This is an unpublished name. The correct term
for this clade (Maniraptora + Ornithomimus) is Maniraptoriformes.

Interesting placement. Might I ask why you
think Timimus is an avimimid?

Hmm. My comment on
these two was that they're both comparable, not that they're both
related.

In this case, your Tyrannoraptora clade
(Tyrannosaurus + Neornithes) would actually be termed Paraves (closer to
Neornithes than to Oviraptor). Eumaniraptora (Deinonychus + Neornithes)
would be one step higherthan you have it, uniting Aves and
"Dromaeosauroidea". Why do you use "Dromaeosauroidea" when
Deinonychosauria (everything closer to Deinonychus than to Neornithes) would
work well here?

Regarding your Iliosuchidae, why do you include
Eotyrannus? Are you aware that the only element we could even compare in
Eotyrannus and Stokesosaurus is the premaxilla? The ilium of
Eotyrannus is very fragmentary. Dinotyrannus and Nanotyrannus are both
young Tyrannosaurus rex (Carr, 1999). Shanshanosaurus seems to be a
juvenile Tarbosaurus (Currie and Dong, in prep.). Aublysodon is an
indeterminate juvenile tyrannosaurid tooth, but remains referred to it have been
shown to be Daspletosaurus (OMNH specimen) and Tyrannosaurus (Jordan
theropod). As Aublysodon teeth have been reported from many sites ranging
from Kimmeridgian-Maastrichtian, they are probably simply the teeth of juvenile
tyrannosaurids.
