Indeed.
Though, a cladogram without lines is in some places difficult to read.

What about letting it go after the K-T boundary?

Before Carl Sagan?

And now a long list of comments...

Dromaeosauridae: I don't know how much confidence you have. I'd be bold
enough to write

*Dromaeosauridae* _sensu lato_
# ? [_incertae sedis_] *Megaraptor*
# [_incertae sedis_] *Nuthetes*
# ? [_incertae sedis_] *Ornithodesmus*
# [_incertae sedis_] *Pyroraptor*
# [_incertae sedis_] *Variraptor*
#
  # *Microraptor*
  # ? *Cryptovolans*
#
  # *Sinornithosaurus*
  #
    # *Bambiraptor*
    # *Dromaeosauridae* _sensu stricto_
      # *Velociraptor*
      # *Dromaeosaurinae*
        #?
          # *Deinonychus*
          # *Saurornitholestes*
        #
          # *Achillobator*
          # *Adasaurus*
          # *Dromaeosaurus*
          # ? *Unenlagia*
          # *Utahraptor*

You separate *Archaeopteryx* and *Wellnhoferia*... but why not *Archaeornis*
and *Jurapteryx*?

Why is *Jinzhouornis* a confuciusornithid? What have I missed?
BTW, maybe you should include undefined clade names -- although not in
italics. :-) Would make reading easier, because lots of names are going to
stay undefined for quite some time.

*Sapeornis* points out the remaining problem of apomorphy-based definitions:
it certainly is outside the node-based *Pygostylia*, but it could be inside
the apomorphy-based *Avebrevicauda*. ... Maybe write *A.* in both possible
places, and in a color, to indicate that the placement of that name is not
sure.

I'm confident that *Jibeinia* is outside Ornithothoraces. But *Protopteryx*
and *Longipteryx* could be Enantiornithes... my analysis has failed to find
them elsewhere. In any case *P.* is more basal than *L.* (even when, as it
happens in my analysis, the 7 sacrals of *P.* are a reversal). -- 
*Eoenantiornis* could have 2 separate phalanges per 3rd finger, like *P.*,
*L.* and *Eocathayornis*... which you forgot. :-)

*Liaoningornis* is _incertae sedis_.

I'm confident that *Avisauridae* is real. I'm also confident that
*Cuspirostrisornis** is either a member or a very close relative.
*Concornis*, probably *Enantiornis* and apparently *Eoalulavis* are close
relatives, too. *Sinornis* appears to be close, even though its rather big
toe claws were not in my matrix.

* In my matrix *C.* differs from *Neuquenornis* only in the position of its
question marks.

*Lectavis* may not even be enantiornithine.
*Nanantius* is Ornithothoraces incertae sedis -- it could be a derived
enantiornithine, or related to *Apsaravis*, or who knows.

There are 2 definitions for *Ornithuromorpha*... following one (in a figure
caption, 2001) *Vorona* is one, following the other (in the main text, 2002)
it isn't.

*Yixianornis* has a few derived characters that *Yanornis* AFAIK lacks.
Namely, it has a small extensor process on mc I, a shorter thumb, the tip of
its pygostyle appears to be upturned a bit, and the tip of its pmx is
toothless; the latter 2 characters are not in my analysis.

What synapomorphies do *Ambiortus* and *Otogornis* share? (I got the latter
as an enanti, despite its euornithine shoulder.)

Separate *Ornithurae* _sensu stricto_ (Gauthier & de Queiroz 2001; includes
*Apsaravis* and maybe *Yixianornis*) and _sensu strictissimo_ (node-based).
:-) -- Is *O.* _sensu medio_ defined?

Where is *Carinatae* _sensu lato_?

*Palintropus* could be a pangalliform, according to Hope's chapter in
Mesozoic Birds.

What is *Omorhamphus*? I only know *Diatryma*...

Where does your phylogeny of *Neoaves* come from?

What does *Opisthocomidae* do between all those traditional gruiforms? It's
the sistergroup of *Musophagidae* (turacos). -- And it's *Opisthocom_us_*.

What about the molecular results that find flamingos and grebes as
sistergroups?
