Grant,
      Nice site.  I would suggest adding Dryptosaurus at the base of your
tree (and perhaps Proceratosaurus even basal to that).
      I based my latest classification (posted in early July) in part on
some of Mickey Mortimer's analyses, so there are some definite similarities.
  I would personally prefer to keep Compsognathines in a separate clade from
Scipionyx and from Coelurus, and I definitely think Ornithomimes split off
in a more derived position (after Nqwebasaurus).
      Tyrannosauroids might have split off before Nedcolbertia, but it is
difficult to pin them down to a particular spot.  And I still believe
"Enigmosauria" is probably paraphyletic (with therizinosaurs splitting off
between ornithomimes and oviraptorosaurs as I noted in my recent
classification of neotheropods---see below).
********************************************

There IS tyrannosaurid teeth from the Late Jurassic in North America and
Portugal (See Ford and Chure at the poster section at this years SVP). Also
Stokesaurus does have tryannosaurid affinities. They must have split off
before that.
