 - Yay!  Tyrannosauroids are now coelurosaurs.
 - Proceratosaurus is a coelurid.
 - Therizinosaurus, Nanshiungosaurus and Neimongosaurus are segnosaurs.
 - Pelecanimimus is a deinocheirid.
 - Sereno-esque non-avepectoran segnosaurs.
 - The lone maniraptorans change position (Yixianosaurus sister to
Avepectra; Protarchaeopteryx as basalmost paravian; Pyroraptor in
Troodontidae).
 - Archaeornithoides is a troodontid, close to Byronosaurus.
 - Troodontidae rearranged, with Byronosaurus most basal, and
Saurornithoides monophyletic.
 - Paulian non-eumaniraptoran archaeopterygids, and scansoriopterygids
follow them there.
 - Microraptor/Cryptovolans as basal deinonychosaurs.
 - Unenlagia as a basal avialan.
 - Long-tailed avialans paraphyletic.>

  Wow ... for once, this analysis really seems to be producing results
resembling the consensus of the rest of the 21st century research.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
