Re: Coelurosaur phylogeny

["Ivan Kwan" <dino_rampage@hotmail.com>]

OK, so while everyone here is arguing whether to use Segnosauria or 
Theriznosauria, my questions are still unanswered. Basically,

1) Are _Compsognathus_, _Sinosauropteryx_, _Proceratosaurus_ & 
_Ornitholestes_ considered basal maniraptors, basal maniraptoriformes or 
basal coelurosaurs? And what is their phylogenetic placing relative to 
tyrannosaurs & ornithomimosaurs?

2) Are tyrannosaurs considered outside maniraptoriformes & thus classified 
as basal coelurosaurs?

3) Are ornithomimosaurs a part of maniraptoriformes or also basal 
coelurosaurs?

I've come up with 3 arrangements here:

1) Coelurosauria includes tyrannosaurs & maniraptoriformes. 
Maniraptoriformes includes (in order) ornitholestids, compsognathids, 
ornithomimosaurs & maniraptors.

2) Coelurosauria are ornitholestids, compsognathids & maniraptoriformes, 
which is made up of tyrannosaurs, ornithomimosaurs & maniraptors.

3) Coelurosauria is same as (2), except that compsognathids & ornitholestids 
are basal maniraptors.

which one is closest?
