5,
and have recently completed a massive cladogram
containing every taxon I could find sufficient
information on, using several different websites
as well as the archives of this list. I have
attempted in most cases to find pictures or
diagrams of the actual skeletal material to
base my conclusions on, though much of it is
somewhat of a compromise between different
analyses. Due to the size of it, I'm going to
start by posting a small part of it here.
Non-Coelurosaurian Theropods:
|--Ornithischia
|--Sauropodomorpha
|--Guaibasaurus
|--Eoraptor
|----Herrerasaurus
| `--Staurikosaurus
|--Segisaurus
|--Procompsognathus
|--Coelophysis
|--Syntarsus
|--Gojirasaurus
|--Liliensternus
|--Dilophosaurus
|-----Elaphrosaurus
| |--Spinostropheus
| |--Ceratosaurus
| |--Rugops
| |----Masiakasaurus
| | `--Noasaurus
| |----Abelisaurus
| | `--Indosuchus
| |--Ekrixinatosaurus
| |----Aucasaurus
| | `--Carnotaurus
| |--Majungasaurus
| `--Rajasaurus
|-------Megalosaurus
| | `--Poekilopleuron
| |--Torvosaurus
| |----Baryonyx
| | `--Suchomimus
| |--Irritator
| `--Spinosaurus
|--Eustreptospondylus
|--Gasosaurus
|-----Cryolophosaurus
| |--Piatnitzkysaurus
| |--Afrovenator
| |--Monolophosaurus
| |--Fukuiraptor
| |-----Siamotyrannus
| | |--Metriacanthosaurus
| | |--Sinraptor
| | `--Yangchuanosaurus
| |--Allosaurus
| |--Neovenator
| |--Acrocanthosaurus
| |--Tyrannotitan
| |--Carcharodontosaurus
| |--Giganotosaurus
| `--Mapusaurus
`--Coelurosauria
I could not find much information on *Dubreuillosaurus*
and the identity of *Shuvosaurus* seems somewhat
problematic, so I'm not sure exactly where to put either one.
I agree with Rauhut on the placement of *Dilophosaurus*
as well as the inclusion of *Afrovenator* within Carnosauria
(however, I find it to be somewhat more basal than Rauhut).
Piatnitzkysaurus may belong here too, as it also seems to
have the characteristic lacrimal ornamentation and the
narrow frontal between the eyes shared by other
carnosaurs, though I'm not sure its lacrimal is known.
I'm not sure why coelophysids are considered
monophyletic. *Gojirasaurus* and *Liliensternus*, at
least the reconstructions I've seen of them, appear to
be closer to *Dilophosaurus* at least in size and robust
build than either is to *Coelophysis*, though I may be
missing something here.
Finally, *Elaphrosaurus* and it's relative *Spinostropheus*
are also pretty hard to place, given that they're alternately
placed as coelophysids (well, *Elaphrosaurus* at least),
more derived ceratosaurs, basal abelisaurs, or even close
to the beginning of Noasauridae. I have them as basal
to (*Ceratosaurus*+Abelisauria) at the moment.

Jamie,
Holy momma of Willi Hennig! And you're only 18? When I was 18, I tried
studying the behavior and classification of female humans. I failed a
couple tests and never got a degree in it (and, oh man, it still shows).
Welcome to the House Of Saurus. Rest assured that we only eat the
infants and the stragglers. Healthy older juvies like you have nothing
to fear. We mostly come out in the morning and afternoon. Mostly.
